B4J Question Batch rename file?

[tsteward]

I have downloaded digital files from my opencart server and they all have random extensions.
I need to be able to

• Chooser a directory.
• Lists all files in that directory.
• Renames each file by removing anything after .pdf (keeping the .pdf extension only).

Can anyone help with this. I had a go and it sounds simple but I failed

Hoping someone would be kind enough to knock up a quickie for me PLEASE!

In case this was a one-off, and you have access to Linux:

To delete everything after "pdf" in a file name in Linux, you can use the rename command with a regular expression. For example, the command...

rename 's/(.*\.pdf).*/$1/' *.pdf

...will rename all PDF files by keeping only the part before any additional characters after "pdf".

That's cool, but in windows?

No idea. Perhaps just ask ChatGPT?

In Windows, how to delete everything after pdf in file name?

powershell

Get-ChildItem -File | Where-Object Name -match '\.pdf\.' | ForEach-Object {
$newName = ($_.Name -replace '^(.+?\.pdf)\..*$', '$1')
Rename-Item $_.FullName -NewName $newname
}

PowerShell truly is like poetry.
