msgqueuedatafilemicrosoft files

[depro]

Hi there.
I'm having some problems with my "Storage" and "Programs" memories. Both are at 96% full right now which make my magician crash every now and then. Looking for files to delete I found several "MsgQueueDataFileMicrosoft" files on my windows directory. Does someone knows what they are used for? Can I delete them? Between them they steal 15MB storage memory!
Thanks.

in other threads i found only, that you can delete that files, but they come back soon automatically.
But i never looked after, if they really stole the amount of memory an explorer told they should?
Maybe they use the same memory-part?
