FileDeleteByAge with retention option

[Roland 1]

As an system administrator I have a lot of log, bak and tmp files. In most situations I want to clean up the oldest files, but retaining te last log files.

So I made a script wich looks at the age and number of files to be retained.

Example:

#include <file.au3>
#include <array.au3>
#include <date.au3>


Delete al files in TempDir with mask ~DF*.TMP minimum 24 hours old, but keeping 7 versions
_FileDeleteByAge(@TempDir, "~DF*.TMP", 24, 7)

Welcolme to the forums

It looks good, but i get an error if there is no files

: ==> Subscript used with non-Array variable.:

If $Files[0] > 0 Then

If $Files^ ERROR

->10:07:21 AutoIT3.exe ended.rc:1

So i modified script with a return @error and the number of files deleted.

Thanx for the adjustment. I didn't test it for No files.
