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, as such other applications do not become slow.

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

5. Usage & MainWindow

Main window when minimized appears in task tray.
Main status be shown at running.
(numbers of parens indicates the number of directories)

Source / DestDir

Operation mode

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 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. (It is able to change "Move (Overwrite all)" -> "Move (Size/date)" in settings dialog.)
Delete Delete all files/dirs by force.

Buttons & Options

Execute The copy operation is executed. While executing, the button changes to "Cancel..." button.
- With 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.
- With pushing CTRL(button label "listing" -> "listing+v"), compare the file pairs that will be skipped(except skipping by filter).
- With pushing Shift(and if filelog is enabled), write listing contents to filelog. (If FileDate/FileSize option in log settings is enabled, these information will be shown/written)
Buffer size Specify the size(MB) of the main buffer for Read/Write operations.
(ver3.0 or later, 64bit version can be specified 4096(MB) or over.)
(More than twice value of Max I/O Size is required)
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 it detects mouse moving/active window changing (and FastCopy window is not foreground), it is 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 MD5 (/SHA-1/SHA-256/xxHash).
(If you want to use SHA-1/SHA-256/xxHash, it can selected in
Copy/Move Options of settings.)
... Action detail: Read(Src) -> MD5(Src) -> Write(Dst) -> Read(Dst) -> MD5(Dst) -> Compare MD5(Src/Dst) (Of course, all actions are processed in parallel as much as possible)
Estimate Display the estimated complete time. This will make FastCopy to investigate files/dirs to be copied, before starting.
Top FastCopy window is always top-level.
Start at once Start at once without waiting for the finish of other FastCopy instance(s) executing. (This button does not show when other FastCopy is not copying.)(parallel running)
"?" Show help
(*1) It is slowed if FastCopy window is not foreground and it is detected mouse moving, by waiting beetween I/O, changing process priority, changing I/O priority(Vista or later), and changing maximum I/O size.

ACL Copy Access Control List (ACL). (Only applicable to NTFS)
(It is recommended to use with Administrative privilege)
And 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 two times, and overwriting NULL data process runs once.

Filter Options

It can include/exclude the copy target files/directories that match/unmatch by filters.
It can be confirmed the copy target files/directories list by "listing" button

Include It will only under the file or directory that match to the specified string (UNIX wildcard format allowed) to be copied. It can be specified include filter strings(UNIX wildcard format). (P.S)
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 the files/directories that match up specified strings.
The following filters are enabled when check "Option" -> "Show Extended filter".
FromDate Don't copy the files that timestamp are older than 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 (10days 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 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 specified size.

P.S It does not delete directories if include field is specified only files and not directories in delete mode.
P.S It does not copy the files that is not match by include filter if include field is used and spcecified files.
P.S It does not copy the directories that is not match by include filter if include field is used and specified directories.

Relative path filter If the start character of include/exclude string items is not '\', it is relative path filter. This mode is tail matching policy.
For example, Source is C:\dir\ and include is subdir[1-9]\xxx\, C:\dir\subdir2\xxx\ or C:\dir\dir\subdir3\xxx\ will be matched and it will be copies these directories and these childs.
If include is subdir[1-9]\file.*, C:\dir\zzz\subdir9\file.txt will be matched.
Start path filter If the start character of include/exclude string items is '\', it is start path filter. This mode is start matching policy.
For example, Source is C:\dir\ and include is \subdir[1-9]\xxx\, C:\dir\subdir2\xxx\ or C:\dir\subdir3\xxx\ will be matched, but C:\dir\dir2\subdir2\xxx\ will not be matched.
If include is \subdir[1-9]\file.*, C:\dir\subdir9\file.txt will be matched and C:\dir\dir2\subdir9\file.txt will not be matched.
Start point of filter check For example, the start point of filter check will be C:\src\, if Source is C:\src\, C:\src\file.txt or C:\src\dir*

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 ""
\'\' as Start character means Start path filter. The middle of '\' is separator of path items. And the end of '\' means "this filter item is directory". But '\' 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.
Diff/Copy Copy Junction/Symlink itself.
If you want to change the copy Junction/Symlnk's target, it can be changed in the options settings
Move Always move Junction/Symlink itself.
Delete Always delete Junction/Symlink itself.


HardLink can be reproduced as much as possible, if specified /linkdest option in ver1.95 or later.
(In running, "TotalFiles:" format changes "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 entity files. (It depends on path length)
2. It can decrease speed, because it opens not only copying files but also skip files.

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.

Menu items

6. Settings

Settings -> General Settings

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


I/O settings

fundamental parameter of I/O
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 is required more than twice value of Max I/O Size)
OverLap I/O Num(v3.0 or later)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)

OS Cache settings
Use OS buffer for readIt is not use DirectI/O. OS is likely to be slow/heavy, it can not be recommended.
on NTFS/on FATIt is not use DirectI/O, if the file that filesize is under than specified size(KB)
demerit points are same as read, but sometimes many head seeks occur in writing very small files by DirectI/O.

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. But in the 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 two ways that assign drive letter for UNC or specifying set decision policy in the following.

Physical drive group decision policy of network drive
DetailsNetwork drives are in the same physical HDD(or SSD) or not
This decision policy uses always 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 mode 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 for FastCopy.
Max number of running FastCopy procsIf you specify a lot of instance of FastCopy run, it requires many memory and CPU resource.
If other already running FastCopy uses the same physical HDD, FastCopy will wait for finishing the previous FastCopy.
Manual settings physical drive group is available.
Don't wait for other running FastCopy 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 The directory that has no file that match by filter, it does not create it
Use a modified name, if destdir same as src's parent If DestDir is the same as src's parent directory, create 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)
P.S It requires administrator privilege to create Symlink
Change "Move(Overwrite)" to "Move(Date/Size)" It will be removed (without copy) the files/directories that have same source's timestamp and size.
Move one by one Normally move behavior is "All file copy has copied (or move files list is full), and remove copied source files are removed in bulk)".
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"
Hash mode (for verify) Select Hash mode (MD5/SHA-1/SHA-256/xxHash) for verifying.
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.
But some NAS timestamp precision is very strange, so manual settings(in msec) are available.
(*1)For example, C:\Users\(user)\AppData\Local\Application Data points to C:\Users\(user)\AppData\Local. If it try to copy the pointed directory, it will be infinite recursion. (C:\Users\(user)\AppData\Local\Application Data\Application Data\Application Data\...)
So, it requires attention if "Copy Junction/Symlink as Junction/Symlink" checkbox is off.

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 try to delete directories. (attention)
Use NSA method for Wipe & Delete option If "Wipe & Delete" option is used, it is overwritten at 3 times (random data at 2 times and 0 data at 1 times), before renaming and deleting

Log Settings

It is recomended to use fixed pitch font.

Option -> Auto/Same/Diff HDD mode

Specify Auto/Same/Diff HDD mode(default: Auto).
CTL + K shortcut toggles between disk modes (auto -> same -> diff ->...)


Select Post-Process.
Allows user to change default settings (sound, command, and standby/hibernate/shutdown) after copy process/execution is complete. Also, user can add new Post-Process settings.
Post-Process Window

And it can be created new action.
Play SoundPlay sound at finish
Only play, if error occurred option is available.
Execute commandSpecify commands at finish.
Execute at Always/no error/error" can be specified.
If you check "Wait for Finish", FastCopy wait for finish these commands to execute standby/hibernate/shutdown.
Before changing to standby/hibernate/shutdown mode, FastCopy shows count-down(60sec) dialog that has "cancel" button.
If other FastCopy is running, FastCopy will wait for finish and start to count down.
GraceIt can be specified count-down time.
Don't execute, if error occurred.execute only if succeeded

Settings -> Show Extended Filter

Show Extended Filter(timestamp/size filter)

Option -> Swap Source <-> DestDir

Swap Source for DestDir (for mutual update or etc).
Source/DestDir will be modified based on
different behavior whether the end of DestDir character is '\' or not. (For example, If Source is "C:\AAA\BBB" and DestDir is "D:\CCC\", then Source becomes "D:\CCC\BBB" and DestDir becomes "C:\AAA\")
If Source has two or more files/directories, this menu item is disabled.
CTL+ALT+S is shortcut of this function.

(Only shortcut. FastCopy doesn't have any function for windows task scheduler)

7. Command Line

A basic format is as follows.

FastCopy.exe [/options] file1 file2 ... [/to=dest_dir]
