Sorry master.

I am trying to delete files from: phonememory -Video Clips via the File manager that came with the N900. My N900 isn't connected to a PC I have no applications running the file in question is a film that doesn't work. A simple .avi file.

Any other questions?

@Mohammed, O crap, I have done both of those, my phone crashed so I took the battery out, I've also took the battery out without it being properly shutdown (got tired of waiting) and also I have just taken it out of the USB thing without it safetly removing it.

I'll keep that in mind, reckless noob alert. Lol.

I'll update you after I have done what you said mate.
