I try to create a little powershell script to rename multiple files named like babebibobu (ver.2.0).xlsx in a folder and subfolders.

I want to remove the (ver.X.X) from each filename.

I tried this one:

Get-ChildItem -Path "c:\test" -Recurse -Include "* (ver*.*).*" | 
    Rename-Item -NewName { $_.Name -replace " (ver*.*)","" }

but filename becomes babebibobu ().xlsx.

the -replace uses regex for evaluating what needs to be replaced. (...) defines a group not parenthesis characters, which need to be escaped.

Moreover, the regex inside the group is not so good.

Try this, based on a (ver.2.0) versioning :

Get-ChildItem -Path "c:\test" -Recurse -Include "* (ver*.*).*" |
    Rename-Item -NewName { $_.Name -replace "\s\(ver\.\d+\.\d+\)","" }

if you may have (ver 2.0) syntax, then the correct regex can be \s\((\.|\s)\d+\.\d+\)

\s for any space char and (\.|\s) is a group to say a dot (\.) or (|) any space char (\s)
\(and \) for escaped parenthesis

\d for any digit between 0 and 9 + for once or more this will include version or minor version > 10

\. escaped dot because you want a dot and not any character but line feed (. stands for any char but LF)

Be aware that regex are case sensitive, so \sand \d need to be lower case (upper case will be the opposite, all but space and all but digit)
