Nevermind, it's not a cygwin problem. Sorry :(
=== So let’s say I’m at a cygwin bash prompt and I… cd /cygdrive/c/backup mkdir test (I’ve set my umask to be 000) The dir “test” can not be deleted from windows. All security permissions would indicate that it is delete-able. There are NO handles open to the directory that Process Explorer can find. The dir will delete fine from within cygwin. I have admin rights on the PC. The problem doesn’t happen to files, just directories. If I do this: cd ~ (to go to /home/myaccountname) mkdir test This “test” directory can be deleted from windows, no problem. I’m completely stumped and baffled. I just got the new cygwin dll 1.7.3-1 and this is a fresh “base + rsync only” install on a winXPpro x86 PC.
