My hard drive states it is full last month it was not even close. I have transfer folders and files to external drive and very little space removed. I had this problem before and I think it had something to do with Sage 50. My drive looked full and then everything was back to normal. Any suggestions?
The best two tools for Visualising where your storage space is being consumed are TreeSize ( https://www.jam-software.com/freeware/ ) and WinDirStat ( https://windirstat.net/ )
I have used both, they both do the job, but i prefer WinDirStat's UI
