Can't delete file from USB memory stick

[highstream]

XP/SP3. Have a 300mb .avi file on 2gb stick that I copied onto it and watched last night. Now, when I try to delete it in Win Explorer, the file at first disappears as if it was deleted, but upon refresh it's still there. Try to delete again and thereafter get access denied error. Since the stick was inserted into the computer on start up, I wondered if somehow that might have caused the problem. But upon reboot, get the same sequence. Any ideas? Thanks.

Update: Rebooted to Safe Mode and file wasn't there. Tried deleting another file and got same problem. Tried re-formatting stick and got error message that it was being used by other programs. Then rebooted computer to normal mode and second file deleted as normal. Odd.

Sometimes this can be caused by video codecs behaving badly reading meta data from multimedia files such as AVI's etc. You could possibly use Sysinternals Process Explorer to find the process locking/accessing the file.

Next time you get a locked file problem/error, try the FREE utility Unlocker.

Doc Watson, your program works but MSE sees it as carrying a Trojan: TrojanClicker:Win32/Yabector.B. It's probably not, tho: http://www.microsoft.com/security/po...2%2FYabector.B. Could it be the eBay add on?

I've never heard of this utility being "loaded" from the creators site I linked you to, or anywhere else for that matter. That said, it does sound like a false positive.

What eBay add on ?? This is a small, stand alone utility. Is the eBay add on on your PC or did it come with the Unlocker download ??

I just checked the creators blog and he addresses this issue there. Check it out here.

Thanks for the link. As you could probably tell from the creators blog, the eBay add on is part of the install package (as is listing Unlocker in the Win Explorer right-click menu). I'll report the false positive with the link to MSE.

I guess I never noticed the eBay add-on before and didn't look for it this time.

I NEVER install anything that piggybacks on a program or utility I am installing. I always opt out of the "extras" and if I can't, I bail out of the installation.

They call them Personal Computers for a reason.

I don't install those things either, and unchecked the eBay one. However, it appears to be the very presence of the code in the installer and installed program that's getting the reaction.

Did you follow my previous link to the creator's blog, where he addresses the issue of false positives ??
