1. The last character of DestDir is '\' |
Copy Source directory, including itself, to DestDir. (DestDir\SourceDir\Contents_of_SourceDir) |
2. The last character of DestDir is NOT '\' |
Copy Source directory's contents to DestDir. (DestDir\Contents_of_SourceDir) However, if multiple directories are specified in Source, the behavior will be changed to 1. (mini tips) If you want to copy Source directory's contents to the DestDir that is specified drive root, please append "*" to Source directory. For example, if Source is "C:\Folder1\*" and DestDir "D:\", the result is D:\(Contents_of_Folder1) |
Mode | Detail |
---|---|
Diff (No Overwrite) | Copy if the same filename does not exist in destination. |
Diff (Size/date) | Copy if size or date is different, or if it does not exist (in default) |
Diff (Newer) | Copy if source file timestamp is newer or does not exist. |
Copy (Overwrite) | Always copy/overwrite all. |
Exist (Size/date) (Pro Only) |
Copy if the same file name exists and the size or date is different. (Files that do not exist will not be copied.) |
Exist (Newer) (Pro Only) |
Copy if the same file name exists and source file timestamp is newer. (Files that do not exist will not be copied.) |
Sync (Size/date) | Copy if size or date is different or it does not exist. In addition, delete all destination files/directories that do not exist in Source. |
Sync (Newer) | Copy if date is newer or it does not exist. In addition, delete all destination files/directories that do not exist in Source. |
Move (Overwrite) | Always copy/overwrite all and delete all copied source files. (To change select "Move (Overwrite all)" → "Move (Size/date)" in the settings dialog.) |
Move (No Overwrite) (Pro Only) |
Only files that do not exist at the destination are copied. Only copied files are deleted from the source. (Files that are not copied are not deleted.) |
Delete | Delete all files/dirs forcibly. |
Verify | Mutual hash comparisons are performed for files with matching sizes and timestamps in Source and DestDir. (Note: Source and DestDir should be the same description as when just copying. For example, if you want to compare C:\temp\ and D:\temp\, please describe C:\temp\ in Source and D:\ in DestDir) |
FC Verify Info Disp | Displays record information for files with FC verify information (:fc_verify) |
FC Verify Info Check (Pro Only) |
For files with FC verify information (:fc_verify), recalculate & compare the current hash value with its recorded information to verify that silent data corruption has not occurred. |
Execute | The copy operation is executed. While executing, the button changes to "Cancel..." button. - While pushing CTRL, the confirmation dialog is displayed. |
Listing | The files and directories list that will be copied and deleted are displayed. '+' means copying, and '-' means deleting. - While pushing CTRL (button label "listing" → "listing+v"), compare the file pairs that will be skipped (except skipping by filter). - While pushing Shift (and if filelog is enabled), write listing contents to filelog. (If FileDate/FileSize option in log settings is enabled, this information will be shown/written) |
Buffer size | Show the size(MB) of the main buffer for Read/Write operations. If it is clicked, setting dialog will be opened. |
Speed Control | Specify "Full Speed", "Auto Slow"(*1), "90%"~"10%", "Suspend". If you feel it is hogging resources, it is recommended to set to "Auto Slow" (If mouse movement is detected, or active window is changed (and FastCopy window is not in the foreground), it will be slowed down). If "Full Speed" is not selected, low process priority class is set. (This setting is not saved by job manage) |
NonStop | Don't interrupt even if errors occur by Read/Write/Delete, and keep processing as much as possible. (However, errors are displayed in the main window, and recorded in the error log.) |
Verify |
Verify written files data by xxHash3 (MD5/SHA-1/SHA-256/SHA3-256/SHA3-512/xxHash). (If you want to use MD5/SHA-1/SHA-256/SHA3-256/SHA3-512/xxHash, it can be selected in Verify Options of settings.) There are two types of verification: Conventional verification (re-reads only Dest) and Perfect verification (re-reads both Src and Dest. Pro version only). (Perfect verify can also detect temporary errors when reading Src.) if verify error occurs, hash values of src/dest are shown, and it is renamed dest-filename with .fc_verify_err. (Depending on the setting, it can be removed(or etc) it instead of renaming) |
Estimate | Display the estimated complete time. This will make FastCopy investigate files/dirs to be copied, before starting. |
Start at once | Start at once without waiting for other FastCopy instances executing to finish. (This button does not show when another FastCopy is not copying.) (parallel running) |
ACL | Copy Access Control List (ACL). (Only applicable to NTFS) (It is recommended to use with Administrative privilege) In addition, Extended Attribute(EA) will also be copied. |
Alt Stream | Copy Alternate Stream. (Only applicable to NTFS) |
Wipe & Delete (prevent deleted files reviving) | Rename filename and Overwrite random data before deleting. Alternate stream is not overwritten. If NSA method is checked in setting dialog, Overwriting Random data process runs twice, and overwriting NULL data process runs once. |
Include | Only files or directories that match the specified string (UNIX wildcard format is allowed) will be copied. Include filter strings can be specified (UNIX wildcard format). (Note) If you want to specify two or more strings, please use semicolon as separator. If you want to specify directories, please add '\' to the end of directory name. Ex1) *.txt → a.txt, 123.txt or etc files will match Ex2) [^ax]bc → bbc or etc files will match, but not abc or xbc Ex3) dir[0-9][234] → dir12 or etc will match, but not dir1 or dir10 |
Exclude | Don't copy files/directories that match the specified strings. |
The following filters are enabled when "Option" → "Show Extended filter" is checked. | |
FromDate | Don't copy files with timestamps older than a specified date(format). This can be specified by not only absolute format ("20090322" or "2016/09/26 12:30:56") but also by relative format (10 days before ... "-10D"). |
ToDate | Don't copy files with timestamps newer than this specified date. |
MinSize | Don't copy the files with sizes that are smaller than the specified size. High number can be abbreviated using K/M/G/T character (Kilo/Mega/Giga/Tera). |
MaxSize | Don't copy the files with sizes bigger than the specified size. |
Relative path filter |
If the first character of Include/Exclude string items is not '\', it will be Relative path filter. This mode is tail matching policy.
| ||||||||||||||||||||||||
Forward match filter |
If the start character of Include/Exclude string items is '\', it will be Forward match filter. This mode is head → tail matching policy. For example, if Source is C:\aa\, and you want to exclude C:\aa\bb\cc\, Forward match filter is \bb\cc\. Remove Source (C:\aa\) from the path you want to exclude (C:\aa\bb\cc\) and add \ at the beginning to indicate a forward match.
| ||||||||||||||||||||||||
Absolute path filter |
If the first character of Inlcude/Exclude starts with a drive letter (for example, C:\) or a UNC path (for example,\ \server \volume\), it is an absolute path specification. The absolute path must include the source path. Internally, it is converted to a forward match specification. (The absolute path minus the following "Start point of filter check" is registered as a prefix match) | ||||||||||||||||||||||||
(Remarks) Start point of filter check |
If Source is either C:\src\, C:\src\file.txt or C:\src\dir*, the start point(beginning) of the filter check will be C:\src\ |
* | Zero or more arbitrary characters |
? | One arbitrary character |
[abc] | One character in "abc" |
[!abc] | One character except "abc". '^' can also be used instead of '!'. |
[a-z] | One character in "abc...xyz" |
\ | '\' as Start character means Forward match filter. The middle of '\' is separator of path items. In addition, the end of '\' means "This is a filter item for directory". However, '\' in character class([]), it means escape character. |
Absolute | Specify "YYYYMMDD[hhmmss]"(year/month/day/hours/minutes/seconds). ex) "20090322" or "2016/09/26 12:30:56" |
Relative | Specify "+|- number W|D|h|m|s". W|D|h|m|s means Weeks/Days/hours/minutes/seconds. ex) "-12h" (This is case sensitive.) |
Mode | Details |

About FastCopy | Show Version and Copyright |
Default parameters for Main Window | The detail is this. |
Language | Change Language. (need to restart) |
Main Buffer (MB) | Specify main buffer size for reading/writing. |
I/O unit (MB) | Parallel Read/Write request unit size for OS. "I/O unit" * "OverLap I/O Num" is the (effective) Max I/O size for OS. 1MB I/O unit size is the best performance for many environments, especially if network drive is used. (Buffer size must be at least twice the Max I/O Size) |
OverLap I/O Num | I/O performance(especially network drive) is improved by using overlapped ReadFile/WriteFile I/O. (If it is specified "1", it will not be used overlapped I/O) |
Always use Low IO | Gives I/O priority to other apps. (Use Low-Priority I/O in Vista and later) |
For SD cards, don't use OverLap I/O | Due to problems with some old SD card adoptors |
OS Cache settings | |
---|---|
Use OS buffer for reading | It does not use DirectI/O. OS is likely to be slow/heavy, it can not be recommended. |
Use OS buffer for writing | It does not use DirectI/O, if the filesize is under the specified size(KB) The disadvantages are the same as for reading. It will be faster for only very small files that use Direct I/O because of less head seeking time. |
Directory Fetch | |
---|---|
Enable Large fetch mode (Win7 or later only) | Enable FIND_FIRST_EX_LARGE_FETCH flag and improve directory fetch performance. |
Verify mode | Select the verify method
|
Hash mode (for verify) | Select Hash mode (xxHash3/xxHash/MD5/SHA-1/SHA-256/SHA3-256/SHA3-512) for verifying. (xxHash3 is recommended.) | ||||
At verify error, | Choose from the following four options.
|
||||
Set timestamp to 1980-01-02 until verification completes. |
The timestamp will be 1980-01-02 from copy/move until verification is completed. When copying with verification is interrupted, files that have not been verified can be identified. |
||||
Files dated 1980-01-02 will be resumed from verification (Size/Date or Latest only. Perfect verify only) |
Files dated 1980-01-02 that occur when Copy/Move/Sync with Perfect Verify is interrupted, will resume from verification (skip copying). (Size/Date or Latest mode only) (In "Move/Sync Settings", it can be changed "Move (Overwrite)" to "Move (Size/Date)") |
||||
Verify every 30 secs |
Verification is performed every 30 seconds (to the extent possible). (The default behavior is to verify after all copies are completed (except when the verification queue is full) in order to minimize the effects of caches on the device.) |
Add VerifyInfo | The AltStream(:fc_verify) is added at completion of the verified copy. (To detect silent data destruction) {done=complete date and time, ftime=file date and time, size=size, xxHash=Hash value} In the case of a verification error, it will look like this {error=complete date and time, ... , xxHash(src=hash value, dst=hash value)} This information can be displayed and verified by "FC Verify Info Disp" and "FC Verify Info Check". |
If not verifying, record the src hash value in the file log | (same as left) |
Drives that are always run in parallel (e.g. SSD-RAID) | |
---|---|
Details | Specifies drives that are faster when run in parallel, such as SSD-RAID. It always operates as diff HDD mode. It also does not queue up even if multiple FastCopy are running. |
How to specify | If C: and E: are SSD-RAID, specify "CE". For drives with UNC pathnames, please assign a drive letter. |
Manual settings of physical drive group | |
---|---|
Details | Specify same physical drive group. |
Format | If C: and D: are the same physical HDD, and E: and F: are the same, please specify "CD,EF" For drives with UNC pathnames, please assign a drive letter or specify the decision policy below. |
Physical drive group decision policy of network drive | |
---|---|
Details | Network drives are in the same physical HDD(or SSD) or not This decision policy always uses UNC name even if it is specified as the drive letter that is a network drive (*2) |
Same UNC_share are same physical drive group. | If UNC name is \\Server1\vol1\, \\Server1\vol1\ is the same physical HDD group, and \\Server1\vol2\ is not the same. |
Same UNC_server are same physical drive group | If UNC name is \\Server1\vol1\, \\Server1\ is the same physical HDD group, and \\Server2\... is not the same. |
All UNC_server are same physical drive group | All Network drives are the same HDD group |
Max number of running FastCopy procs | If a lot of of instances of FastCopy are running in parallel, it requires much memory and CPU resource. If another FastCopy already running uses the same physical HDD, FastCopy will wait for the previous FastCopy to finish. Manual settings physical drive group is available. |
---|---|
Don't wait for another FastCopy running to finish | (Ignore the above settings) It always starts quickly. |
CPU affinity |
Determines whether Read and Write threads are pinned to a logical CPU core. In some environments, tying Read/Write threads to logical CPU cores improves I/O performance. (When multiple FastCopy threads are running simultaneously, they are automatically distributed so that they are allocated to each other as little as possible) |
---|
Don't create empty directory, if "filter" is checked | After using the filter, if there isn't a file for copying, FastCopy won't make directories. |
Use a modified name, if destdir is the same as src's parent | If DestDir is the same as src's parent directory, create a new name like "source(1)" and continue |
Copy Junction/Symlink as Junction/Symlink(not target) | Copy Junction/Symlink as Junction/Symlink. If this check is off, it will be copy Junction/Symlink's target directory/file (*1) (This option is ignored in "move" or "delete" mode) Note: It requires administrator privilege to create Symlink |
Shared open Dest on Copy/Move (a little dangerous) | Opens the write destination non-exclusive. This increases the possibility that you can write to a file that is open by another process, but the file contents can be corrupted if another process writes to it. |
Reproduce Hardlink | Reproduce hardlink as much as possible. (details) |
Tolerance at the timestamp comparison | Specify tolerance timestamp difference as same date in Diff(Date/Size) or Diff(Newer). Normally, FastCopy corrects timestamp difference on the different filesystem(NTFS timestamp precision is 100ns, FAT is 2sec or etc.), automatically. However, some NAS timestamp precision is very strange, so manual settings(in msec) are available. |
DST mode | |
---|---|
Always disallow DST grace time | |
Allow DST grace time(60min) with FAT | |
Always allow DT grace time(60min) | |
PreAllocate for speed (Admin only) | |
By pre-allocating space in privileged mode, a 20-30% speed increase can be achieved on high-speed SSD-RAIDs and similar systems. Options include always performing this action, limiting it to local drives only, and more. |
Move options | |
---|---|
Change "Move(Overwrite)" to "Move(Date/Size)" | If there is a file with the same date and size as the move destination, it is deleted from the move source without copying. |
Move one by one | Normally it won't delete original files until the move files list is full. This option changes the behavior to "a file has copied, and remove copied source file" |
Move one by one (verify) | It is the same as "Move one by one" except "remove copied source files" → "remove verified source files" |
Sync options | |
---|---|
Delete before copying | The destination files that will be overwritten, or that don't exist in the source, are deleted before copying process begins. (directory tree scan will be performed twice, once for deletion and once for copying, so if there are a lot of files, the copying process will be a little slower. |
Try to delete directory, even if "Filter" is checked. | By default, it does not delete directory, if "Filter" is checked. If it is checked, it always tries to delete directories. (attention) |
Use NSA method for Wipe & Delete option | If "Wipe & Delete" option is used, it is overwritten 3 times (random-data 2 times and zero-data 1 time), before renaming and deleting |
Number of history items for Source/DestDir | need to restart FastCopy |
Write to Error log | Logging error message to FastCopy.log |
Write ACL errors to Error Log | Sometimes, many errors will occur in non NTFS (Samba, or etc.) |
Write AltStream errors to Error Log | Sometimes, many errors will occur in non NTFS (Samba, or etc.) |

Q. The setting file(FastCopy2.ini) and log files are created in the following directory. |
If FastCopy is installed to Program Files, these are created in C:\Users\(USER)\AppData\roaming\FastCopy\ (Menu File(F) → UserDir(U)) For other cases, these are created in the same directory as FastCopy.exe |
Q. I want to copy without additional subdirectories when DestDir is the drive root (e.g. D:\) |
The trailing \ of the drive root (e.g. D:\) cannot be deleted (an error will occur). In this case, append * to the Source side. For example, in the case of C:\src, it should be C:\src\*. |
Q. Slow when started from Task Scheduler |
This is because Windows forces processes launched from the Task Scheduler to have Low Priority I/O. To avoid this, select a task in the Task Scheduler, export it, delete it, change the <priority>7</priority> setting in it to 5 or lower, and import it. (Reference: search google for taskscheduler priority xml) |

v4.0.0 - 4.22 |
Added FcHash.exe (xxHash3/SHA-based fast hash calculation command line) Added to support AltStream for directories. Support WebHook Notification. (Send the completion notification to Slack or etc) OpenSSL is incorporated, and CPU usage when SHA-256 is used is reduced to 1/3 (& faster). Added option to always use LowI/O. Added SHA-512 mode to verify. Improved HDD I/O speed. Improved xxHash speed. |
v3.00 - v3.92 |
Added SHA-256, xxHash3(128bit) to Verify Type and changed default to xxh3 (automatically uses SSE2/AVX2/AVX512). Added verify information option when copying with verify. (Add (hash value, copy date, etc.) to the secondary stream (:fc_verify)) Added File Log History to the File menu. Added absolute path specification to Include/Exclude filter. Multi-threaded deletion process. (more than double via network) Multi-threading of Source open. (Especially effective on network drives) Faster directory search (for high-latency environments or large entries, using FIND_FIRST_EX_LARGE_FETCH). When ACLs are enabled, copying between local NTFS (or ReFS) with administrative privileges should copy SACLs as well as DACLs. The completion status is also indicated by the color at the top of the icon (green: completion, red: error). asynchronous I/O support, filter relative paths, optimized concurrency behavior. Enabled user-level (non-administrator) shell extension. Added OS cache settings for NetDrv. Added /time_allow=N(ms) option.
