## How to split a file into parts

1. Drop the file to split, and pick the part size.
2. Download the parts and the manifest, or the ZIP of all of them.
3. To join, drop all the parts together, in any order.

## Questions

### Is the joined file exactly the same?

Yes, when every part is there and matches. Joining puts the bytes back in order, and the manifest lets the tool check the SHA-256 of each part and of the whole file.

### Why is 2 GB one of the sizes?

Many drives use the FAT32 file system, which stores files up to 4 GB. Parts of 2 GB stay under that limit.

### Do I need the manifest to join?

No. Without it the parts are joined in number order and checked for gaps only, so a damaged part cannot be detected.

### Are my files uploaded?

No. The parts are cut from the file in this tab, and nothing leaves your device.
