USB Disk SE, File Manager

I was trying to play a audio but the volume kept glitching and the audio wont play can someone tell me why???

I was hoping to use this app to help my quickly transfer files from my SD cards (I work in video production) to a hard drive while I travel. I attempted to copy a folder from the SD card to my hard drive. However, the files didn’t fully transfer from the folder. So I figured I’d delete the copied folder and tried again. Doing so for some reason deleted the original folder as well. And when I went to the trash bin in both the app and my iPad’s trash bin, the files could not be found. Thankfully I was just testing the app and the deleted files were just some personal photos from a trip. But I would be livid if it were my client work. I wouldn’t trust this app with any professional work.

The IOS Files app can longer works with Google Drive as it results in an “authentication needed” error. I finally found and app that can connect Google Drive to the USB portable drive connected to my iPad. It won’t let me upload directories, but I was able to hit “select all” and start uploading files. The problem is that it uploads 5-7 files then just stops. No explanation. Waited for a half hour, nothing further has happened. Eventually, I got pop up that said the files that I was trying to move over don’t exist. Went through this process several times and gave up.
