AllFileGo sends a large file in small pieces instead of loading the whole file into memory or uploading it first. AllFileGo does not set a byte limit, but your browser, free storage, network, and the 100-file selection limit still matter.

How large files move

Large files are sent in small pieces to limit memory use.

  1. 1ReadThe sender reads a small part of the file.
  2. 2SendThe sender limits how much data waits in memory.
  3. 3WriteThe receiver writes each part to temporary storage.
  4. 4CheckThe final size and fingerprint must match.
01

Prepare both devices

A large transfer happens live. Keep both devices online and awake until it finishes. Make sure the receiving device has enough free space. Choose a destination folder if the browser offers that option.

If the receiver uses the browser's Downloads folder, AllFileGo temporarily stores the incoming file inside the browser until verification finishes. The browser needs enough temporary storage as well as enough space in Downloads.

  • Keep both devices awake and the browser available
  • Use a locally stored source instead of a cloud-backed file provider
  • Choose a destination folder where the browser supports it
  • Leave extra free space for temporary browser storage when using Downloads
02

How AllFileGo limits memory use

The sender reads and sends only a controlled amount of data at a time. The receiver writes and checks each part as it arrives. This prevents the whole file from being held in memory at once.

The slowest part sets the overall speed. That may be the source storage, sender upload, Wi-Fi or internet route, receiver processing, or destination storage.

03

What pause and recovery can do

Pause stops new file data after the small amount already in transit reaches the receiver. If the network changes briefly, the transfer may continue from the last part the receiver confirmed.

Closing or reloading either page ends the transfer. AllFileGo does not create a permanent resume link or keep a file copy for later.

04

Incomplete files are not saved as complete

Incoming data stays in temporary private storage until the whole file arrives. AllFileGo saves the completed file only after its size and SHA-256 fingerprint match the sender's file.

If the transfer is stopped, storage runs out, or verification fails, AllFileGo removes the temporary data instead of showing a partial file as complete.

05

When cloud storage is a better fit

Use a stored transfer link or cloud drive when the receiver cannot be online now, when you need one file to remain available to several people, or when restrictive networks cannot establish a direct route.
