If I remember correctly from my contacts with the Dow Jones DGJI download group a few years ago,
then the file
filename.tar.gz
is a gnu compressed gz-format "mother of all files" file that holds a container file
filename.tar
which is a <simular to zip-format> based container file(virtual folder).
WinZip will not enable you to unzip the <tar container file> packed in the gz-file directly
nor the unzipped <tar container file> directly.
The gz file only holds some info on the contents tho, and is not ever an important file
nor was it or is it an important file format.
By deleting the extension
.gz
the container file
filename.tar
remains, and this file format can then <indirectly> be handled by WinZip as a plain zipped file.
I think what I did then was just renaming the file
filename.tar
to
filename.zip
and was then able to have WinZip(and the old DOS PKZip) to deal with the file and its further
contents, like is common when using WinZip.
Best is to stay the hell away from all this Unix stuff, since it's usage everywhere is not concistant
and cumbersome in usage.
The Dow Jones Co. tho, being an old solid firm, still uses the original intended capabilities and has
stuck to this 1960's file formatting (which on some "old" mainframes is still common).
I also was told then to use the gnu-unzip utility, but never got it to do what it was intended for, it
would blundly unzip all files into one folder, not maintaining the folder-structure. I couldn't ever be
bothered with finding out its illogic parameters structure, so was very pleased with WinZip when it
did what it was required to do:
have a bunch of ASCII files zipped into+scattered over the immense DGJI folder's-structure.
.ps
PostScript(ps) files are files written in machine language, (some still use the PRN extension) that
apart from the to be printed information also holds all the instructions for the printer
(layout, size, fonts, pageformat, pagebreaks etc.) and ps files require a Post-script printer driver
to be installed, files send to it and to be able to print ofcourse a postscript capable printer
(usualy a printer that is compatible to networks).
.pdf
PDF files are compressed RTF files creatable in a not-password protected RTF environment.
Since it is propriety(Adobe) it requires a seperate further useless progarm(editor).
Sort of like precreated visable postscript files, useless to the average user, and cumbersome to
work with for professionals. It is mainly used for publishing what many think is unalterable data,
which is not the case. But for libraries etc I suppose a sort of usable product.
Other than that, both file formats are not much used, and a pain in the a... to look at(ps) and to
work with(pdf) or to be used for other stuff(ps+pdf).

Hi Christian
Have forwarded the file to you. It opens in Ghost Script easly.
Anyone who wants it can ask Christian or myself for it. It's 171KB and too
big for the List.
For others: here is more general info from Ingber's site re different
utilities and file procedures. I'm sure that Ton has a collection of
information in his amazing library. Thanks Ton for your "Bands" post.
Best regards
Walter

Welcome to

If you have requested a UNIX-compressed file of type
FILE.Z
these files have been converted to gzip-compressed files of type
FILE.gz
so please retry your download using this modification.
To download gzip for any operating system (now standard on most
systems) go to
http://www.gzip.org
http://www.gnu.org/software/gzip/gzip.html
gzip (`gunzip` or `gzip -d`) also will expand UNIX-compressed and
zip-compressed files (not archives), i.e., FILE.gz, FILE.Z, and
FILE.zip files.
After decompressing, you will be left with a file like
file.ps
which is a PostScript file, or
file.tar
which is a tar file, or
file.shar
which is a shar file, or
file.txt
which is a simple ASCII text file.
A PostScript utility is required to view or print a file.ps that is
left. To download PostScript viewers or tools for any operating system
go to
http://www.aladdin.com
http://www.cs.wisc.edu/~ghost/index.html
The tar utility expands file.tar into a directory of files. ON UNIX
systems you can simply use `tar xf file.tar` or `tar -xf file.tar`. To
download the tar utility for any operating system go to
http://www.gnu.org/software/tar/tar.html
The shar utility expands file.shar into a directory of files. On UNIX
systems you can simply use `sh file.shar`. To download the shar
utility for any operating system go to
http://www.gnu.org/software/sharutils/sharutils.html
The zip utility expands file.zip into a file or a directory of files,
depending on how file.zip was prepared. To download the zip utility
for any operating system go to
http://www.faqs.org/faqs/compression-faq/part1/section-2.html
More information and direct links to these codes are given in

Thanks.
