Hello, I have recently found an unknown and bizarrely named folder on the root of my HD. ls -la lists it as: drwxr-xr-x 6 dan admin 204 Oct 27 21:17 9ffffffb200 It appears to be empty of files, but with three sub-directories in it. These are listed as: drwxr-xr-x 2 dan admin 68 Oct 4 21:56 -0effffff88ffffff-0000000000 drwxr-xr-x 2 dan admin 68 Oct 2 02:24 -0effffff88ffffff-d68102d3c1 drwxr-xr-x 2 dan admin 68 Oct 4 21:56 -0effffff88ffffff-de8102d3c1 They look like memory allocation addresses to me... Does anybody know what they are, and why they are there? Thanks!
