# What are the Advanced options in New Transfer?

Open **Advanced options** in **New Transfer** to fine-tune a transfer:

- **Bandwidth limit** — a speed cap, so a big upload doesn't hog your connection. Blank means no limit.
- **Parallel transfers** — how many files move at the same time (1 to 32, default 8). Not shown for Download, which is one file.
- **Streams per file** — how many pieces of one large file are fetched at once (1 to 16, default 4).
- **First run for this pair** — only for Bidirectional sync, only on its very first run.

The defaults suit most people; change them when you have a reason to.
