Just a quick reply,as I have HUGE fish to fry ATM
WinDirStat works here on W7 only ever 64 bit (never used 10 yet) and if one fills in ALL the colours of the VISUAL approximation of a HDD/SSD whatever,like me,you may (?) find a 500GB drive (all Iv'e been using since...) to be 3 times more STUFF ,i.e. 1.5 TB,and windirstat (Free) may?,though i'm unable to totally verify BACKUPS,the .dll you need,as far as FIXING,again?

Also THAT freeware has a SHOW IN Explorer right click option so....
