What ho one and all,

I downloaded on my XP computer, a great film (My Octopus Teacher) onto a USB stick and watched in on a W7 computer. Well worth seeing.

But now I want to delete it from the stick but cannot. It is listed in the directory with around a 4gb file size, but nothing I do will remove it. It no longer plays on the stick, all I get is a Corrupt file message. I have tired Move on Boot, plain vanilla delete, a command line, and it is still there.

The worst case is to copy everything and format the stick, but with around 50 gb of data, that is more than I want to do.
Any suggestions greatly appreciated.

Thanks and toodle pip
