The problem is with uncompressing. The gunzip is located at c:/cygwin/bin/gunzip however, it is just a shell script, the content is: #!/bin/sh PATH=3D${GZIP_BINDIR-'/usr/bin'}:$PATH exec gzip -d "$@" So, it seems to me, dired of emacs on Windows is unable execute this unix shell script as is... any suggestion on getting emacs to call gzip -d directly? at this point, a easy practical solution is just to define the key Z in dired and hook it to my own function that parse file name to determine to compress or uncompress than call shell-command with gzip... modding dired elisp file seems will take much longer ... thanks for any thoughts.
