If you're a user of the Windows Zip-N-Go package, this short script will be of help if you're planning on doing any kind of testing or development. If you're hosting more than one site, just add a line for each site's directory following the pattern of the example.com zip-n-go default.

net stop apache2
del /F /S /Q C:\data\domains\example.com\www\public\uploads\temp\*.*
del /F /S /Q %windir%\Temp\Filecache\*.*
net start apache2
