Environment

This article applies to all Bowdoin College students, faculty, and staff who use Microsoft Teams as part of their Bowdoin Microsoft 365 account.

  • Applies to: Bowdoin-issued MacBook Pro, MacBook Air, Dell Laptop, and Dell Desktop.
  • Operating systems in scope: Windows 11, and macOS Sequoia (15.x) or Tahoe (26.x) and newer.
  • Applications in scope: a web browser, Microsoft Teams (desktop app and web app), and OneDrive (web and desktop sync client).
  • Permissions required: you must be a member of the Team, with permission to add files to the channel.
  • Where these files actually live: a channel's Shared tab is a folder in a SharePoint document library that belongs to the whole Team. Anything you put there is visible to every member of that channel. In some versions of Teams this tab is labeled Files. They are the same place.
  • Not in scope: setting up OneDrive sync for the first time, choosing between a shortcut and sync, sharing files with people outside Bowdoin, moving files out of Teams, and managing SharePoint site permissions. See the Related Articles section.

Resolution

Start here: pick the method that fits what you are moving

Choosing a method for moving files into a Teams channel
What you are moving Use this method Why this one
Files or folders already in OneDrive, Teams, or SharePoint Move to, in a web browser It is the only method that keeps a file's version history, and nothing has to be uploaded again.
A handful of files from your computer or from Microwave Drag them into the browser Nothing to set up, and you can see immediately whether every file arrived.
A larger set of files or folders from your computer or from Microwave File Explorer or Finder Handles more files than a browser window comfortably will.
Your department's whole folder on Microwave (J:) Contact the Service Desk The migration tools bring the folder structure and permissions across. A copy made by hand does not.

What decides whether version history comes with the file

Teams and SharePoint keep a version history for every file, so you never need copies named "v2" or "FINAL". Whether an existing history survives a move depends entirely on which method you use:

  • Move to, in a web browser, carries the version history to the new location. This is the only method that does.
  • Copy to brings only the most recent version.
  • File Explorer and Finder do not carry version history. The file arrives as a brand-new item, recorded as created by you on the day you copied it.

Note: Whether the channel appears on your computer as a shortcut or as a sync makes no difference to version history. Both are the same OneDrive connection underneath. Version history is decided by the method you use, not by how the folder got onto your computer.

Files coming from Microwave or from your own hard drive have no version history to begin with. Their history starts the day they land in Teams.

Do I need to sync the channel first?

No. You do not need to sync a channel in order to move files into it.

  • The two browser methods below need no connection to your computer at all.
  • If the channel already appears in File Explorer or Finder — as a shortcut or as a sync — use it as it is.
  • If it does not appear and you want it to, add a shortcut. A shortcut follows you to every computer you sign in to, and removing it later cannot harm anyone's files. See Add a Shortcut to a Teams Channel or Shared Folder in OneDrive in the Related Articles section.

Warning: Do not switch from a shortcut to a sync just to move files. OneDrive does not allow a shortcut and a sync on the same library at the same time, so switching means removing the shortcut, syncing, copying, stopping the sync, deleting the leftover local folder, and adding the shortcut back. There is no upload advantage that makes that worth doing.

Sync is still the right choice for its own reasons — needing only part of a large library, or using a program that requires a fixed folder path. See Choose How Teams and Shared Files Appear on Your Computer in the Related Articles section.

Move files already in OneDrive, Teams, or SharePoint

Use this whenever the files are already somewhere in Microsoft 365. It keeps the version history, it does not depend on anything being connected to your computer, and it cannot leave you with a half-finished upload.

  1. Go to https://office365.bowdoin.edu and sign in with your Bowdoin account, then open OneDrive.
  2. Browse to the file or folder you want to move and select the circle beside its name to check the box.
  3. Select Move to in the toolbar at the top of the page. If you do not see it, select the ... menu.
  4. In the Move items panel, choose the Team you want under Quick access. If the Team is not listed, select More places... and browse to it.
  5. Open the channel folder you want. Channel folders are named after the channel, such as General.
  6. Select Move here.

To move files that are already in a different Team or SharePoint site, start from that channel's Shared tab, select Open in SharePoint, and then follow steps 2 through 6.

Note: If the Team you want does not appear even under More places..., you are probably not a member of it yet. Ask a Team owner to add you, then try again.

Use Copy to instead only if you need the original to stay where it is. A copy does not bring the version history with it.

Limits on a single move

One Move to operation handles up to 30,000 files and 100 GB. On the OneDrive website you can copy up to 2,500 files at a time. Break a larger job into several moves, working folder by folder.

Move a handful of files from your computer using a browser

This is the quickest route for a small number of files, and it needs nothing set up beforehand.

  1. In Microsoft Teams, open the channel and select the Shared tab. In some versions this tab is called Files.
  2. Open the folder you want the files to land in.
  3. Drag the files from your desktop, from File Explorer, or from Finder onto the file list in the browser window.
  4. Wait for each upload to finish and confirm the files now appear in the list.
  5. Only then delete the originals.

Move files from your computer using File Explorer or Finder

Use this for a larger set of files or folders. Work through the checks below first — they prevent the two failures that account for nearly every incomplete move.

Before you start

  • Check the finished path length. The whole address of a file once it is in Teams — site, library, channel name, every folder, and the file name — cannot exceed 400 characters. A Teams channel adds a long prefix before your folders even begin, so deeply nested folders that were fine on Microwave often break this. Shorten folder and file names, and flatten to roughly three folder levels.
  • Check for characters that are not allowed. File and folder names cannot contain " * : < > ? / \ or |. They cannot begin or end with a space, and cannot end with a period. Items with these names are quietly left behind.
  • Delete what you do not need first. Start with the oldest and largest items. This is the single fastest way to shorten the whole job.
  • Close the files. On your computer and on anyone else's.
  • Confirm the channel appears on your computer. Look for it in File Explorer or Finder. If it is not there, add a shortcut to it.

Important: Copy the files first, confirm they arrived, and only then delete the originals. Never cut and paste. A dropped connection, a computer going to sleep, or a single unacceptable file name can interrupt a cut-and-paste and leave you without a complete set in either location.

Windows

  1. Select the File Explorer icon in the taskbar.
  2. In the left navigation pane, open the Teams channel folder you are moving files into, and leave that window open.
  3. Open a second File Explorer window by pressing Windows + E, then browse to the files you are moving.
  4. Select the files or folders, then press Ctrl + C to copy them.
  5. Switch to the Teams channel window and press Ctrl + V to paste.
  6. Wait for the OneDrive cloud icon in the taskbar to show a green checkmark. Keep the computer on, awake, and online. A large batch can take hours.
  7. Open the channel in Teams and confirm the files are there, that the count matches, and that several of them open correctly.
  8. Only then delete the originals.

macOS

  1. Open Finder from the Dock.
  2. In the Finder sidebar, open the Teams channel folder you are moving files into, and leave that window open.
  3. Open a second Finder window by pressing Command + N, then browse to the files you are moving.
  4. Select the files or folders, then press Command + C to copy them.
  5. Switch to the Teams channel window and press Command + V to paste.
  6. Wait for the OneDrive icon in the menu bar to show that syncing has finished. Keep the computer on, awake, and online. A large batch can take hours.
  7. Open the channel in Teams and confirm the files are there, that the count matches, and that several of them open correctly.
  8. Only then delete the originals.

Note: If your files are in a Desktop or Documents folder that OneDrive backs up, and drag and drop is not working, see Cannot Drag and Drop to OneDrive Redirected Folders in macOS Tahoe Finder in the Related Articles section. Copy and paste is unaffected.

Move your department's whole folder off Microwave

Do not migrate a department drive by hand. The Service Desk uses migration tools that bring the folder structure and file permissions across, work through invalid file names, and can run in the background and then cut over — none of which a copy made in File Explorer can do.

  1. Submit the Migration Assistance Request in the Service Catalog, or call the Service Desk.
  2. Review and clean up your folders before the migration. This is the part that most affects how well it goes. See Manage and Clean Up Department Files Before the Teams Migration and Transition Department Files to Microsoft Teams in the Related Articles section.

Confirm the move succeeded

Before you delete anything, check all four:

  • The number of files in the channel matches the number you moved.
  • OneDrive is not reporting any errors or skipped files. Look for a warning badge on the OneDrive icon and open it to see what it is reporting. Files with unacceptable names are left behind without an obvious warning.
  • Several files open correctly from Teams, including the largest one.
  • The colleagues who need these files can reach them in the channel.

Warning: Once you delete the originals, the copies in Teams are your only copy.

Troubleshoot

Some files did not arrive

Almost always an unacceptable character in a name, or a finished path over 400 characters. Check the OneDrive icon for a warning badge and open it to see which items were skipped. See Troubleshoot Microsoft OneDrive Sync Errors in the Related Articles section.

The upload looks stuck

Confirm you are online and the computer has not gone to sleep. A genuinely large batch takes hours, and the count can sit still for a long stretch while a big file uploads.

Move to is missing or greyed out

You may not have permission to add files to that channel, or the destination may be a private or shared channel you are not a member of. Ask a Team owner.

I cannot find the file after moving it

Check the channel's Shared tab in Teams rather than File Explorer, since a shortcut or sync can take a few minutes to catch up. If the file was in a chat rather than a channel, it is in your OneDrive, not in the Team.

The files went into the wrong folder

Use Move to in a web browser to relocate them within Teams. That keeps the version history intact.

I deleted something by accident

Check the recycle bin for the channel's SharePoint site. Deleted items can be recovered for 93 days. See How to Recover Documents in OneDrive, Teams, or SharePoint in the Related Articles section.
