Changing a drive's Drive Letter
I want to change my E drive's drive letter to D. And I have about a hundred games on this drive.

Is there any way to do this without re-assigning each game to the new path one by one?

Steam, settings, downloads, steam library folder, add the d:\steam and remove the e:\steam..
Close steam before you change the drive letter though..

That wont make the e drive d. Just would remove the folder from e.

Will Steam automatically remap all the games to the new drive letter?
You need the appmanifest files and the games folders in the right place to let steam see them.

Create the new library folder with steam on d, and install one game. To see where to insert the things there.
Have steam off while moving. Do not keep the games and appmanifest files in double places.

Try this

1) Shut Steam down
2) Re-assign drive letter
3) Navigate to your steamapps folder and open libraryfolders.vdf in notepad or some text editor
4) Change whichever library you have on E: to D:
5) Save and start Steam up, check to see if your games are still installed.

Thank you for your reply. That sounds like it might work... tbh though I posted this question hoping for a definitive reply that takes out the guesswork, cause I can't afford something going wrong and having to re-download 2TB of game files. I'll try Steam support with this question to see if they have an answer.

But thank you again for your reply.

Thanks but I'm not moving or copying anything. I'm just changing the drive letter of a drive.

What exactly do you expect to go wrong? You're changing the drive letter in your OS, and telling Steam to look at it.

Hi all, so I contacted Steam Support and it worked out. All you have to do is change your drive letter, then go to Steam>Settings>Downloads>Library Folders, and select the new location of your Steam library on that drive. Steam will automatically replace the old drive letter location with the new one, and it understands that your games are all in the new location. I'm really glad at how simple they've made it.

It's now 2024, and I'm not seeing "Library Folders" on the Downloads settings page. Like the OP, I want to change my drive letter (for me it's going from D to G) without losing access to all the games on this dedicated Steam drive. Any advice for this new and "improved" version of Steam we're all using today?

You can move games from one drive/partition to another.

If you want to change the name of the drive, you need to add that drive to the library drives.

It's the second option I want to do (same drive, just changing letters for convenience). What I need to know is HOW to update the library drive - the directions provided in my original quote don't seem to apply the the new Steam UI that was updated last year.
I think its, steam, settings, storage
