control izarc or winzip or winuha with labview

[madness]

Hi.

I have a lot of data with my acquisition program.
The idea is to compress it to file it.
How can I make an automatic program with labview to compress datas with winzip or izarc or winuha or anything else???
It's very important for me because my data can be more than 4 Go then compressed less than 300 Mo !
Can somebody help me on this point???

Thanks in advance.

Go here first you have to download the installer then you can download all packages.

read the instructions on the website to use it. You will have to change the pallette views in labview but it will be gratly rewarding when you do. I personally use it everyday for something.

Thank you for your help.

As another option, you can use zlib (a very commonly used freeware library) directly from LabVIEW. Its compression algorithm is very similar to WinZIP, so you should get similar results. Search for LabVIEW Windows Routines for Data Compression at the main ni.com prompt or try the following link

As the original developer of the OpenG lvzip library I just want to say
that it does make use of the zlib library internally. What I did was
merging the "zlib" library by Jean-loup Gailly and Mark Adler with the
"zip/unzip" code from Gilles Vollant and changing the export type of the
functions so that the same VIs could be used to call either a unix
shared library of that code or a Windows DLL version.

The next version currently under testing will support adding new files
to an existing archive, deleting files from an archive as well as
extracting password protected files.
