Introduction
Sweeper is designed as a behind-the-scenes utility, it’s function to free valuable space on your floppy and hard disks (Sweeper doesn't do anything with CD's or other read-only media). Sweeper can also speed up floppy disk access time, usually by around 50%. It does this by deleting a special database used only by the Finder called the Desktop Database. This database resides on any Macintosh disk and is used to store the icons and document-to-application program links of all items on a disk. Before a disk appears on your desktop, Sweeper checks the database's age and deletes it if it's older than the number of days set in the control panel. On a floppy disk Sweeper then rebuilds the database from scratch before returning control, on a hard disk the Finder rebuilds the database.
What’s the point in doing this? When you delete, copy, or rename files on a disk, the Finder does not remove the file’s old information from the Desktop Database and thus the database gets larger and larger. After some use the database can be much larger than it should be. On a floppy disk this can be around 100K of disk space wasted. And the larger the Desktop Database the longer the Finder takes to open it.
Using Sweeper you can improve the performance of your disks and use all of the space to the maximum.
• Please note: you can still use the Command-Option key shortcut to rebuild the desktop database at any time (see the Finder Shortcuts on the Help Menu).
System requirements
This version of Sweeper will work on any Macintosh with a 68020 processor or better (Macintosh Classic II, Performa 200 or PowerBook 145 or better) running System 7.1 or greater, or any Power Macintosh, Performa or PowerBook running System 7.1 or greater.
This version of Sweeper will not work on the Macintosh 512K, Plus, Classic or PowerBook 100 and will not work on any Macintosh running System 7.01 or less.
Before installation
If you want to see how effectively Sweeper works, put a frequently used floppy disk in your disk drive before installing Sweeper and note the 'K in disk' and 'K available' figures at the top of the disk's window. Then install Sweeper exactly as under 'Installation' below. Press and hold down the option key and insert the disk used before installing. You should see the wristwatch cursor and hear the sweep sound if checked in the Control Panel and after a few seconds see the disk appear on the desktop. Note the difference between the 'K in disk' and 'K available' figures from before. I hope you are impressed!
Installation
Double-click on the Sweeper Installer. When loaded the Installer will tell you exactly where Sweeper will be installed on your startup disk (usually your internal hard disk). Then just click on the Install button. After installation, restart your Macintosh to activate Sweeper.
Using the Control Panel
• Use the 'On' and 'Off' buttons to turn Sweeper on or off at any time. Sweeper is always loaded at startup.
• The number of days between sweeps on a disk is displayed in the 'days' edit box. You can type a zero in this box to always Sweep disks (same as holding down the option key).
• When 'Startup Disk Only' is on Sweeper will only work on the startup disk (usually your internal hard disk).
• When 'Any Disk' is on Sweeper will work on any disk.
• When 'Always sweep when option key is down' is checked Sweeper will immediately sweep any disk when you insert it while holding down the option key.
• When 'Sweep Sound' is checked Sweeper will play a 'sweep' sound after sweeping a disk.
You can also use Balloon Help to learn about each item.
For registered users, click the 'Advanced' button for two additional options:
• 'Additional control over the startup disk' allows you to specify a different sweep pattern for your startup disk.
• When 'Reserve memory for Sweeper at System startup' is checked, 66K of the System Software's memory is reserved for Sweeper at startup time.

And finally…
I enjoy writing Macintosh programs and only your registration fees will keep the lights on late at night. At present (27th August 1997) I am working on a new (secret) idea. I hope to have my new program out in October 1997.
