Cannot delete ghost files
For some reason, I have noticed a lot of ghost files are on my Mac, which seem to arise after I move the real file to another folder or disk. This has happened often after I have carried out a search in the Finder and then move the resulting list of files. I cannot remember if these ghost files have been created in other situations but I suspect they have. These files are taking up substantial space and I am keen to get rid of them - there are hundreds of them and they are all .mp4 video files. I followed a procedure in another question on the same subject - Deleting ghost files - Apple Community - but when I tried to move the file to the Terminal window, the file just bounces back.
If you can help, please let me know asap.
The files I have looked at with the Get Info command all have current/recent dates (not 1984 or older).
I'd also like to know what is the cause of this anomaly.
