Temp folder contains Scoped_Dir folders. My temp folder has only recently started filling up with Scoped_Dir..... Folders. I cannot located the program or service that is causing them. An internet search indicated the folders might be linked to Google chrome or steam but I don't think so.
FAT Root Folder. The root folder contains an entry for each file and folder on the root. The only difference between the root folder and other folders is that the root folder is on a specified location on the disk and has a fixed size (512 entries for a hard disk, number of entries on a floppy disk depends on the size of the disk). See Folder Structure topic for details about folder organization.
