How to know free space in the DVR?

Hello!
Is it possible to know the free space of the hard disk on the IP registrars DAHUA? Specifically on the model of DHI-NVR4216-4KS2. He found no such item in menu.

Free volume disk recorders, because the record is cyclical. At the beginning of the logger formats the screw under its own file system and starts recording according to settings. The disk fills some time, and then just the oldest entries are overwritten with newer.
PS the manual is not found, but this is usually the system partition and data on the HDD.
Leonid, thanks for the reply.
I saw that system shows only the total amount of my disk. Was hoping can like it now to see how many of the total is video, to determine the need for more disk storage records. - urban56 commented on June 8th 19 at 10:32
Usually writes something like Used/Available 980 GB/1024 GB, and this does not change full memory usage.
This is done a bit wrong. Google calculator video for IP camera https://markevich.by/raschet-videoarxiva-propuskno... and is considered to be.
It is necessary to know the stream from the cameras, image resolution, number of cameras, codecs, % movement, etc.
Or empirically:
Know the amount of hard and the number of cameras, look at the date of the earliest entry date and latest.
10 cameras, 10 days is a 10 GB drive - so 1 day they occupy 1 GB. Each camera per day is 100 MB. Means to record 20 days we need the disk to 20 GB. - delores_Eichmann commented on June 8th 19 at 10:35
