I am not able to import my Aptana project into Zend Studio 7 because it is inside the folder /usr/local/ on my machine (Macintosh OSX), which is technically a hidden folder.
Although I have hidden files and folders visible in Finder, Zend's file browser does not show them.
I did find one Zend Studio setting under Preferences>Remote Systems>Files that allows you to "Show hidden files". But, guess what! That doesn't do diddlysquat for folders!
The solution that I am going to pursue is to move my project into the Sites folder, which is not hidden.
