What software is leaving *_*_MVM_n.tmp files in my root directory?

Hi everyone:

I'm curious how to find what software could be leaving these files in the root of my drive D:? It's so annoying!

The Mondo Virtual Memory files are for the Mondo Framework that Adobe uses for certain operations in Photoshop, like the Liquify plug-in and perhaps writing a PNG file. If you have your TMP/TEMP environment variable set to C:\TEMP (the default location for TMP and TEMP are under your users folder) and have 10s if not 100s of gigs of freespace on C the files should go into C:\TEMP, but if there is not so much space available or the TMP folder points to somewhere complicated that the MF feels uncomfortable with, then it allocates those files on the root folder of various hard-drives, which can be a problem if some are on slow USB drives. They disappear when Liquify is closed if that's what created them, but I'm not sure about cleanup frequency from other operations. Files can have 0 bytes indicated in a directory listing but still have data written to them as long as they aren't closed or the buffered data hasn't been flushed to disk. They all might be created "just in case" you do something that uses lots of memory and could actually have zero bytes in them if you don't. Try using Liquify on a large image and see how large they become.

HTH :)

Oh wow. Thanks. So Adobe is messing with our systems again, hah? They literally think that they can pick an arbitrary drive and start writing to it. Amazing! Plainly amazing!

I don't use that Liquify thing, but I do use Photoshop.
