deleting users files

are files files server based?

Have you tried running Disk Cleanup using Task Scheduler?

Ok.  the del command didn't work in PS.  

So you can use the DEL in a batch file or you can use:

Get-ChildItem -Path C:\Temp -Include *.* -File -Recurse | foreach { $_.Delete()}

in PS.   I just tested the above command on Windows Server 2012 R2 and it work perfectly.  Deleted all of the file but left the folder structure intact.

they are servers based,

my objective: delete all files users would create throught the day, at the end of the day

and if was possible to create a batch or vbs so I can add it on the task scheduling...

Yes.  See my comments above.

If the files are not subject to Disk Cleanup (and it looks like no) , then the folders need to be known , delete with a batch file and use Task Scheduler to run the batch file.

Actually John, only the parent folder needs to be known.

Using the two solutions I provided, it doesn't matter what the sub folders are.  The commands I provided, will when run in a batch file, script, remove the files but leave the folder structure in place.

This way even if the users create their own sub-folders the files will be removed.  If it has to be done folder specific, then if they create a new folder that isn't part of the "known" group the files in those folders will be deleted as well.

hmm what If I need to apply it from a computerlist.txt?

Do you mean from a list of computers?

Just build your batch/script file with the specific computer names.

They aren't going to change that often are they?

Here's how to ping computers in a .txt file.

I'm sure you could modify the script to run the DEL command instead of PING.

thanks Scottcha, for giving me a clue

I ended up creating a script like this
del /S /Q "c:\Users\*.xlsx" >nul 2>&1

Anytime.
