What are compressed files?
Compressed files are files that have been recoded to remove extra space and
use less disk space than the expanded, usable version of the file. You cannot
use a compressed file until you expand it to its original format.
Files that contain text can often be compressed to less than half of their
uncompressed size.
You can also create a compressed file archive by compressing more than one
individual file into a single compressed file container. UnInstaller uses this
method of storing backup copies of files deleted by SpaceMaker and using the
PowerClean feature.
You use the same program to expand a compressed file as you used to
compress the file. There are many file compression programs available. One of
the best known compression programs for Windows is WinZip
®
, a shareware
program that is available from the Internet.
What is an autoexpanding compressed file?
An autoexpanding compressed file immediately expands all of the files that it
contains when you double-click the file name. The extension of an
autoexpanding compressed file is .EXE, just like the extension of an
application. These files are also called self-extracting compressed files.
When you create a compressed file archive, you can make it an autoexpanding
file. The file compression program adds executable code to the compressed
archive file, and this code is run to expand all of the files contained in the
archive.
The disadvantage of using an autoexpanding compressed file is that you
cannot select the files to be expanded, or the folders to which they are
expanded. The advantage of an autoexpanding compressed file is that you do
not need to have the file compression program on the computer where the files
are expanded.
Application installation programs that you download from the Internet are
usually autoexpanding compressed files.
