Tips for Joining Files
- Order matters: Upload chunks in the exact sequence they were split.
- Batch queue helps: Add several chunk sets to the queue when you need to rebuild multiple files in one session.
- Check total size: The total size should match the original file before splitting.
- Verify the result: After joining, open the file or compare checksums to confirm integrity.
