FCB Inspector 1.1 is a freeware Control Panel that allows users to
peek at a Macintosh's list of open files. It also provides information
about these files on demand and can close ones that aren't crucial to
system operation. Finally, when using System 6, it allows the maximum
number of open files to be changed. To install it under System 6.0x,
drag the FCB Inspector file icon into your System Folder and reboot.
To install it under System Software 7.0, drag the FCB Inspector file
icon over the System Folder icon and click OK to the dialog or drag it
directly into the Control Panels folder and reboot. FCB Inspector
provides balloon help in system 7.
