How to Handle Different File Extensions in a Loop When Renaming Files?

(0) ShareShare
ReportReport
Posted on by jgoldstein3 26

I encountered an issue by renaming files within a loop, I inadvertently removed their extensions. This became problematic as the loop iterates through various file types such as PDFs or Excel files. Could someone please advise on how to extract the file extension during the loop for each specific file, and then ensure it’s added back to the filename when renaming? I tried adding a split function within the renaming of the file name, but it came with an error. Any help or guidance would be appreciated. Thank you!

    @jgoldstein3  You can refer to this section of my latest YT Tutorial where I show you how to create a dynamic file name. At this point I show you how to extract the file extension. You can apply this concept to your flow. 

    Hope this helps!
