prefixing all files in multiple folders
I have several folder (35 to be exact), each folder contains 10-12 sub-folders and each sub folder about 20 files.
I want to prefix each file with the name of the sub-folder but the only command I found is for renaming only one folder at a time :
dir | Rename-Item -NewName {$_.Directory.Name + " - " + $_.Name}
Is there a way to loop through all the folder ? (I'm not used to Powershell)

Yes, there is, and it is detailed in the PowerShell Help files. That is what the -recurse parameter is for.

Yet what you are doing in your code, is renaming the directory only, not the files in that directory or sub-directories. You have also not specified and start directory, so it will take action on whatever directory you are currently in vs the one you may want.
You need to loop all directors and loop all the files in those directories, to rename the files in that passed in the directory.
Update as per my '-WhatIf' comment
Just another way of doing what 'marzse' gave you, just with notification of what's being processed, and a check. Remove the -Whatif, if things look good, and run it again. Never ruin anyone's code if you are ae not absolutely sure what it is doing, or you are willing to accept the consequences of doing so.

Never rush into code or do all things at once. step in to in one step at a time to make sure you are getting what you'd expect at each step.
To get to the above, this is what I mean. Logical full step-thru, then once you understand you can optimize to what marsze shows.

Use the -Recurse switch to get items from subfolders too. Additionally you can also use the -File switch to return files only:
(dir -File -Recurse) | Rename-Item -NewName {$_.Directory.Name + " - " + $_.Name}
Note: As @postanote pointed out, it's always recommendable to test destructive commands first using the -WhatIf switch.
