Wd dx4000 drive c: is full (the Os drive)

Is it possible to expand the c: drive is now 60gb there is a lot of space on de the d: drive free

Some folks have used 3rd party tools.  I would practice with whatever on a box with a monitor.  You might also get a tool like windirstat to see what is using the space.  I still have 20gb free after years of updates

I find out that the temp folder was full with 27gb clear that and there was space again


Glad you found out what was filling up the drive.

You can also check the storage locations of the shares in the Dashboard. I’ve had a few cases where the folders were storing data on the C: drive instead of the D: drive. There is an option to “Move” the folders in the Dashboard if they are storing to the C.
