Deleting files does not work, they only become invisible.
When I delete 40 gb of video files from Aloha they are no longer visible in the Aloha file manager but they still take up approximately 40 gb of storage space on my ipad. They are just renamed system files (or something). This seems to be a problem others encountered as well. To me it is a new phenomenon. It used to work fine. But now it risks bricking my ipad because I won't be able to update the ipados for lack of space. I have the latest ios. And I do not use the recycle bin, so I can't empty that.
