' NAME: PURGEFILES.vbs
'
' AUTHOR: Scott Weeks
' DATE: 10/31/2002
'
' COMMENT:PURGEFILES.vbs uses the LastModifiedDate of a file and deletes it
' if it is older that the specified number of days.
'
' USAGE: CScript.exe purgefiles.vbs <rootfolder> <maxdaysold> [/R] [/S] [/T] [/V]
' [/L:logfile] [/E]
'
' <rootfolder> - Specifies the directory to start purging files.
' <maxdaysold> - Specifies how old a file can be in Days before it is purged.
' [/E] - Report status and results to the Event Log.
' [/L:logfile] - Specifies a file to output the results to.
' [/R] - Deletes the rootfolder if it is empty.
' [/S] - Deletes any empty subdirectories.
' [/T] - Test Mode - does not delete any files or directories.
' [/V] - Verbose Mode - shows detailed information to the screen.
' /? - Displays USAGE message.
'
'====================
'Revision History:
'
'v1.2.1 - 11/06/02
'*Fixed* Script would not write anything to the logfile unless it was in TestMode.
'*Fixed* Potential problem that could delete the logfile if 0 maxdaysold was used.
'
'v1.2 - 11/04/02
'*Added* [/L] - LogFile option.
'*Added* [/E] - Event Log option.
'*Added* [/V] - Verbose Mode option.
'*Added* [/T] - Test Mode option.
'
'v1.1 - 11/01/02
