How Many Ways to Access Files in SharePoint Are There
Why There's Still Only One Version
You can reach a file stored in a SharePoint document library in a surprising number of ways — through a web browser, syncing to your computer, a shortcut in OneDrive, a tab in Microsoft Teams, an email in Outlook, directly from Word or Excel, or from your phone. Whichever of these you use, it's still the same file in the same place, in a single version. A copy is only created by one specific extra step — and that's the one worth being able to recognize.
Why it matters that it's still the same place
A SharePoint document library is a single central store. A web browser, a folder synced to your computer, a tab in Teams, or a mobile app are just different "doors" into the same library — not separate copies of the files. Because of this, when you edit a file through any of these methods, everyone else sees the change immediately too, no matter where they access it from.
Overview of access methods
| Access method | Where the file opens | Creates a separate copy? |
|---|---|---|
| Web browser (SharePoint or Teams) | Directly online, in the browser | No |
| Sync to a computer (OneDrive sync) | In File Explorer, even offline | No |
| Shortcut in OneDrive (Add shortcut to OneDrive) | A link in your OneDrive, opening the same library | No |
| Shared tab in a Teams channel | Within Teams — it's the same library as on the team's SharePoint site | No |
| Opening directly from Word / Excel / PowerPoint | In the app, via "Open" → site | No |
| Mobile app (SharePoint / OneDrive) | On a phone or tablet | No |
| Email in Outlook — send a link | Directly online, same library as in SharePoint | No |
| Email in Outlook — send a copy, or downloading the file | A separate file in the email or on disk | Yes |
Web browser, sync, and the OneDrive shortcut
Web browser
- Open the SharePoint site (or click a shared file's link) and navigate to the document library.
- The file opens directly in the browser (Word, Excel and PowerPoint also have web versions) — nothing is downloaded to disk.
Syncing to a computer
- In the document library, click "Sync" — the folder appears in File Explorer.
- The files inside aren't copies — it's a continuously updated mirror of the same library, available even without an internet connection.
Detailed steps and the differences between licenses can be found in the article Syncing SharePoint to OneDrive on Your Computer.
Shortcut to OneDrive (Add shortcut to OneDrive)
- In the document library, click "Add shortcut to OneDrive".
- A link that looks like a folder appears in your OneDrive — in reality it just points to the original library in SharePoint, without downloading all of its content.
The difference compared to syncing: a shortcut doesn't download files locally in advance, it just makes the same library accessible in one place within your OneDrive — useful when you need quick access but don't want the entire content available offline on your computer as well.
Microsoft Teams, Outlook, and the Office desktop apps
An Outlook attachment — a link instead of a file
- When you attach a file in Outlook that's already in OneDrive or SharePoint, Outlook asks "Send a link or send a copy".
- When choosing a link, you can also set the permission level — for example "Organization can edit", "Organization can view", "Specific people can edit", or "Specific people can view".
- Access to a sent link can be changed or fully revoked at any later point via "Manage access" — once a file has been sent as a copy, that's no longer possible.
The shared tab in a Teams channel
- Open the team's channel and click the "Files" tab.
- The "In library" section shows exactly the same document library that belongs to that team's SharePoint site.
A file uploaded through Teams therefore doesn't end up "in Teams" — physically, it's stored in SharePoint, the same as with any other access method.
Opening directly from Word, Excel, or PowerPoint
- In the app, choose "Open" → "Sites — [organization name]", or paste a direct link to the file.
- The document opens and saves directly to SharePoint — changes sync continuously, and several people can collaborate at once in real time.
Mobile app
- In the SharePoint or OneDrive app on your phone or tablet, sign in with the same work account.
- Navigate to the relevant site or library — the files are the same as on your computer, with no need to forward anything.
What actually creates a separate copy
While all of the methods above keep things "in one version", the following steps deliberately split it into two:
- Downloading the file (the "Download" button) — creates a separate copy on disk that no longer stays in sync with the original in SharePoint.
- Sending a copy in Outlook (instead of a link) — every recipient gets their own copy; if someone edits it, the change doesn't propagate anywhere else.
- "Save as" to a local drive — exactly the scenario addressed in the article Why Company Data Doesn't Belong on a Local Computer Drive.
So why is it better to choose a link rather than a file when sending email:
- One version, no divergence — everyone works with the same, continuously up-to-date file, not with their own disconnected copy.
- Access can be managed or revoked at any time — via "Manage access" you can later restrict or fully revoke anyone's access; a copy that's already been sent can't be taken back.
- No attachment size limits — a link takes up only a few bytes in an email regardless of the size of the file itself.
- The recipient always sees the latest state — including ongoing edits, if someone is still working on the file.
Common mistakes and recommendations
- Sharing as an attachment instead of a link — when sending a file to a colleague or partner, prefer a shared SharePoint link over attaching the file to an email.
- Unnecessary downloading "just in case" — if you only need to view or edit a file, there's no need to download it to disk first; it's faster and safer to open it directly online.
- Uncertainty about which version is the "right" one — if a downloaded copy keeps being edited locally afterward, it eventually becomes unclear which version is current; the solution is to always go back to the original file in SharePoint.
- Unnecessarily creating both a shortcut and a sync at the same time — one access method is enough for normal use; having several parallel paths to the same library tends to create confusion rather than simplify things.
