Renaming Filenames in Google Drive

[phlor01]

In uploading files into Google Drive, I choose to use the parameters of the sender name and the file name. Now the issue is, the file name has .pdf on it already, so when it is saved the .pdf is being duplicated. I want the new filename to be Sender_text before.pdf

May peace be upon you @phlor01

I think you can use the split function to split the filename .
