FAT32 drives will have Windows erroneously give that message if you copy a file bigger than 4GB to said drive.
The mystery to me is why Microsoft never corrected the error message.
There's also a problem if you place a lot of files in the top folder or "root".
Again, Microsoft issues a drive full message even when it's just the root directory has run out of space.
-> What do you think Josh, shouldn't Microsoft have corrected these errors given it's been over a decade?
I have a second hard drive on my windows 7 pc, i've been using this to back up my main hard drive (currently using acronis). However, it seems to suggest that the hard drive is full even when it is not. The main files and folders only seem to total around 40Gb and the hidden files and folders another 20Gb. There seems to be another 140+Gb of storage space missing and i cannot work this out. I thought it may have something to do with acrnois live back up system however, i'm not sure. Any information on where this storage space is being used would be great.
