How to delete a file not folder?

[eluser]allancaps[/eluser]
but is it really that? i mean, i have tried '/uploads/forum/', 'uploads/forum' and all others, but it doesn't seem to work. i have been able to upload to the folder, which suggests i can write to it, and i can delete from the db, but this I'm having trouble with... hmmm... are there any other settings that I might not have set? sorry for having all these questions... i have only been using CI for a month or so... but i'm loving it! thanks again.
