I have discovered a huge number of similar files in the root directory of my C drive. They all have names that start with "UDMFT" and end in 6 digits. The first one is 2,836,257 KB; and all the others are 1KB. There is no extension on any of them. I have looked at a couple of the smaller ones with Notepad, but they are unintelligible. They were all created on 1/18/2015.
The second thing I wanted to ask about is all the TEMP***ROOT folders in the root directory. The asterisks represent what mostly looks like filename extensions. Almost all of them were created in March of 2014. I think this was when we were cleaning malware from this laptop. I tried to find the topic, but couldn't. I hesitate to say who I think was helping me, because I'm not 100% sure.
Can I safely delete these Temp folders?
