Many FS (file systems) do not allow to deal with big files. For example FAT32 (the mostly used FS on USB sticks) is limited to 4GB. We have unfortunately a lots of ZIM files which are bigger than that.

The way the zimlib deals with that limitation is to allow to split ZIM files in smaller chunks like the UNIX tool does. But, this is not documented in the ZIM Specs., so another implementation might choose an other approach.

To avoid incompatibility between ZIM readers and ZIM files, we should document that too in the ZIM file format specification.
