I found this DLL library on extracting contents from RAR files. I didn't see anything about packing with this but this is a start. I am going to mess with it and see if it works well. Just thought I would share my find. I know bdi was looking for something to work with RAR files a while back.

This includes examples in C,C#,Delphi,VB.net,VB6

Enjoy!

Sweet. This makes me feel more like I might actually find a way to RAR them sometime. As you can tell, I still haven't gotten to that project.

Hmm.. what advantages does RAR have over 7Zip (If any)? The algorithm used makes for a very high compression rate, higher than RAR IIRC.

Well RAR is getting more popular for one. 7Zip I read about but I guess I'm a big RAR fan myself. Smile

7Zip would be nice for personal use but if you try sending someone a 7zip file you will definetely have to show them where to get an unpacker for it.

But never know 7Zip may get up in pop because it is open source! Smile

Heh, possibly.
Many installers use it (I know inno setup can use it for one). If people don't need to interface with it then it's nice to use internally.

Bear in mind that a few months ago people didn't know what the hell a .rar file was so you had to do the same.

True I have had to tell people what they need to open RAR files. If I know I am sending a compressed file to multiple people I will then convert it to ZIP so I don't have explain.. Laughing

BTW, I have been using WinRAR for more than a few months though Wink

I just noticed that Thunderbird (the email client from Mozilla that goes with Firefox) uses 7Zip as its installer compression.

RAR allows for far larger files than ZIP files. RAR also allows you to span files. I don't know much about 7Zip, so I can't compare it. I have used RAR files for years though.
