Overloaded with Extensions -- Teng Chou Ming has released the $10 shareware Extension Overload 2.7, a stand-alone DOCMaker document that provides information about 666 extensions, 245 control panels, Easter Eggs, Macintosh error codes, and more. It's smaller than, but otherwise quite similar to, Dan Frakes's InformINIT 8.1 (see "InformINIT: Your Personal Macintosh Informant" in TidBITS-429). Although there's obviously much overlap between the two, they provide complementary information in places. Extension Overload is a 227K download. [ACE]
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
