I have scripted Purge.bat to delete files in a specified folder whose last written date falls within a given date range.

The syntax for using Purge.bat is:

purge Folder From_YYYYMMDD To_YYYYMMDD [/S]

Where:

Folder        is the path to the folder you want to purge.From_YYYYMMDD is the lower date in the range, using YYYYMMDD format.To_YYYYMMDD   is the upper date in the range, using YYYYMMDD format./S            is an optional parameter that also purges matching files in all sub-folders.

Purge.bat contains:

@echo offsetlocalif {%3}

{} goto Syntaxset folder=%1#set folder=%folder:"=%set folder=%folder:#=%set folder=%folder:#=%if not exist "%folder%*.*" goto Syntaxset fromdt=%2set todt=%3if "%fromdt%" GTR "%todt%" goto Syntaxif "%fromdt:~7,1%" EQU "" goto Syntaxif "%todt:~7,1%" EQU "" goto Syntaxif "%fromdt:~8,1%" NEQ "" goto Syntaxif "%todt:~8,1%" NEQ "" goto Syntaxset xx=if {%4}
