How to specify the folder for temporary data files ?

[batmax2]

Sometimes there is not enough room on the system drive where temporary files created by default. Does anybody know how to specify my own folder for those temporary data files ?

Well, I've found two ways:
1) specify the environment variable MAGICK_TEMPDIR
2) specify the path for temporary files "in-line" like this:
convert -set registry:temporary-path /data/tmp...

Those two ways definitely dont work under Windows (and I didn't test under Linux).
In Windows, IM stores it's temporary files where the system variable "TMP" (but not "TEMP"!) dictates.
In Registry that variable is stored at:
HKEY_Current_User\Environment\TMP
Works under WinXP Pro SP2 at least, may be on other windozes too.
