Hi there.

I've got this situation when image converting :

[mtr@mts8 tmp]$ ls -alh
total 8.8G
drwxrwxrwt 8 root root 4.0K Jun 30 08:26 .
drwxr-xr-x 33 root root 4.0K Jun 17 00:45 ..
drwxrwxrwt 2 root root 4.0K Jun 17 00:45 .ICE-unix

drwxr-xr-x 2 root root 4.0K Nov 26 2007 agent
drwxr-xr-x 2 mtr mtr 4.0K Jun 26 10:21 hsperfdata_mtr
drwx------ 2 root root 4.0K Jan 15 14:55 keyring-eEzCAk
-rw------- 1 mtr mtr 23G Jun 30 08:26 magick-XXEZfZ4m
srwxr-xr-x 1 root root 0 Apr 8 15:28 mapping-root
[mtr@mts8 tmp]$ pwd
/tmp

'mtr' is account using IM converting Lib.
Can you tell me what is that file? : magick-XXXXXXXX
I wonder that what is an aim for this file and where is recorded place(source level)for this file.

thanks.

It is a temporary file IM created for some purpose. If you no longer have IM running it can be deleted. They can sometimes be left behind if Im is abnormally aborted.

You can also specify what 'tmp' directory IM should use using various environment variables. See 'resources' on the main IM website.
