enfuse is honest

enfuse: cannot process "a0.gmz"; not recognized as an image
enfuse: info: possible causes:
enfuse: info: - An underlying image-processing library does not understand the
enfuse: info:   particular compression, sub-format, format extension, ...
enfuse: info: - Enfuse was not compiled with support for this format, which
enfuse: info:   can be checked with "enfuse --show-image-formats".
enfuse: info: - The image is corrupted or it is incomplete/truncated.
enfuse: info: - It really is not an image.  Honesty, huh?

In case you were wondering, gmz is a G’MIC format.


Is there any other program other than gmic that can read this files?

Just a typo: wasn’t expecting enfuse to recognize it.
