compression application

[Neo]

I am developing compression application in C++ (vs2k5) using zlib library
for compressing files/folders. I understand how to compress a single file,
but is there any way to compress a folder containing subfolder and files? I
mean is there some single function that does this or will I have to write my
own.



Regards,

ZLIB doesn't include code to compress multiple files into a single file (a
la ZIP). You can invent your own format, or you might want to take a look
at "info-zip" http://www.info-zip.org/ for an open-source version of ZIP
(and the "parent" project of ZLIB).

No, you don't have to write your own, this is a common need.

If you are writing managed code, here are two options:

1) SharpZipLib, an open-source library (http://sharpziplib.com)

2) Xceed Zip for .NET, a professional library (http://xceedzip.com)

If you are writing unmanaged code:

3) Xceed Zip ActiveX/COM (http://xceedsoft.com/products/zipCompL)
