The 24-hour keep-alive is a simple rule that keeps your links useful for as long as people actually need them. Every time someone downloads your file, the link's life is extended by another 24 hours. Links that people keep using stay available, and links that nobody touches expire right on schedule and the files are permanently deleted.
How the keep-alive works
When you create a link, you pick an expiry: 1 hour, 12 hours, 24 hours (the default), 3 days, or 7 days. That sets the starting clock. From there, each download resets the countdown so the link stays alive for at least 24 more hours.
Think of it like a light switch on a motion sensor. As long as there is activity, the light stays on. When the room goes quiet, the light turns off on its own.
- A download happens: the clock is bumped to 24 hours from that moment.
- No downloads happen: the link expires at its scheduled time.
- The link expires: the file is permanently deleted.
An example timeline
Say you create a link at 9:00 AM Monday with the default 24-hour expiry. Here is how the keep-alive plays out:
| Time | Event | New expiry |
|---|---|---|
| Mon 9:00 AM | You create the link | Tue 9:00 AM |
| Mon 6:00 PM | A teammate downloads it | Tue 6:00 PM |
| Tue 10:00 AM | Another person downloads it | Wed 10:00 AM |
| Wed 10:00 AM | No more downloads | Link expires, file deleted |
The link kept renewing while people used it, then quietly expired once the downloads stopped. You did not have to touch a thing.
Good to know: Each download extends the link by 24 hours from that moment, no matter which starting expiry you picked. A busy 1-hour link can outlive a quiet 7-day one.
Does the keep-alive last forever?
Only while people keep downloading. Once 24 hours pass with no activity, the link expires and the file is gone for good. There is no backup or trash folder, so this is permanent. If you want a strict cutoff no matter what, see the options in can I delete or cancel a link after sharing?.
Why the keep-alive is handy
This feature solves a common headache: a link that dies right before someone needs it. Here is where it helps most:
- Busy teams. If several people are grabbing the same file over a couple of days, the link stays live without you re-sharing it.
- Different time zones. A colleague across the world can download hours later, and their download keeps the link fresh for the next person.
- Popular files. A file that many people want stays reachable as long as the interest lasts.
- Hands-off cleanup. The moment interest fades, the file deletes itself. You never have to remember to remove it.
Because unused links still expire on time, your private files do not linger. This is part of why expiring links are safer than links that stay up forever.
Keep-alive with other options
The keep-alive works alongside your other choices, with one important exception:
If you want a link that renews with use, keep the burn option off. If you want it gone after one grab, turn it on.
