The program displays the following message at Start-Up, then shuts down:

Warning. Insufficient Disk Space To Run This Program

Simple Accounting checks for at least 1 MEG of free disk space before starting. The program doesn’t actually require that much free disk space to begin; this safety feature is included in order to avoid any possibility of running out of space while processing transactions. To correct the problem, erase old files from your hard disk to free up more space. Do not delete any files from your Simple Accounting directory.
