Are the parts a true spanned archive?

No. Spanned ZIPs (.z01, .z02, ...) require all parts to reconstruct the original. Our split parts are independent ZIPs — each one opens on its own without the others.

What if a single file is bigger than the max part size?

That file is placed alone in its own part, which exceeds the limit. The tool will not slice individual files because the resulting fragments would not be openable.

How do I reassemble the parts?

You do not need to. Each part contains a complete subset of files. Open each part, extract, and the union is the original.

Does compression change after splitting?

No — files keep their original compression. Splitting only changes how files are grouped across multiple ZIPs.
