moderated free space issue questions

Juan Hernandez

HI All,


I know this isn’t fully a jaws help question, but I’m hoping someone in it or computer tech is experienced with this issue.


I have an ssd, which is my main windows 10 boot drive, it is around 475gb in total space.  Windows eexplorer says I got around 45 gb free.


Now, when I select all, and do a shift+f10, and click on properties, it updates and says that all of those files take up around 250gb.


I know that there are system folders/files that aren’t covered in that report, so I did a chkdsk, and my report is below:

Now, the summery at the end goes over my total space, I added all of the used items; and got


445764143 kb which is around 436gb


My issue is the above summery doesn’t account for the nearly 200gb that is not accounted for in the chkdsk summery, I can’t imagine that I have 200gb of files hidden etc.


Could someone please maybe give me some more pointers of where I can check?  And just for clearning things up I ran disk cleaner, got rid of all cashed files, recycle bin, etc. 


I hope some can bring some light to my issue.
