If you have students that have a lot of image or video files that they need to rename, this tool is for you. I recently had a teacher contact me about the issue of working on the school yearbook. She has a ton of image files in a folder and needed to quickly rename these items so that she could better organize them into folders and better scan through her files. By using the Bulk Renamer for Google Drive, you can choose a part of a file's name and replace it with your own custom text.
There is a basic and advanced feature. I just used the basic function to replace portions of file names. You can get much more detailed with your bulk renaming with the advanced features, but this video should at least get you started.
