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 off
setlocal
if \{%3\}
\{\} goto Syntax
set folder=%1#
set folder=%folder:"=%
set folder=%folder:\#=%
set folder=%folder:#=%
if not exist "%folder%\*.*" goto Syntax
