Renaming folder with part of filename within the folder

I need to rename some folders (100+) with info contained in the filenames within that folder.

Each folder is a project folder that has the "project name" , but all the files within the respective folders have the corresponding "project id".

I want to update the folder name with the project id contained in the filenames.

How do I achieve this with ARen?

I would use the Move Batch mode to move the individual files into new folders based on the project id in the filenames. Then clean up by deleting the remaining empty folders.

Thanks for the reply.

The project files are already in their respective project folders. What I need to do is to update the parent folder with the project ID that is contained in the filenames.

I don't think that is possible. However, my solution will achieve exactly the same end result except that the original (now empty) project folders will remain and need to be deleted manually. However, if you specify the paths such that the new project folders are created in a new parent folder then you can simply clean up by deleting the old parent folder complete with the original project folders..
