Thanks Jeff. I'm using 5.2 still so I can't use that new
command. The spawn trick works in windows as well,
with no modifications necessary.

Here is what I do under Unix in IDL 5.1:
dir = '/the/directory/im/looking/for/'
; Create the directory, if necessary.
check = findfile( dir, count=direxists )
if (direxists eq 0) then spawn, 'mkdir '+dir
I am sure something equivalent can be done in Windows.
Jeff.

You can use the File_MkDir command that was introduced
in IDL 5.4.
Cheers,

If you have V5.4 you can use FILE_TEST( /DIR) to test if a directory
exists, and FILE_MKDIR to create a directory. If you have an earlier
IDL version you can try to CD to the directory and catch any errors (as
in http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/system/is_d ir.pro)
and SPAWN to create a directory.
