How to track a shared file: who opened it, for how long, and on what device
Track who opened your file
To see who opened a file you shared, send it as a tracked link instead of an attachment. Link in Seconds is a free tool that does this: upload the file, send the link, and every open shows up with the time, how long the person read, how far they got, their device and city, and whether they came back. Turn on the email gate if you need names, and view alerts if you want an email the moment it is opened.
An email attachment can't answer any of that. A tracked link can, without the creepy parts: no cookies, no stored IP addresses, no names unless the reader gives you one. Here is what you can find out, how each number is measured, how it compares with the other options, and the honest limits.
The short version
- Upload the file and get a link.
- Send the link instead of attaching the file.
- Open the link's analytics to see opens, time spent, how far people got, device and location.
The rest of this post is what those numbers mean, so you can trust them.
Is there a free tool that shows when someone opened my file?
Yes. Here is how the common options compare for the question “did they open it, and what did they read?”
| Option | Shows the file was opened | Time and pages read | Names | Price |
|---|---|---|---|---|
| Email read receipt or tracker | No, only the email | No | Only if they accept the receipt | Free |
| Google Drive or Dropbox link | Partly, mostly for signed-in viewers | No | Signed-in viewers only | Free |
| DocSend | Yes | Yes | With an email gate | Paid plans |
| Link in Seconds | Yes, every open | Yes, time per page and how far | With an email gate | Free |
What you can see about each open
| Question | What the report shows | How it is measured |
|---|---|---|
| Was it opened? | Views, and the time of every open | Each page load of the link, minus bots and link previews |
| By how many people? | Unique visitors | A one-way hash of the network address; the address itself is never stored |
| For how long? | Average and median time, plus time per visit | Seconds the tab was visible and in focus |
| How far did they get? | Pages reached, percent watched or percent scrolled | Reported by the viewer as they read |
| On what device? | Desktop, mobile or tablet, plus browser, OS and screen size | Read from the browser's user agent and window size |
| From where? | Country and city | A coarse location from the request, not a stored address |
| How did they arrive? | Direct, QR scan, album, embed or another website | The QR marker, the album page or the referrer |
| Did they come back? | Returning visitors, and visits per person | The same hashed network opening the link again |
| Did they keep a copy? | Downloads | Counted when the file is saved |
Time spent, measured properly
“Time on page” is where most tracking tools quietly lie. If someone opens your file, switches to another tab and comes back an hour later, a naive tracker reports an hour of reading. Here the clock only runs while the tab is visible and the window is in focus. It pauses when the tab is hidden or the device locks, and it stops when the visitor leaves.
You get the average, the median (which one very long visit can't drag up) and the share of quick bounces, opens that lasted under five seconds.
One visit at a time
The Recent views table lists the latest opens: when, the city and country, device and browser, where they came from, how long they stayed and how far they got, such as “6 of 15 pages”. Expand any row to see that single visit page by page.
The Visitors card groups visits from the same network, so “Visitor from Manchester, 2 visits, 15 of 15 pages” tells you someone came back and finished it. That is usually the person to follow up with first.
Want to know who, by name?
Analytics never shows names or email addresses on its own. If you need to know exactly who opened a file, turn on “Ask for the viewer's email” in Link settings. Readers type an email before the file shows, and you get a Viewers table you can export. Readers see the request up front, which is the honest way to do it. The full setup is in ask for an email before the file opens.
Get told the moment it is opened
Checking a dashboard is fine. Being told is better. Turn on “Email me when viewed” and you get an email when someone opens the link, at most once an hour per link so a busy link doesn't flood your inbox. The best time to reply to a proposal is right after it has been read.
The honest limits
- Shared networks blur people together. Two colleagues on the same office Wi-Fi can count as one unique visitor. One person who opens the link at home and then on mobile data can count as two.
- Messaging apps often hide the source. Many chat and email apps send no referrer, so those opens show as Direct.
- Scanners and previews exist. Email security scanners and chat link previews can open a link before a person does. Known bots are removed, and the brief opens a scanner leaves are flagged as atypical and kept out of every average. We wrote a whole post on why view counts look too high.
- Time needs JavaScript. A visitor with JavaScript off still counts as a view, but not time or progress.
Which files this works for
Any file you share as a link. PDFs get page-by-page reading (see which page readers stop on), videos and audio get watch-through, and images, web pages and text files get scroll depth. For PDFs specifically, our guide to knowing if someone opened your PDF compares the other methods too. Ready to try it? Send a tracked link.
Quick answers
Can I see the name of the person who opened my file?
Not by default. Analytics shows when, how long, how far, the device and a coarse location, but never a name. To know exactly who opened it, turn on Ask for the viewer's email in Link settings, and readers enter an email before the file shows.
Is file tracking free?
Yes, all of it, on every plan: views, unique visitors, the views-over-time chart, time spent, completion, devices, location, sources, per-visit details, the Visitors card, view alerts and CSV export.
Does the reader know the file is tracked?
The link opens like any web page. The tracker sets no cookies and stores no IP addresses, and what it collects is listed in the privacy policy. If you turn on the email gate, readers see that request before the file opens.
Can I export the tracking data?
Yes, on every plan. Export CSV downloads one row per open with time, location, device, source, time spent and progress, up to 10,000 rows. The same report is available as JSON from the analytics API and to AI assistants through the MCP server.
How do I know if a recruiter opened my resume?
Put your resume behind a link and send the link, or add it next to the attachment in your email and signature. Every open shows up with the time, how long they read and their city, and you can get an email the moment it is opened. An attachment on its own can never tell you.
Can I track who opened my sales deck without DocSend?
Yes. Link in Seconds shows opens, time per page, how far each reader got and return visits, asks for the viewer's email if you want names, and alerts you when the deck is opened, all on the free plan. DocSend is still the pick when a sales team needs a shared content library, NDA gates or e-signature.
Do trackable links actually help with client follow-up?
Yes, because they change what you follow up about. Zero opens means the email was missed, so resend it. An open with a short read means they skimmed, so offer a call. A return visit that reaches the last page is the best moment to reply. View alerts tell you that moment as it happens.
