Compress files in vb.net?

[tgf-47]

I'm just wondering if it is possible to create an vb.net application to compress files, without using a 3rd party app.

If yes, can you please point me in the right direction, give me some tips, tutorials or sample code?

I will appreciate any help, thanks

Hi,

Compressing and Decompressing files as very complex.
Perhaps you can find some good information, here.

Hi sparrow1.

I tested that code before. It seems to make the file bigger, rather than to compress it.

A .docx file went from 147kb to 179kb after compression with application.

Thanks a lot for the link though

I use the #ZipLib library from ic#code ... http://sharpdevelop.net/OpenSource/SharpZipLib/ when I need to compress/decompress files.

I was trying to solve this issue today. I gave up on a pure-VB.net solution. Instead I just downloaded the command line version of 7zip and use

Process.start("7za a -tzip archive.zip Folder", , True)

to compress my folder(and wait for it to finish). If I had done that from the get-go I would have saved an hour or two.

Sure, I have to include the executable, but since I'm not distributing this application I really don't care.
