disk space - Ubuntu server slowly filling up

We had our Samba server (Ubuntu 8.04 LTS) share fill up the other day, but when I went to look at it I could't see any of the shares have too much on them.

We have 5 group shares and then each user has an individual share.

One user has 22 GB of stuff. A few others have 10-20 MB of stuff and everyone else's are empty.

So maybe like 26 GB total.

I deleted a few files yesterday and freed up about 250 MB of space.
Today when I checked it it was completely full again and I deleted some older files and freed up about 170 MB of stuff, but I can watch it slowly creep down in free space.

I keep running a df -h

What can I do to try to hunt down what's taking up so much of my HDD?
(I'm fairly new to Unix in general so I apologize if this is not well explained.)

After running a sudo du -sch * I got the following.

I noticed that Home is taking up 216 GB.

So I checked that out the home directory and there is a user that shows as 209 GB of data.

But when I run the du -sch * command from under his dir I get only 23 GB of data.

What am I missing?

Answer

It turned out there was a .recycler folder in each of the Samba user directories.

I didn't see them with a ls but I can see them with a ls -a.
