Missing Capacity on Hard Drive

[PaulMc]

Hi I am new to the forum so hopefully this hasn't been answered elsewhere or isn't a newbies mistake.
I have a TS-212P with a pair of 2TB drives mirrored. I have been getting warnings about HDD being full so moved some files to another unit but noticed this didn't free up as much space as I thought. When I checked the Storage Manage it said I had 1.6TB in my multimedia folder but when I check in File Station it says there is only 42GB of files.
Have emptied every recycle bin that I could find and run a file check on the drives but still get the same mis-match.
What am I missing?

Try to push the refresh button with the two green arrows (on the far right) for the Multimedia shared folder.

The NAS does this refresh automatically nightly for all shared folders but changes made through the day will not be visible in the user interface until the next morning unless you do a manual refresh.

Thanks, tried that to no effect. Still same problem.
There is either some latency I can't overcome or there are hidden files I can get rid of.
Storage information for the folder gives 1.6Tb and about 15000 files while folder properties gives 42GB and about 6000 files.
Is it something about it being a shared folder?

...or there are hidden files I can get rid of.

Probably.

Is it something about it being a shared folder?

I can't think of a way that would affect this situation.

Have tried logging in as admin via SSH and looking around to see if you can find where the space is being taken up?

Its likely to be hidden directories full of thumbnails ".@__thumb" etc - the media options on the NAS generate these automatically. There are other options but as you are talking about your media folders its likely to be the culprit.

i had a directory structure of 500,000 photos go to almost 2,000,000 because of this. I have turned all the options off now - turning them off does not solve the problem - that's a manual task of deleting the mess!

You will only be able to see these directories (and there is one for every folder that has media in it!!) if you ssh in to your NAS - if you are not familiar with ssh then use something like winSCP (assuming you use windows)

Have a look around your nas and see if this is the problem if so then search on here and you will find several threads that have scripts to delete the hidden folders

If you don't turn the media options off they will come back over night!!!!

have fun

Thanks, I will turn of the media option and try to have a look.
Now I just need to brush up on ssh and scripts to delete hidden files

Search the forum, you'll find the info already posted, since I posted it (at least one poster about it).
