015- What do the different popular file name extensions,
like ".BSC", mean; and, how do I access the files?
File name extensions tell you what sort of file you are dealing with so
that you will know which program(s) to use to unpack, unShrink, display, etc.
the file. Many programs which create such files do not automatically add an
extension-- for example, most of the disk images on the Golden Orchard CD are
Diskcopy files with no name extension. Many other programs which create files
suggest a default extension as part of the name-- GS-ShrinkIt generally suggests
".SHK"-- but, the user can change this and
save under any legal name desired. (One popular change is using ".SDK" for
ShrinkIt whole-disk archive files.)
Some extensions indicate a filetype recognized by Apple II ProDOS; but,
often, the extension is just for user information or to help some utility
recognize the file as one it can deal with. For such files the actual ProDOS
filetype is usually TXT, BIN, or SHK.
