Nope, the search address (https://drive.google.com/drive/u/0/quota) you posted does not work fully... ok, it works yes BUT for some bizarre reason it leaves out many files so you may not get all the video files (or any video files with that search string, that's what happened to me).
First, determine whether your videos have a fixed abbreviation in the file name. For example, my phone camera takes videos and labels them as "VID_xxxxxxxx" where the xxxxxxxx is the date of filming the video. Like for example VID_20171101 is a video file I shot on January eleventh on 2017 (wow, I just used a time machine).
- Go to Drive
- Search: VID*
Now your Google Drive shows all the files starting with VID. Of course replace the search string "VID" with whatever your video files are labeled with.
