How to recover an interrupted large upload

Use TransferSize’s multipart progress and retries to continue after a temporary connection problem instead of immediately starting the whole file again.

Use this checklist here; the full reasoning stays below.

Guide01

Why progress may pause

The browser may be waiting for connectivity, retry backoff, a storage response, or final verification. Speed and ETA are estimates, especially after a network change.

Guide02

When a restart is appropriate

If the session has expired, the browser was closed, or the interface explicitly reports an unrecoverable state, begin a new upload and discard the old incomplete attempt from your workflow.

Guide03

Prevent repeat interruptions

Disable device sleep, avoid switching between networks, leave enough disk and memory headroom, and upload from the local source rather than an unstable mounted drive.

Edge cases

Before the handoff

Can I resume after closing the browser?

Do not depend on that. Keep the tab open and use the active session’s recovery behavior.

Does retry send the entire file again?

Failed multipart sections can be retried independently; a complete restart is not the normal response to one failed part.

Put the guide to work

Open the sender and follow the same sequence.
