Large file split and join

Move a file across a size limit, then put it back together safely.

File splitting is useful only if joining is predictable. Kondor recognizes common part naming, checks for missing pieces and changed inputs, hides incomplete output, and publishes the finished file only after success.

FAQ

Quick answers before you choose.

Which split format does Kondor use by default?

Kondor uses the common numbered convention when no existing files determine another recognized format.

Can Kondor join .001 files?

Yes. Kondor recognizes `.001`, `.part001`, `.chunk001`, and GNU-style alphabetic part sets.

What happens if a part is missing?

Kondor reports the gap instead of silently publishing an incomplete joined file.
