DOS Batch or Command File to clean-up (delete/purge/archive) old BizTalk log/debug files

In a previous article, we discussed how to use a Powershell job to delete files over a certain age.

But what if if you want to do it using straight “pure” DOS .bat or .cmd file?  The following shows you how it’s done:

REM Cleanup all files more than 7 days old
cd E:\BizTalk\App\Backup
forfiles /S /M *.* /D -7 /C "cmd /c del @path"

NOTE however, UNC Paths are not supported. You CANNOT even specify UNC name to a remote server in the PATH parameter.

REM Cleanup all files more than 14 days old
forfiles /P \\server\BizTalk\App|Backup /S /M *.* /D -14 /C "cmd /c del @path"

The “forfiles” command is documented here, and
briefly recapped below:

It selects and executes any command on a file or set of files.


  • With forfiles, you can run a command on or pass arguments to multiple files. For example, you could run the type command on all files in a tree with the .txt file name extension. Or you could execute every batch file (*.bat) on drive C, with the file name “Myinput.txt” as the first argument.
  • With forfiles, you can do any of the following:
    • Select files by an absolute date or a relative date by using the /d parameter.
    • Build an archive tree of files by using variables such as @FSIZE and @FDATE.
    • Differentiate files from directories by using the @ISDIR variable.
    • Include special characters in the command line by using the hexadecimal code for the character, in 0xHH format (for example, 0x09 for a tab).
