I dont know how many people has this annoying problem with Windows XP but let me explain it here... maybe it's only happening to me. Ok to make it sound simple here I will make an example: I downloaded a movie or mp3 with a program, finished the download and closed the program, trying to delete the movie/mp3 file and it tells me "It's being used by another person or program". That happens to me all the time and sometime after I restart my computer I still can't delete the file. I have all default setting on XP so I'm not sharing anything through the Network.
What the heck is going on?

this is a bug of XP windows explorer, as far as I understand from it..
and the problem is particularly with big files like avi, mpegs or mp3s.. and made worse if the avi is a broken download..
if u wait long enough after u select the file.. (lookout for the harddisk indicator lights to stop flashing).. then u can delete it after that.. weird huh?
the problem with is confirmed to be winXP explorer, because inside winxp, as long as u dun access the files from explorer, by going into the command prompt, u can actually just delete it straightaway without such waits..
it's a problem which I am still waiting for a solution still..

cheers, hopefully it will be fixed by the XP service pack 1
