A User of Multiple File Rename for Google Drive
Basic app that is suitable for basic bulk renaming of files, however, it would be great to see some more complex functionality if possible.
It seems to work well in general but I have noticed some strange behaviour when changing photo file names and then uploading them Google Photo using the Upload from Google Drive feature on https://photos.google.com/. After they upload, the filename (when viewed on Google Photos) shown is the old filename (the new filename still shows in Drive). Not sure if this is a problem with the extension or Google Drive or Google Photos.
