We are using CLM 4.x and I'm searching for an example how to prevent file / folder names that have problems on Unix / Windows systems (blanks / "/" / ...).

I tried a lot of expressions but nothing works fine. Are there any example ?

I suggest specifying a list of legal characters: ^[_0-9a-zA-Z\.]+$ in the 'Restrict Changes by Item Name' advisor. e.g:


With that predcondition enabled, I am able to deliver the creation of the file "TestFile.txt" but unable to deliver the creation of "!TestFile.txt".

I tried but with the setting "allowed" I am not able to upload a file with the name "TestFile.txt" and with the setting "prevented" every name (including special signs) is allowed.
Do you have an example that works ?

I've updated the answer to include a screenshot and mention that it properly allows the delivery of a file matching the regex and prevents the delivery of a file that doesn't match the regex.
