XLD4 (Graphic Data Document)
Unknownimage
XLD4 is a raster graphics format, sometimes known as Q4 file, associated with PC-98 a lineup of 16 and 32 bit computers manufactured by NEC in Japan. Each image consists of two separate files, one with a q4 extension and another with a q4d extension. The q4 file contains the bitmap image and the q4d the text description. In PRONOM these have been given two separate PUIDs.
