When you click on an icon to rename a file in the System 7 Finder, there is a small delay to prevent users from mistakenly renaming their files. In System 6, there was no delay, so that you could instantly rename files. Many users find this delay annoying since it slows them down. (This is certainly understandable since most users use computers to make them more productive, not less!)
With the System 7 Pack!, you can change this delay or even eliminate it entirely. The Rename Delay box contains a slider which you can use to change the rename delay. To turn it off, drag the slider down towards No Delay. Most users will either turn the delay off or leave it on, since it’s difficult to make distinctions between settings in the middle. Personally, I’ve turned the rename delay off on my Mac.
Removing System 6 Desktop:
When you upgrade to System 7, the Apple Installer does not remove the old System 6 desktop file. Since this file can take up a lot of space, many users would probably be better off deleting it. Select the Remove System 6 Desktop File menu item from the Control menu to delete this file.
The advantage to removing the file is obvious—you’ll save precious hard disk space. However, users that frequently switch between System 6 and System 7 will most likely want to keep the System 6 Desktop file on their disk. If they delete the Desktop file and then run System 6, they’ll have to wait for the System to rebuild the desktop again. There aren’t any harmful effects, but you’ll have to wait for the Finder to rebuild the very file that you just deleted.
Since I rarely use System 6, I’ve removed the System 6 Desktop file on my Mac. If you also rarely use System 6 or never use it at all, then you should probably do the same.
