When you upload a file larger than 100 MB while signed in — or through someone's File request link — FileMv automatically switches to a resumable, chunked upload. You do not have to do anything — the switch is invisible.
What resumable means in practice
The file is sent in small chunks, and the upload tracks exactly how much has been accepted. If your connection drops for a moment — a Wi-Fi blip, a network switch — the upload retries automatically and continues from where it left off, instead of starting over. You only see an error if the connection stays down through several retries.
What does NOT survive
The resume works within the open page. Keep the browser tab open until the upload finishes — closing the tab or the browser abandons the upload, and it has to be started again. Background uploads that survive a closed tab are not supported yet.
Smaller files and anonymous uploads
- Files of 100 MB or less upload in one piece — simpler and just as fast at that size.
- Anonymous uploads from the home page (no account) are capped at 100 MB, so they always use the simple path.
- A File request is the exception: people sending you files through your link get the resumable upload for every file over 100 MB, no account needed — the limits are listed in the File request article.
Tips for very large files
- A wired or stable connection matters more than a fast one — resumable uploads tolerate slowness well, but a tab put to sleep by the OS can stall the transfer.
- Watch the progress indicator; when it completes, the file appears in your Drive and is safe.
