Directory size 135MB, but empty

Hi!
I backed up my e-mails from another server. E-mail count:903542, size > 2.2GB.
After I've removed all the unwanted e-mails from this directory, I copied the rest to my e-mail dir.
Now, the folder with my backed up e-mails is empty but directory size of /cur is still 118MB and /new 135MB.
But both directories seems to be empty. Output of

Code:

ls -l <path-to-maildir>

is

Code:

drwx------ 2 ntp    31 123453440 Jul  5 08:24 cur
-rw-r--r-- 1 ntp    31        31 Mai 16 00:19 maildirsize
drwx------ 2 ntp    31 141328384 Jul  5 14:35 new
drwx------ 2 ntp    31      4096 Mai 16 00:19 tmp

The output of

Code:

du -h --max-depth=1 <path-to-maildir>

returns

Code:

135M    /<path-to-maildir>/new
4,0K    /<path-to-maildir>/tmp
118M    /<path-to-maildir>/cur

The first command executed at the e.g. dir "/cur", returns "total 0".
Why is that and how can I fix that? Is it possible, that there are any files within the directories left which I can't see (I don't think so)?

Thanks!

 

Hi Till,
thnx for your reply.

It's not about the hidden maildir folders. It's about the stated size and their content.
An empty dir normally has size of approx. 4K. My e-mail folder "/cur" - as an example - doesn't have any e-mails in it but has a size of 125MB!
But: Your given command executed at the maildir "/cur", brought up this:

Code:

ls -la
total 120568
drwx------ 2 ntp 31 123453440 Jul  5 08:24 .
drwx------ 9 ntp 31      4096 Mai 16 00:19 ..

So, there are 120568 e-mails still left in this directory which I can't see.
Why is that and how can I fix that? Never ran into this before...
