Hi all,

is there a way to create splitted Zip files with the Chilkat Zip Component? For example: 3 files, each with 100 MB (Filename.001.zip, Filename.002.zip, Filename.003.zip) and a file with 29 MB (Filename.004.zip), rather than a file with 329 MB (filename.zip)

Thanks for the help

Unfortunately, the ability to create multi-volume (split) zips is not a feature in the Chilkat Zip component. It's not in the future plans for a number of reasons:

1) The Chilkat Zip component will automatically use the ZIP64 extensions if a .zip grows beyond limits such that it's needed.
2) Over time, networks speeds improve, disk capacities increase, and all data transfer protocols (FTP, SFTP, HTTP, etc.) have resume functionality, so the need for splitting zips continues to decrease (in our opinion)
3) (this is the biggest reason) It's a feature that would require a significant amount of work, and other tasks always seem to take priority. For example, right now Chilkat is working on making the .NET API work with Mono such that C# (and VB.NET?) could be used w/ Chilkat cross-platform on Windows, Linux, Mac OS X, IOS, Android, etc..

thanks for the reply. I agree with point 2 in part. However, there are plenty of systems which have a maximum limit, such as Microsoft Exchange, with a maximum attachment size from 20 to 25 MB per email.

What currently constitutes a problem for me. Since I unfortunately can not create a multi-volume Zips, I have an alternative to work with the compressed file size and append single files into zip.

Thanks for the help. :)
