What is a compressed (ZIP/SIT) file
Files
are zipped, or compressed, for two basic reasons: to fit a number of files
into one space or to reduce one very large file to a smaller size. Compressed
files download faster and save storage space, but they must be decompressed
before you can use them.
Most compressed Windows files end with a ZIP file extension and
most compressed Mac files end in a SIT file extension, and these
compression formats are often not cross-platform compatible. For example,
AOL Windows software cannot generally decompress Macintosh SIT
files.
In most cases, you will not need additional software to compress or decompress
your files.
If you attach more than one file to e-mail you send, the AOL software will
automatically compress your files together into one ZIP file.
When you sign off, the AOL software will automatically decompress any ZIP
file you have downloaded, unless you have turned this feature off in your
download preferences. To find and download third-party software for other
compressing or decompressing needs, go to Keyword: Filesearch,
click Shareware, and search on the word "zip." You'll
find instructions for using these programs in the documentation that accompanies
them.
