File Chunk Joiner

File Chunk Joiner

Select or drop 2–500 chunks of the same file, set the output filename and click Merge files. Check the order and total size in the result, then click Download results. An empty filename uses joined-file.bin. Copy all copies the status text, not file bytes. There is no manual reorder control.

The whole filename is sorted with numeric-aware comparison: backup.part1 (AB), backup.part2 (CD), backup.part10 (EF) produces ABCDEF. No part counter is extracted. Check that filename order matches the original byte order. Output cannot exceed 128 MiB (134217728 bytes). It is raw concatenation, not PDF/image/ZIP merging, checksum validation or missing-part recovery; correct complete chunks are your responsibility.
