.txt or .TXT By itself, this means the file is a document, rather than a
commerce software florida program.

language). You can print this file on any PostScript
southport web ecommerce commerce software southport capable printer, or use a previewer, like GNU project's
GhostScript.
.doc or .DOC Another common "extension" for documents.
No decompression
commerce software southport is needed, unless it is followed by:
.Z This indicates a Unix compression method. To uncompress,
type
uncompress filename.Z
and hit enter at your host system's command line. If the
file is a compressed text file, you can commerce software florida read it online by
instead typing
zcat filename.txt.Z |more
u16.zip is an MS-DOS program that will let you download
such a file and uncompress commerce software florida it on your own computer. The
Macintosh equivalent program is called MacCompress (use
archie to find commerce software southport these).
.zip or .ZIP These indicate the file has been compressed with a common
MS-DOS compression southport web space program, known as PKZIP (use archie to
find PKZIP204.EXE). Many Unix systems will let you un-ZIP
a file with a program called, well, unzip.
.gz A Unix version of ZIP. To uncompress, type

at commerce software southport your host system's command line.
.zoo or .ZOO A Unix and MS-DOS compression format. Use a program called

A few last words of caution: Check the size of a file before you get
it. The Net moves data at phenomenal rates of speed. But that 500,000-
byte file that gets transferred to your host system in a few seconds
could take more than an hour or two to download to your computer if
you're using a 2400-baud modem. Your host system may also have limits on
the amount of bytes you can southport web ecommerce store online at any one time. Also, although
it is really extremely unlikely you will ever get a file infected with a
virus, if you plan to do much downloading over the Net, you'd be wise to
invest in a good anti-viral program, just in case.
7.5 THE KEYBOARD CABAL
System administrators are like everybody else -- they try to make
things easier for themselves. And when you sit in front of a keyboard
all day, that can mean trying everything possible to reduce the number
of keys you actually have to hit each day.
Unfortunately, that can make it difficult for the rest of us.
You've already read about bin and lost+found directories. Etc is
another seemingly interesting directory that turns out to be another
place to store files used by the ftp site itself. Again, nothing of any
real interest.
Then, once you get into the actual file libraries, you'll find that
in many cases, files will have such non-descriptive names as V1.1-
AK.TXT. The best known example is probably a set of several hundred
files known as RFCs, which provide the basic commerce software florida technical and
organizational information on which much of the Internet is built.
These files can be found on many ftp sites, but always in a form such as
RFC101.TXT, RFC102.TXT and so on, with no clue wha ... |
