In perusing my Mac I find an Application Support file in my .Library and another in my .users/aljones/Library. In some instances the same application appears in both folders albet 2 different versions and/or creation dates. Since I am the only user on this machine can the 2 application support folders be combined and the older versions then deleted, or can I just delete the older applications regardless of which folder it is in, leaving everything else alone. Thanks Al
