I can't checkout, update, commit

[Joonseo]

Hi,

First of all, I am good at English. I am sorry to write with a translator.

I was using SVN and was not able to 'commit' due to capacity problems. So I want to 'checkout' all the folders to organize the folders. However, 'checkout' failed with the following error message.

Error: Couldn't perform atomic initialization  

Error: Can't find a temporary directory: Internal error.

It seems to be a capacity problem. So I tried to 'delete' a file but, the above message is displayed and it is not deleted either. How I can prove this problems? I need  your good reply.

Thank you.
