Hi,
I already implemented yesterday the feature, that zimfile handles multiple parts in a file. It works fine here. Currently I use the naming convention from split but this is easy to change.
That's good news. While for users of 2GB/4GB limited devices it would be easier if all zim files were limited to 2GB with internal references to the other files, I agree that this would impact user experience on devices without this limitation. Kind of dilemma, but your solution is fine for me, in particular considering that in the future most devices will support larger files. (e.g. SDXC cards won't have this limitation). However, we should strongly consider to define a standard naming scheme for parts. *part.zimN is fine for me. This ensures that is possible to put pre-split files for download, without being required to give instructions how to rename them for the different applications. Also if the end-user has to be split the files, it is easier if there is a standard way to do it. Note, that this may actually be only a definition, with is not implemented in the zimlib but by the applications. However, I'd prefer if it is supported in the zimlib (for example as an separate open method).
Furthermore, a check (e.g. on opening) whether the file set is complete would be helpful. I am not sure whether there is a feasible solution for this. However, if you have any idea how to do this, I think it would be a very useful feature.
Best regards, Christian

I thing naming convention is not the best solution, I do not like the idea to have a zimlib depending on filenames. For thousands reasons the ZIM file names may change.
What about: *zim::file constructor accepting also directory filename and if directory loads all files inside and merge them (easy for the app. dev. but a little bit tricky) *zim::file constructor accepting a list of ZIM file chunks (less handful for the app. dev. but clean)
Additional question: ist NTFS not widely supported?

Hi,
this directory solution has the problem, that there is no standard way to access directories. A list of files is easier to handle. Zimlib may even accept a list of files in one string separated by colon like in the PATH variable. Then you could open a zimfile using e.g. "myfile.zim.part1:myfile.zim.part2:myfile.zim.part3". Zimlib may parse the list and use these file names. The advantage is, that the files do not need to be in the same directory. If the filename contains a colon itself (I know one operating system, which do not use mount points but partition names separated by colon like C:\somefile.zim), it may be escaped with a backslash, so passing the file name must be passed as "C:\somefile.zim".

And NTFS is widely supported but only on one operating system and not on every device. If you buy a usb stick, it is formatted with fat, which has this 2G or 4G (I don't really know) limitation.
