For now I exclued files named 'DICOMDIR', but I'm not sure that will always be the full name of these files. Any idea why QUERY_DICOM crashes on DICOMDIR or how I can avoid it in a more robust way than filename-match?

Hi. I looked at help of Query_dicom. So Query_dicom is wrote IDL and placed in IDL LIB folder. There are some comments in IDL code. I put here the fragment

;; verify that the file exists
IF ~file_test(file) THEN return, 0l

;; DICOM has a fatal error in accessing zero-length files
;; Avoid the problem by checking in advance
OPENR, unit, file, /get_lun
stat = FSTAT(unit)
FREE_LUN, unit
IF (stat.size EQ 0) THEN RETURN, 0L

So DICOM has a fatal error in accessing zero-length files, may be it's your case ?
