I put a USB in, and Vista makes a file like ABC12D.tmp

[ROTS]

I put a USB in, and Vista makes a file like ABC12D.tmp, or something along those lines. Doing a data recovery scan, I find this file is recoverable, but is immeditly

NOTE: I forget the name of the file, but it is a Tmp file, and usually have the words "emd" inside of it. When re-formatting my USB, the file was created.

I was reading and it say, this is an thumb image file???? where it collects information, when possible. I also assume this file, is responsible for the constant previewing of my images, and categorizing of files. Like stacking, by rating, things like that.

I do not want this file to be written to any of my hard drive or devices at all. I want these files to be shown up, so I can delete them.

I just want Vista, to stop writing this file, period. It is usually 0kb file, that writes once, and then delete itself, or make itself invisible???
