Bizarre issue - windows reporting incorrect drive space

[413x]

Windows explorer/computer

is reporting incorrect drive space free

I have about 50GB free, but explorer is saying i have just under 2GB free

even when saving a 4gb file, i get a warning on disk space
has anyone seen this issue?

 

[413x]

nope, doesnt seem to be

basically everything is telling me i have 1GB free, but i know i have deleted lots of stuff
also, windirstat says 83 used of 120..which makes much more sense
