Macros
All directory names may contain macros that are expanded during synchronization. Begin and end of each macro is marked by a % character. Besides special macros handling time and date, the operating system's environment variables can also be used.
Internal macros
%time% e. g. 123044 format: [hhmmss]
%timestamp% e. g. 2012-12-22 123044 format: [YYYY-MM-DD hhmmss]
%year% e. g. 2012
%month% e. g. 12
%day% e. g. 22
%hour% e. g. 12
%min% e. g. 30
%sec% e. g. 44
%weekday% e. g. Monday (day of the week)
%week% e. g. 28 (calendar week)
Environment variables (Windows)
%AppData% e. g. C:\Users\<username>\AppData\Roaming
%ComputerName% e. g. Zenju-PC
%LocalAppData% e. g. C:\Users\<username>\AppData\Local
%ProgramData% e. g. C:\ProgramData
%ProgramFiles% e. g. C:\Program Files
%ProgramFiles(x86)% e. g. C:\Program Files (x86)
%Public% e. g. C:\Users\Public
%Temp% e. g. C:\Windows\Temp
%UserName% e. g. Zenju
%UserProfile% e. g. C:\Users\<username>
%WinDir% e. g. C:\Windows
Special folder locations (Windows)
%csidl_Downloads% e. g. C:\Users\<username>\Downloads
%csidl_Favorites% e. g. C:\Users\<username>\Favorites
%csidl_MyDocuments% e. g. C:\Users\<username>\Documents
%csidl_MyMusic% e. g. C:\Users\<username>\Music
%csidl_MyPictures% e. g. C:\Users\<username>\Pictures
%csidl_MyVideos% e. g. C:\Users\<username>\Videos
%csidl_Nethood% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Network Shortcuts
%csidl_Programs% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
%csidl_Quicklaunch% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch
%csidl_Resources% e. g. C:\Windows\Resources
%csidl_StartMenu% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu
%csidl_Startup% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\StartUp
%csidl_Templates% e. g. C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Templates
Note: Most macros listed here also have a variant for public folders. E.g. csidl_MyMusic → csidl_PublicMusic
Hint: You can add a great amount of flexibility to a ffs_batch configuration file by creating new temporary environment variables in a bat or cmd file that are evaluated by FreeFileSync at runtime.
Example: The FreeFileSync batch file C:\SyncJob.ffs_batch contains macro %MyVar% instead of an absolute target folder and is invoked by a cmd file:
"C:\Program files\FreeFileSync\FreeFileSync.exe" C:\SyncJob.ffs_batch
::%MyVar% is resolved as C:\Target during synchronization
Temporary environment variables created with the set command are only valid if the synchronization is started by calling the FreeFileSync executable directly. Using start /wait creates a new program context without these temporal variables.
