Jonathan, Cygwin attempts to emulate Posix. Thus when it creates a file it also creates an ACL with the permissions for the owner, group and other (everyone). It does not pay attention to the inheritance of the directory, and it sets a bit in the file acl to prevent inheritance propagation, which is the Window default. In addition, if you are in the Administrators group, Cygwin will not set Administrators as the file owner (Windows default), but yourself. You could use getfacl, chown and setfacl to copy the acl, as follows (untested; make it a bat file) getfacl myfile > savedacl gzip myfile chown Admininistrators myfile.gz <== if you are in Administrators setfacl -f savedacl myfile.gz Even that won't be perfect. Everyone will still be in the final acl but with few access rights.
