ZIP, UNZIP v11 Beta

[Joe Caverly]

Hi,
Just used the ZIP command to create the mytext.zip file, using;

ZIP mytext.zip *.txt

One of the .txt files, jlc.txt, was a compound document file, consisting of the jlc.txt file, and the sol2.exe file.

When I did an;

UNZIP /v mytext.zip

it returned the following;

2009-09-02  06:55             30  14%  history.txt
2009-07-18  09:35             11 -18%  jlc.txt
2009-08-06  21:38            102  25%  jlc_powershell.txt
2009-08-02  08:42            458  44%  mailto.txt
2009-06-03  09:50             80  10%  nocopy.txt
2003-00-02  17:04          1,152  49%  readme.txt
2009-06-25  20:58            279  65%  recentdocs.txt
2009-07-18  08:07            102   2%  sb.txt
2004-04-10  13:50            840  50%  TuFix.txt

Note the -18% compression on the jlc.txt file.

When I extracted the jlc.txt file, using;

unzip mytext.zip jlc.txt

all I got back was the jlc.txt file. The sol2.exe file is no longer there.

Thus, am I correct that ZIP and UNZIP do not support compound document files?

Not yet. That's planned but it may not make it into the initial v11
release.

Could you email me (directly to rconn@jpsoft.com) your compound document so I can test it here?

Thanks.

Thanks.

For others who may not be familiar with this type of file, here's a .BTM that will create, and display, these types of files;

@setlocal
@echo off
::Create the NTFS File
::
echo Test File > jlc.txt
echo This is a test > jlc.txt:hidden.txt
type c:\windows\system32\sol.exe > jlc.txt:sol2.exe
::
:: Add some summary data
::
echo %@summary[jlc.txt,Title,This is a test file]
echo %@summary[jlc.txt,Author,Joe Caverly]
::
:: Take a look at the file
::
type jlc.txt
::
:: Take a look at the hidden.txt file
::
type jlc.txt:hidden.txt
::
:: Launch Solitaire
::
start /PGM jlc.txt:sol2.exe
::
:: Summary Title
::
echo %@summary[jlc.txt,Title]
::
:: Summary Author
::
echo %@summary[jlc.txt,Author]
endlocal

The only program that I know of that will display a directory listing of a compound document is the V program by Charles Prineas. Alas, this is a GUI, not a CLI.

Maybe someday TC will be able to display this type of file via the DIR command.

I basically use the compound document format as a "poor mans" archive. While it does not offer any form of compression, it's rather easy to keep a group of related text files, or other documents, all grouped together.

TCC already can -- "dir /:".

But I haven't found any zip program that will handle it.

TCC will do it. Use DIR /: ...

The type of file you are showing is not a compound document. Compound
documents are a COM construct that was developed back in the days when
OLE2 came out and MS Office had a requirement to embed excel docs inside
of word docs, etc. Compound documents do not have a filesystem dependency
- i.e. they work just as well on FAT as they do on NTFS.

What you are showing is a feature of NTFS called streams. 4NT/TCC has has
support for streams for years. Use the /: switch on the DIR command.
