I've been given shared access to a Google Drive folder that contains a large number of subfolder and files. Most of this is electrotechnical documentation.
However there's so much to read and not all files have easy-to-remember names. I'm looking for a way to mark which files I have viewed/read and the ones I haven't. Especially since a lot of new files will be added in the future. Also marking the most important files for future reference would be very useful.
A functionality that's native to Google Mail but seems absent on drive.
(files will mostly be pdf/word/excel)
edit:Simply "tagging" the files with soms keywords would also be okay if they're easy to view in the folders without having to open each file seperately.
