Disk Space Requirements User must have enough disk space available for receiving files. If the Disk becomes full during a file transfer, the connection is closed, file transfer is canceled, and all subsequent data is lost. The amount of free hard disk space required varies greatly with different users and depends on the average file size received. For example, an average text file or a spread sheet takes approximately 30 Kilobytes (30K) of disk space. Whereas, on the average, graphic files occupy 150K to 4000K of disk space. It is recommended that users have approximately 5000K (5 Megabytes) of free space available on the drive which the Focus TeleContact is installed. However, as mentioned previously this amount of free space may have to be increased or decreased depending on the average file size transferred to or from the user.
