In order to implement this feature I chose to use the third-party JSZip library, which is a light wrapper around the zLib library. While the namespace does provide an interface for compressing individual files, there is no native support for creating a multi-file archive. This operation needed to occur without the user’s direct involvement as part of a larger data transmission process. The intent was to shrink the several large files as much as possible for eventual submission to a central server. If you have the original files, it may be easier to just rar them and work with that.I recently encountered a requirement to programmatically zip multiple files into an archive in a Windows 8 JavaScript/HTML app. One trick you can potentially use is to "rar" the original zip file, that way you can reassemble it on Windows. Transfer these to Windows, then unrar the first one (destination.rar), which will link to the others automatically.
On Ubuntu, install the rar package, then: rar a -v32M destination.rar files/to/compress You can also use rar which natively supports creating "split" archives which can then be decompressed by a GUI tool on Windows such as WinZip or WinRar.
One working approach is copy /b ZIPCHUNKS* > reassembled-zip.zip. Is there replacement for cat on Windows may help, but note that the Windows type command will not work as it adds the files names between them when processing more than one file. Since you want to do the reassembling on Windows, you need a substitute for cat. Traditionally you'd use cat to glue them back together: cat ZIPCHUNKS* > reassembled-zip.zip Change the 32M parameter to vary the chunk size. This will create a bunch of ZIPCHUNKS* files, in order, and all 32 MB or less in size. Something like this should work: split your-zip.zip -b 32M ZIPCHUNKS On Ubuntu you can use the split command to split your zip file.
