my iso game was working fine then it stopped working so i decided to delete it but it kept coming back and the size was 0kb but still was taking space on my memory card. I was wondering how to delete this corrupted file?

..sorry if this is the wrong forum to ask

Delete it from your computer or format your memory card.

I've had that problem a few times too. What I do is go to "My Computer", right click the PSP's drive and run an error check. (Under properties, tools, error-checking) After I perform that, it allows me to delete the file.
