After adding the two files shown in the image I run an a "Analyze" with CCleaner and the second listed .dat file shows up on the to be deleted list and not the first one.
I guess something could be amiss with the first one as I can delete it manually and it is gone but when I use Super WinSpy and go to the location to open it it shows the file still there and still containing the same 113 files even though the size has actually dropped from 176kb to 64kb.
Have been messing with this all morning.
Appreciate any info.
