Data Transfers · Speed and advanced options
What are the Advanced options in New Transfer?
Short answer: Advanced options holds Bandwidth limit (a speed cap), Parallel transfers (files at once, 1–32), Streams per file (pieces of one big file, 1–16) and, for a new two-way sync, First run for this pair.
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.
