1. About

FastCopy is the Fastest Copy/Delete Software on Windows.

It supports UNICODE and over MAX_PATH (260 characters) file pathnames.

It automatically selects different methods according to whether Source and DestDir are in the same or different HDD(or SSD).
Diff HDDReading and writing are processed respectively in parallel by separate threads.
Same HDDReading is processed until the big buffer fills. When the big buffer is filled, writing is started and processed in bulk.

Reading/Writing are processed with no OS cache, so other applications do not become slow.

It can achieve Reading/Writing performance that is close to the device limit.

Include/Exclude Filter (UNIX Wildcard style) can be specified. ver3.0 or later, Relative Path can be specified.

It runs fast and does not hog resources, because MFC is not used. (Designed using Win32 API and C Runtime only)

You can modify this software, because all source code has been opened to the public under the GPL ver3 license.

ver3.0 or later, FastCopy's settings file has been renamed from FastCopy.ini to FastCopy2.ini.

4. Installation

Installation

Please run FastCopy3xx_installer.exe, and install it in a new directory.
If you want to install in USB memory or etc, please use "Extract" button in installer.
run with /h option, it shows the installer options. (/silent, /extract or etc)

Uninstallation

If you want to uninstall, please run setup.exe located in the installed directory.
In Win7 or later, you can uninstall from "Apps & features (or Program and Features)" in the OS settings.
run with /r /silent option, it means silent uninstallation.

5. Usage & Main Window

Main window when minimized appears in task notification area.
When running, various statuses are displayed.
(Inside the file number's parentheses is the number of directories.)

Source / DestDir

Operation mode

ModeDetail
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.
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.
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.)
Delete Delete all files/dirs forcibly.

Buttons & Options

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 xxHash (MD5/SHA-1/SHA-256).
(If you want to use MD5/SHA-1/SHA-256, it can be selected in
Copy/Move Options of settings.)
Action detail: Read(Src) -> xxHash(Src) -> Write(Dst) -> Read(Dst) -> xxHash(Dst) -> Compare xxHash(Src/Dst) (All actions are processed in parallel as much as possible)

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 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)
(*1) It is slowed down if the FastCopy window is not in the foreground and mouse movement is detected, by waiting between I/O, changing process priority, changing I/O priority, and changing maximum I/O size.

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.

Filter Options

It can Include/Exclude the copy target files/directories that match/unmatch by filters.
Select the "listing" button to confirm the copy target files/directories list.

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.
(For example: *.txt; My Folder [0-9]\)
ver3.0 or later, relative path filter is available.
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.

Note 1) In delete mode, it does not delete directories when "only files and not directories" are specified in the Include field.
Note 2) When one or more files are specified in the Include field, files that do not match are not copied.
Note 3) When one or more directories are specified in the Include field, directories that do not match are not copied.

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.
Example of the directory Include
SourceC:\dir\
Includesubdir[1-9]\xxx\
Match examples C:\dir\subdir2\xxx\
C:\dir\aaa\subdir3\xxx\
EffectMatched directories and all under them will be copied.
Example of the file Include
SourceC:\dir\
Includesubdir[1-9]\file.*
Match examples C:\dir\aaa\subdir2\file.txt
C:\dir\bbb\ccc\subdir3\file.doc
EffectMatched files will be copied.
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.
Example of the directory Include
SourceC:\dir\
Include\subdir[1-9]\xxx\
Match examples C:\dir\subdir2\xxx\
C:\dir\subdir3\xxx\
EffectMatched directories and all under them will be copied.
Note (unmatch example)C:\dir\aaa\subdir2\xxx\ ... different hierarchy.
Example of the file Include
SourceC:\dir\
Include\subdir[1-9]\file.*
Match examples C:\dir\subdir2\file.txt
C:\dir\subdir3\file.doc
EffectMatched files will be copied.
Note (unmatch example)C:\dir\aaa\subdir2\file.txt ... different hierarchy.
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\

Include/Exclude filter(wildcard) format.
*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.


FromDate/ToDate filter format.
AbsoluteSpecify "YYYYMMDD[hhmmss]"(year/month/day/hours/minutes/seconds).
ex) "20090322" or "2016/09/26 12:30:56"
RelativeSpecify "+|- number W|D|h|m|s".
W|D|h|m|s means Weeks/Days/hours/minutes/seconds.
ex) "-12h" (This is case sensitive.)

Junction and SymLink

Junction(include MountPoint) and Symlink is supported in ver1.70 or later.
ModeDetails
Diff/Copy Copy Junction/Symlink itself.
If you want to change the copy Junction/Symlnk's target(not Junction/Symlnk itself), it can be changed in the options settings
Move Always move Junction/Symlink itself.
Delete Always delete Junction/Symlink itself.

HardLink

HardLink can be reproduced as much as possible, when /linkdest option is specified. (in ver1.95 or later).
(The display of "TotalFiles:" changes from "number_of_files (number_of_dirs)" to "number_of_files / number_of_created_hardlinks (number_of_dirs)").

Two very important notes:
1. It needs 2-4MB per 10 thousand hardlink files. (It depends on path length)
2. The speed will drop, because all files are opended to obtain the number of links.

If /linkdest option is enabled, /recreate option is enabled tacitly.
If you want always to enable /linkdest option, write [main] linkdest=1 in FastCopy2.ini file.

6. Settings

Settings -> Main Settings

Main settings. (change Default values, I/O parameters, and Copy Options, etc.)

Defaults

Specify default parameters for Main Window
Default parameters for Main WindowThe detail is this.
LanguageChange Language. (need to restart)

I/O settings

fundamental parameter of I/O
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 NumI/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)
MinSectorSize is regarded as 4KB If destination drive are 512B sector HDD that has mounted 4KB sector HDD, please check this.

OS Cache settings
Use OS buffer for readingIt does not use DirectI/O. OS is likely to be slow/heavy, it can not be recommended.
Use OS buffer for writingIt 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.

Drive Group

Settings of physical drive group (*1)
FastCopy detects physical drive group automatically. However, in some situation(RAID,TrueCrypt or etc.), it can not detect automatically and it requires manual settings.
Manual settings of physical drive group
AboutSpecify same physical drive group.
FormatIf C: and D: are the same physical HDD, and E: and F: are the same, please specify "CD,EF"
If you use UNC path, you can assign the drive letter for UNC or specify set decision policy below.

Physical drive group decision policy of network drive
DetailsNetwork 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 groupIf 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 groupAll Network drives are the same HDD group
(*1) If Parallel Read/Write are issued in the same physical HDD, it will be slow because many HDD head seeks will occur. So FastCopy has two running modes as same or diff HDD mode.
(*2) If your network bandwidth is not enough, it is recommended to choose "All UNC_server are same"

Parallel running

Specifying the number of parallel running FastCopy.
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.

Copy/Move Options

Copy/Move options
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
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"
Tolerance at the timestamp comparisonSpecify 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.
Hash mode (for verify) Select Hash mode (xxHash/MD5/SHA-1/SHA-256) for verifying.
If a verify error occurs,
delete the file instead of renaming to .fc_verify_err
(Same as left)
(*1)For example, "C:\Users\(user)\AppData\Local\Application Data" points to "C:\Users\(user)\AppData\Local". If you try to copy this with "Copy Junction/Symlink as Junction/Symlink" disabled, it will infinitely recurse. (C:\Users\(user)\AppData\Local\Application Data\Application Data\Application Data\...). Therefore, be careful when you disable "Copy Junction/Symlink as Junction/Symlink".

Delete options

Delete options.
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
