I have a 6th generation iPad, iPadOS 13.5
I have used an app called "On My iPad" that came preinstalled to this iPad to copy files to this iPad (like PDFs, movies, etc.). Eventually, I deleted all the files that I have copied (at least this is what I think I have done).
The problem is that there is still a lot of storage taken by something in this "On My iPad". Has it not completely deleted the files? How to clean up the storage?
Please see the screenshots.
When I look at the overall iPad storage I see that there is about 1GB taken by the "On My iPad". Also, there is a discrepancy in the reported available space. The "On My iPad" above shows that 20.31 GB available. The iPad Storage reports 14.3 of 32 GB used, i.e. only 17.7 GB is available.
Documents and Data
I have seen advice to delete an application and reinstall it back to reclaim the storage taken by the "Documents and Data" and I have done this trick successfully with the Keynote application. But there is no option to delete the "On My iPad" application and there is no such application in the App Store, so this method can't be used here.
