How to remove a file from an old iPad backup, still showing up in Finder
I purchased a new iPad Air to replace an older (vintage) iPad. I deleted all my personal information and took all that is necessary when an iPad (or other device) will be recycled. Of course I checked the iPad and as far as I could see, the iPad showed no personal files, photos, movies or what so ever. So I recycled it. After a while-maybe a couple of weeks later- I connected my iPad Air with my computer. To my surprise Finder showed a movie (perhaps from an older backup?) I once stored on the iPad to show to colleagues on a reunion. I absolutely don't want this file to be found on my iPad Air or Mac mini. This has nothing to do with secrecy or compromising material but some colleagues have passed away and it is more a matter of privacy of and respect for those people. Now my problem: Finder shows this:
I tried to remove the file but that doesn't work. Than I tried to restore the file from the (supposed) backup to my iPad Air and then to delete from there.
Finder shows me this:
Finder can't find the file, but in my view it must be "somewhere" otherwise how can Finder show it? I have looked at the iPad Air from left to right and top to bottom but no file with the name exists anywhere, so it must be hidden somewhere in the Macmini.
Any suggestions how I can proceed further? I don't have the original file anymore.
Please give me some hints, and as always: thanks a lot for your time and help.
