I have just updated to win 10. all looks good except I am unable to access my data files from win 8.1.
The data was in c:\data and backed up to E:\data and to a thumb drive which shows as G:\data.
File Explorer hangs when asking for the properties of C:\ or sub directories.
It can not display file contents of any of the data files. Explorer reports "Working on it."
Please help, this represents years of active and historical data!
