I have a Windows 10 desktop with a 1 TB drive that I use for my OS partition plus one other 500 MB partition (mounted as E:) that almost exclusively has junction links to folders on my other drives (these junctions do exist in directories created "locally" on the E:\ drive).
I have a program that automatically puts these junction links on the E:\ drive and this program recently started failing because it says it does not have sufficient space to create the local directories where the junctions will go.
When I look at the space usage with TreeSize Free (run as administrator to explore all folders), it says I am using 18.7 MB of space (this is almost entirely due to shortcut .lnk files I created on this "drive"). When I right-click on the E:\ drive in Windows Explorer and select "Properties" it says that I am using up 499 MB of space and only have 4 KB free (which I assume is correct due to the fact that I get an insufficient space error when I try to create a new directory here). Is all this space being used up in the file system table?
My Question: How can I examine where/how this half a gigabyte is being used?
I am on Windows 10 so I believe system restore is off by default but just to double check, I took ownership and gave myself permissions to look in "E:\system volume information" to make sure nothing was in there (and there was only 20 KB of files in that folder). Similarly I emptied the recycle bin just in case there was space being used there.
chkdsk gives the following output:
E:\>chkdsk E:
The type of the file system is NTFS.
Volume label is SsdLinkPoint.

So it looks like the bulk of the space is being use by "the system". Can I drill into that any further to determine how it is being used?
