You swap the file behind a link without resending it by replacing the document inside the room, not by creating a new link and asking the recipient to use it instead. Because the link points at the document rather than a fixed file, the same URL opens whichever version is current.
Steps to swap the file
- Open the [room](/glossary/virtual-data-room/) holding the document that needs correcting.
- Right-click the document (or open it and use Replace file next to Share) and choose Replace file, rather than adding a brand new document, so the link and its history stay attached.
- Choose the corrected file. It must be the same type as the original: a PDF replaces a PDF, a Word file replaces a Word file. Add a short note under "What changed", then choose Publish now. Save as draft keeps it off every link until you publish.
- Open the link yourself to confirm it shows the new file. A recipient who already has the document open keeps reading the pages already loaded; the new version appears the next time they open the link.
- Decide whether to tell people. The note you type under "What changed" is shown to recipients as the reason the document changed, so write nothing there you would not want them to read. If they should not see the document at all any more, revoking the link may be the safer move.
- Check the document's Activity tab to see whether anyone opened the file before you replaced it, so you know if the mistake was actually seen.
Edge cases and what to check
If the recipient already downloaded the old version before you swapped the file, that copy is unaffected by the change. Swapping the file behind the link only affects what happens the next time someone opens it through that URL, not copies that already left the room.
One real catch: a document that has been sent for signature cannot be replaced, so the signed copy can never drift from what was signed. Upload the corrected file as a new document instead. A link you created for one exact version also keeps showing that version.
Replacing works on every plan, including Free. Free and Plus upload PDFs, so you replace a PDF with a PDF; Word, Excel and PowerPoint uploads, and replacing them, are on Pro and above. Text documents are edited in the editor rather than replaced.
After replacing, check two things. First, that the new file is actually the corrected one and not an older draft pulled from the wrong folder. Second, that the document's Version history shows the change clearly, with your note, so anyone looking back later understands what happened and when. The link keeps all its settings (access, expiry, passcode, downloads) because you changed the file, not the link.
If your current tool cannot do this
Many everyday sharing methods have no concept of a link pointing at a mutable document. Once you have sent an attachment or generated a static download link, correcting a mistake means sending an entirely new one and hoping the recipient uses it instead of the old copy. Judge a tool against these questions.
- Does the same link serve whatever version currently sits behind it, or is each link permanently tied to one fixed file?
- Can you tell whether the recipient opened the old version before you noticed the mistake?
- Does swapping the file keep the settings, like an access check or an expiry date, attached to the original link?
A tool where the link points at a live document rather than a frozen file clears this bar. 99 Data Rooms works this way on every plan, and our guide to version control for documents you have already sent covers the broader problem this solves beyond just swapping a file. If you are still comparing this against a generic cloud drive, data room vs shared drive sets out why the two behave differently here, and the underlying tracking is the same one covered in visits vs verified readers.
Swap the file vs send a new link
| Swap the file | Send a new link | |
|---|---|---|
| Recipient action required | None, same link works | Must open a different URL |
| Old link still works elsewhere | Yes, automatically updated (unless a link was created for one exact version) | No, it now points at outdated content |
| Risk of confusion | Low | Higher, two links exist for the same document |
| Preserves gating and settings | Yes, the link keeps its settings | Only if manually rebuilt |
Sending a new link every time you correct a mistake creates duplicate URLs floating around, some pointing at outdated content. Swapping the file avoids that entirely.
Frequently asked questions
Does swapping the file change the link's URL? No. The URL stays exactly the same. What changes is which version of the document that URL serves, which is the whole point of pointing a link at a document rather than a fixed file.
Will the recipient be notified automatically when I swap the file? Only if you ask. The "What changed" note is shown to recipients as the reason the document changed. If a link is set to "Show earlier versions and email them", people who gave their email and had opened the document get one email, and the "Tell people who opened an earlier version" box in the replace dialog controls whether it goes out. Saving a draft emails nobody, and anyone who reopens the link sees an Updated notice.
Can I see if someone read the old version before I swapped it? Yes. The document's Activity tab lists each visit with who opened it, when, for how long and how far through they got, on every plan, so check it before you replace the file. The time on each page is from Plus, and only the owner and admin members see it.
Do I need a paid plan to swap the file behind a link? No. Replacing a file is on every plan, including Free, for PDF documents. Word, Excel and PowerPoint are on Pro and above, so on Free and Plus you replace a PDF with a PDF.
What happens to a downloaded copy of the old version? Nothing. Replacing the file has no effect on a copy the recipient already saved to their own device. For future visitors, set Downloads to Off on the link (on every plan), or choose PDF copy rather than Original file.
Fix it without a second link
Correct your next mistake by replacing the file inside the room rather than sending a second URL, and check the document's Activity tab to see whether the old version was actually opened first. Start free and keep one link, one document, always current.
Two links for the same document is a small mess that grows over time, as recipients forward whichever one they happened to receive first. Keeping a single URL that always resolves to the latest version removes that confusion, without you having to track who has which link. If a link should live for a fixed window rather than indefinitely, see how long a document share link should stay live.
