|Diff HDD||Reading and writing are processed respectively in parallel by separate threads.|
|Same HDD||Reading is processed until the big buffer fills. When the big buffer is filled, writing is started and processed in bulk.|
|1. The last character of DestDir is '\'||
Copy Source directory, including itself, to DestDir.|
|2. The last character of DestDir is NOT '\'||
Copy Source directory's contents to DestDir.|
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)
|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.|
|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 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)|
|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.
(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.|
|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.|
|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.|
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.)
|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.|
|Open Log||Open FastCopy.log|

|Support Forum||Questions/Opinions about FastCopy|
|Latest Version||Open FastCopy WebPage|
|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)
|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 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.
|Enable Large fetch mode (Win7 or later only)||Enable FIND_FIRST_EX_LARGE_FETCH flag and improve directory fetch performance.|
|Manual settings of physical drive group|
|About||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"|
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|
|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.|
|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 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.
|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)|
|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|
|Use UTF-8 in Errlog||Using UTF-8 character in FastCopy.log. Otherwise using MBCS.|

|English UI||(It has no effect in English OS) English UI mode will be set. In order for English UI to take effect, you need to restart FastCopy|
|ActionName||By default, Normal/Standby/Hibernate/Shutdown are ready.|
New actions can be created.
|Play Sound||Play sound at finish|
Only play, if error occurred option is available.
|Execute command||Specify commands at finish.|
Execute at Always/no error/error" can be specified.
If "Wait for Finish" is checked, FastCopy won't execute standby/hibernate/shutdown until finishing commands.
|Before executing to standby/hibernate/shutdown mode, FastCopy shows count down(60sec) dialog that has a "cancel" button.|
If another FastCopy is running, FastCopy will wait for it to finish and start to count down.
|Grace||The count-down time can be specified.|
|Don't execute, if error occurred.||execute only if succeeded|
|Add/Modify||Add/Modify parameters in main window(Source/DestDir, Operation mode, Buffer size, Nonstop/Verify/Estimate/ACL/AltStream/Wipe&Delete/Filter checkboxes, Filter strings, HDD mode) as named job.|
|Delete||Delete registered job.|
