Join Split Files

Rejoin numbered file parts locally and verify every part using SHA-256 checksums.

How to use

1. Select the .lhtparts.json manifest and all corresponding numbered .part files.
2. The browser verifies part filenames, sizes, order and SHA-256 checksums before creating the original file.

About these formats

Validated joining restores the exact original bytes. It does not decode media, recompress archives or alter file contents.

Browser limitations

Only archives created with the LHTSOFT Files split manifest format v1 are accepted. Missing, duplicated, reordered or corrupted parts are rejected.

Frequently asked questions

Is a manifest required?

Yes. The manifest specifies ordering and per-part integrity checks.

What happens if a part is damaged?

Joining stops with an integrity error; no partial file is offered.
