What are .mst files?
Win7, Dell desktop, MSE
I was looking for some program in C:\ and in the list of programs, right after Windows portable devices and Windows sidebar, found a list of 11 items with names like 1029.mst, averaging about 120kb each, and with an icon that looks like a blank page of paper. It is always unpleasant to find something unknown in one's computer, and I can't find out what the mst extension could mean or what these files are doing in my computer.
The date associated with them is the same as for ABBYY PDF transformer, so I figure they are probably safe, but...
