This question already has an answer here:
A few days ago, my TexStudio (which I have used without difficulty for years) started being slow compiling, not compiling when I hit the "build and view" and "build buttons", and saving these strange extra files when it finally does go through. Again, these are not the usual extra files, like the ".aux" file. They look like maybe they are failed save attempts. It is doing this for every project I work on, even old ones I pull up that have pretty different preambles. Here are examples:
Cover Letter Template 1.tex.b10756
Cover Letter Template 1.tex.r10756
Anyone know what has gone wrong, and how I can fix it? I've had no luck searching for other people having this problem, or from any other help source.
