There are these files with filenames beginning and ending with curly braces taking up too much space in my SSD main OS drive. They are located in the 'C:\Windows' directory. Could somebody please tell me what these are, and if they are safe to delete? I suspect something bad (virus perhaps), but I don't know for sure. There are other files like these, as shown in the screenshot below, but they don't take up as much space as these recent ones. Are they needed by the system? Are they from a bad program? I did some virus scan, but still nothing came up.
Those files are GUIDs. That they are displaying GUIDs instead of file names or folder names might be a bit of cause for concern. I would start with running sfc /scannow and chkdsk /r to look for file system corruption or corruption in the system files.
Thanks for trying to help me with this alarming 'problem'. I checked using sfc and chkdsk, both found nothing (chkdsk log from Event Viewer included for reference). Should I delete them? I don't think I could recover data from them, or maybe I could?
Chkdsk was executed in scan mode on a volume snapshot.
