Massdelete files

Not sure what happened, but thousands of small files piled up in the path below.

C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-8

My google-fu wasn’t sufficient enough to find out what files in that folder actually did. An article from Kofax said that just deleting files could be troublesome. But also found another article that stated that he deleted all files older than 30 days and hasn’t had problems yet. So I dare to do the same. The command was found on a blog, so all credit goes to this guy.

forfiles /D -30 /C "cmd /C attrib -s @file & echo @file & del @file"

forfiles is a very nice command that iterates through the files in a folder according to its parameters. /D -30 iterates through all files more than 10 days old. attrib -s takes off the System attribute, which is needed for DEL to work. The echo is there so you can see that it is doing its job.

The PowerShell equivalent would be:

Get-ChildItem -Path C:\programdata\Microsoft\Crypto\rsa\S-1-5-18 -Include *.* -Recurse | foreach { $_.Delete()}
