Why this helps
A large file may take hours. Sending it in parts means one short network problem does not have to erase all confirmed progress.
What TransferSize keeps
The open upload session records finished parts and retries the one that failed.
- Progress, speed, and time left
- Retry for failed parts
- A final size check
Keep the tab open
Recovery works inside the active upload session. If you close the browser or let the session expire, you may need to start again.
Questions people ask
Can one failed part damage the file?
TransferSize checks each part and the final byte count before it creates the link.
Does the browser hold the whole file in memory?
No. It reads and sends smaller parts.
Can I close the browser and come back later?
Do not rely on that. Keep the page open until Transfer ready appears.
Send a file without entering a card.
