Shareware is not free. You can download shareware software for an
"evaluation period" to try it out and determine whether or not you want it.
Then you are asked to register and pay a determined fee for the program.
Information on product fees and registration are
usually included in a text file with your downloaded software.
It is illegal not to register shareware you plan on using. Registration of such software
is recommended. Reputable developers need the fees to continue
developing these relatively inexpensive programs. Some developers include
incentives to registering by including upgrades over a specified time period
and/or files not included in the downloaded shareware versions.
System disk
Normally PCs boot from the hard drive (C:). A system disk is a diskette, specially formated so that when this disk is placed in the A: drive of your PC it boots from the A: drive, allowing access to the PC without processing the C: drive first.

Upload
