I recently posted a script for removing unnecessary files and pruning files based on their age, which can be used at logoff to keep profile sizes manageable - Reducing Profile Size with a Profile Clean Up Script.
Andrew Morgan (@andyjmorgan) has kindly translated my very basic VBscript to PowerShell. This can be used as a standalone script or the function (remove-itembyage) could be integrated into your own scripts and has the added benefit of in-built help and the ability to run silently.
Just like the original script, this could be executed at logoff, before the profile is saved back to the network, to perform two actions:
- Delete all files of a specific file type in a specified folder, including sub-folders
- Delete all files older than X days in a specified folder, including sub-folders
For example, you could use the script to delete all .log or temporary files below %APPDATA% that aren’t required to be roamed, or delete all Cookies older than 90 days to keep the Cookies folder to a manageable size.
Note: the script listing below has the -whatif parameter applied when calling the function, so no deletes will occur unless the parameter is removed.
function remove-itembyage{
<#
.SYNOPSIS
remove items from folders recursively.
.DESCRIPTION
this function removes items older than a specified age from the target folder
.PARAMETER Days
Specifies the ammount of days since the file was last written to you wish to filter on.
.PARAMETER Path
Specifies the path to the folder you wish to search recursively.
.PARAMETER Silent
Instructs the function not to return any output.
.EXAMPLE
PS C:\> remove-itembyage -days 0 -path $recent
This command searches the $recent directory, for any files, then deletes them.
.EXAMPLE
PS C:\> remove-itembyage -days 5 -path $recent
This command searches the $recent directory, for files older than 5 days, then deletes them.
.EXAMPLE
PS C:\> remove-itembyage -days 10 -path $appdata -typefilter "txt,log"
This command searches the $cookies directory, for files older than 10 days and end with txt or log extensions, then deletes them.
.EXAMPLE
PS C:\> remove-itembyage -days 10 -path $cookies -typefilter "txt,log" -silent
This command searches the $cookies directory, for files older than 10 days and end with txt or log extensions, then deletes them without a report.
