How to Move Large Files From C Drive to Another Drive in Windows 11

Find What's Actually Filling the Drive First

Before moving anything, open Settings, then System, then Storage, and let Windows 11 scan the C drive. It breaks usage down by category — apps, documents, temporary files, and so on — so you're not guessing which folder is actually the problem. On most PCs, the real space hogs are one of three things: a Steam or game library that quietly grew to 200GB+, a Downloads folder nobody ever empties, or a specific app (a video editor, a virtual machine, a design tool) that stores its working files on C by default.

Once you know the culprit, the right move depends on what it is. Personal files (Documents, Downloads, Pictures, Videos) move cleanly with File Explorer's built-in Location tab. Installed programs need a proper uninstall-and-reinstall-elsewhere, not a manual folder drag. Game libraries have their own built-in move tool inside Steam and most other launchers.

Move Personal Folders (Documents, Downloads, Pictures, Videos)

Windows 11 has a built-in way to relocate your user folders that keeps every shortcut, every "Save As" dialog, and every app that points to "Documents" working exactly as before — because you're not just copying files, you're telling Windows where that folder actually lives now.

1. Open File Explorer and right-click the folder.

   Right-click Documents, Downloads, Pictures, or Videos in the sidebar, then choose Properties.

2. Go to the Location tab.

   Click Move, then pick a folder on your other drive — for example D:\Documents. Windows creates the folder if it doesn't already exist.

3. Confirm the move.

   Windows asks if you want to move all existing files to the new location. Say yes, and it copies everything over, then removes the old copy once the transfer finishes successfully.

4. Repeat for each folder you want to move.

   Documents, Downloads, Pictures, Videos, and Music can each be redirected the same way, independently of each other.

Move an Installed Program to Another Drive

Programs are different from personal files — they're not just data, they're registered with Windows (registry entries, shortcuts, file associations), so dragging their install folder to another drive almost always breaks them. The reliable path is uninstalling and reinstalling with a different destination selected.

1. Check if the app supports a custom install path.

   Most modern installers ask where to install during setup — that's your chance to point it at D:\Programs instead of the default C:\Program Files.

2. Uninstall from Settings > Apps > Installed apps.

   Find the program, click the three-dot menu, and choose Uninstall. This removes it cleanly, including registry entries the manual-drag method leaves behind.

3. Reinstall and choose the other drive.

   Run the installer again and select your D drive (or whichever drive you're moving to) as the destination when prompted.

Move a Steam or Game Library Without Redownloading

Games are usually the single biggest space consumer on a gaming PC, and thankfully Steam (and most other major launchers) has a built-in move tool that transfers the installed files directly rather than making you redownload everything from scratch.

1. Add a new library folder on the target drive.

   In Steam, go to Settings > Storage, click the three-dot menu next to your drive list, and choose Add Drive to create a new library folder on D:.

2. Right-click the game in your library and choose Properties.

   Under the Installed Files tab, click Move Install Folder.

3. Select the new drive as the destination.

   Steam copies the existing game files over rather than redownloading them, so a 100GB game moves in minutes, not hours, depending on drive speed.

Other launchers — Epic Games, Battle.net, EA app — have similar built-in move options under each game's settings menu, following roughly the same pattern.

Change Where New Files Save By Default

Beyond moving what's already there, you can stop the problem from coming back by changing where Windows saves new content going forward. Under Settings > System > Storage > Advanced storage settings > Where new content is saved, you can set separate default drives for new apps, documents, music, photos, and videos.

This doesn't move anything that already exists — it only applies going forward — so pair it with Methods 1-3 above for a complete fix rather than relying on it alone.

What You Can (and Can't) Move

How Much Space This Actually Frees Up

The size of the win depends entirely on what was filling the drive in the first place. Moving a Documents folder full of spreadsheets might free a few gigabytes; moving a neglected Downloads folder full of old installers and video files can free tens of gigabytes; moving a full Steam library is often the difference between a drive that's 90% full and one with genuine breathing room. Check Settings > System > Storage before and after to see the real number for your machine rather than assuming.

Do I Need Third-Party Software to Do This?

No — every method above uses tools already built into Windows 11 or into Steam/other game launchers, and none of them cost anything or require installing extra software. Third-party disk-transfer tools exist and can be convenient for very large one-time migrations (like moving an entire user profile at once), but for the common case of freeing up space by relocating a few folders, the built-in Location tab and storage settings cover it completely.

Be cautious of paid "PC cleaner" tools that promise to do this automatically — several bundle unrelated software or make sweeping registry changes that are harder to undo than the manual methods above, for a task that doesn't actually need automation.

Moving the AppData Folder Needs a Different Trick

AppData (hidden by default, found at C:\Users\YourName\AppData) stores settings, caches, and save data for a huge number of programs, and it can grow surprisingly large — browser caches and game save data are common offenders. Because so many apps hardcode a path to it, you generally can't use the Location tab trick here the way you can with Documents or Pictures.

Instead, moving AppData safely means creating a symbolic link (a junction point) using the mklink command in an elevated Command Prompt, which makes Windows and every app believe AppData is still at its original path while the actual files live on your other drive. This is a more advanced move than the four methods above — it's worth doing only if AppData specifically is your space problem, which you can check under Settings > System > Storage > Show more categories.

AppData is the one folder that usually needs a junction point rather than a simple move, since many programs expect it at a fixed path.

What Happens If I Just Drag and Drop a Folder to Another Drive?

For pure data folders like a folder of photos you manage yourself, drag-and-drop works fine. The problem is specifically with system-recognized folders like Documents or Downloads, and with installed programs — dragging those leaves shortcuts, registry entries, and other apps still pointing at the old C drive location, which is exactly what the Location-tab method and proper uninstall/reinstall process are built to avoid.

A simple rule: if it's a folder Windows itself created and tracks (the ones visible in File Explorer's sidebar), use the Location tab. If it's a folder you created yourself to hold your own files, drag-and-drop is perfectly safe.

Do This Regularly, Not Just Once

A full C drive tends to creep back over time — Downloads folders refill, new games get installed, browser caches grow — so treating this as a one-time fix rather than an occasional check tends to leave you back at "low disk space" warnings within a few months. Checking Settings > System > Storage every couple of months takes under a minute and catches the problem before it starts affecting update installs or app performance again.
