Compressing and spanning files on upload

[Guest]

Hi,

I have a project which requires having users upload files to be burnt to
compact disk. The requirement is to zip (compress) and/or span files to
compact disk size on upload. I cannot use winzip all the time as there is a
4GB limit, which will be reached at times.

I enquired about using the develper version of PKZIp to overcome the winzip
4GB limit. However the cost of this software is an outrageous $3500 us + $300
per cpu on the web server.

Does anyone know of a viable solution which does not cost that much. Is
there support for zipping and spanning in .net? If so, are there any
limitations?

I would really appreciate any assistance.

thanks,
Sher

For all versions of .NET, you can use SharpZipLib

For .NET 2.0, check out System.IO.Compression.

Thanks Joshua. One question. I did not see any reference to spanning files in
the articles below. Did I miss something?
