What is "drv.mv" on a Windows computer?
In an (successful) effort to convert .mts HD video files to .mpeg format, I downloaded a freeware program from CNET called "Hamster Free Video Converter".
Using "Hamster Free", I tried converting a relatively large (85MB) HD file to MPEG, but the application appeared to hang, so I closed it. When I tried to delete the MPEG file (83% converted) saved as a result of this aborted process, I got the message:
"this action can't be completed because the file is open in drv.mv"
What is drv.mv?
The only thing that comes up is "drv.exe", which appears to be a worm of some kind. I use Microsoft Security Essentials, and all definitions are up to date. I did a "quick" scan, which found no issues.
The ".mv" filetype only appears to be associated with Unix/Linux.
I trusted that CNET will not knowingly point to software applications containing malicious code, and I also read 3 pages of reviews, which were all positive.
I don't generally download a lot of software, either.

I'd also guess a temp file.
Btw, for less hassle-filled video transcoding, try MPEG Streamclip. It's free, it's awesome, it just works.

Response by poster: NOD32 Online Scan found nothing. I'll try Malware Bytes, too. Thanks.
Thanks as well for MPEG Streamclip. HamsterFree is just...icky.

Best answer: Hamster is … well, possibly a bit dodgy. It's based on ffmeg.exe and mencoder.exe, but renames these two programs to drv.mv & drv2.mv for its internal use. Arguably, since Hamster is closed-source and these 2 programs are open source (licensed under the GPL), it violates the GPL.
(Note, I haven't looked into the issue of Hamster's GPL compliance any further than that. It's possible it's technically in compliance, but given that they try to hide the underlying GPL'd components like that, my guess is not. Certainly, it looks like it's against the spirit of the GPL.)
But, from your point of view, the upshot of this is that you aborted the Hamster program, but it left ffmpeg running in the background with your MPEG output file still open. If you kill the drv.mv process, or reboot, then you should be able to delete the MPEG file.

This thread is closed to new comments.
It could be that drv.mv is just a temporary file.. and rebooting would "release" the file lock.. but probably better to be safe than sorry.
