A 256 GB system SSD that felt roomy in 2020 fills up fast in 2026. Windows Update reserves its slice, browsers cache aggressively, and Documents alone can pass 200 GB once a few years of screenshots, saved games, and OneDrive-synced folders pile in. The obvious fix is to drop in a bigger second drive and shove the user folder over to it. The obvious method — dragging C:\Users to D:\ in File Explorer — is exactly how people end up with a broken OneDrive, dead Start Menu shortcuts, and app updaters that can no longer find their config. The best apps for moving Windows user folder data do the same job atomically, keep permissions intact, and leave Windows convinced nothing changed.
We tested the seven tools below across a small system SSD (Documents at 210 GB, AppData at 38 GB) and a 2 TB target drive. The right pick depends on how much you want to move, whether you need AppData to come along, and how comfortable you are with the command line.
What to look for in a user-folder migration tool
Five things separate a safe migration from a weekend of Windows repair:
- Atomic vs partial moves. A tool that copies and swaps in one pass will not leave you with half a Documents folder if the power drops. Robocopy with
/MIRand User Profile Wizard both fit this shape. - Symlinks vs true relocation. Symlinks (junction points) leave the folder path at
C:\Users\You\Documentsbut store the bytes on another drive. True relocation moves the path itself. Symlinks are less risky because Windows still sees the old path; relocation is cleaner but every app that hard-codes the old path breaks. - Rollback ability. Any tool worth using either keeps a copy until you confirm the move, or writes a manifest you can reverse. Drag-and-drop offers neither.
- Permissions preservation. NTFS ACLs and ownership must survive the copy or Windows will start throwing access-denied errors for its own files. Robocopy’s
/COPYALLflag and dedicated migration tools handle this. File Explorer alone does not. - AppData handling. This is where most cheap tools fall over. AppData holds per-app config, browser profiles, and license state; some apps write to it while running and lock the files. The safest tools either move AppData at boot before user services start, or skip it entirely.

1. User Profile Wizard by ForensiT
The tool most admins reach for first. User Profile Wizard was written to migrate Windows profiles between domains, but the same engine cleanly moves a profile from C:\Users\You to D:\Users\You and updates every registry pointer Windows uses to find it. AppData, NTUSER.DAT, permissions, and per-user services all come along. Because it edits the profile list in the registry, Windows treats the new location as the canonical one after reboot — no symlink, no dangling reference.
The Personal Edition is free for non-commercial use. Run it from an admin account other than the profile you are moving, point it at the target drive, and let it finish before signing back in as the migrated user. This is the tool for anyone who wants the full profile on a new drive with no shims left behind.

2. EaseUS Todo PCTrans
If a wizard-driven, paid product is closer to your comfort zone, PCTrans is the strongest of that class. It handles three tasks the free tools do not combine well: moving installed applications with their registry entries intact, migrating user accounts and their AppData, and copying data folders in bulk. The interface walks through source and target drives, shows a size estimate, and reports which apps it can move versus which need to be reinstalled.
The free tier caps how many apps you can transfer per run and how many user accounts it will migrate. The paid tier lifts those caps. It shines when you are moving to a new system drive and want everything to keep working without hand-editing paths.

3. Steam Mover
The small, portable utility that started life for Steam libraries but works on any folder. Point it at a source path, pick a target, and it copies the folder to the new drive and drops a junction point at the old location. Windows and every app still see the folder at its original path — the bytes just live somewhere else.
It is the fastest way to relocate individual heavy folders (Downloads, a specific game library, a Photos subfolder) without touching the rest of the profile. Because it uses junctions rather than editing registry pointers, you can move a folder back later just as easily. Not the right tool for moving the entire C:\Users\You tree at once, but excellent for the 10 folders that account for 80% of your disk use.

4. FolderMove
Open-source, single-executable, and does exactly one thing: moves a folder to another drive and leaves a junction behind. FolderMove is what Steam Mover would look like written for 2026 — cleaner UI, no configuration to think about, source code you can read before running it as admin.
Reach for FolderMove when you want the Steam Mover workflow but prefer an actively maintained open-source project. It is small enough to run from a USB stick when helping someone else migrate.

5. Junction Link Magic
A GUI for NTFS junction points. Where Steam Mover and FolderMove both create and manage junctions as part of a folder-moving workflow, Junction Link Magic is the tool you use to see every junction on your system, create new ones by hand, and delete old ones safely.
It matters when a migration goes sideways. If you moved a folder with a script that left the junction pointing at the wrong path, or you inherited a machine with junctions scattered across drives, Junction Link Magic gives you a clean view and a way to fix them without hunting through Command Prompt output. Keep it in your recovery toolkit rather than your daily driver.

6. Robocopy
The safest baseline for any data-only move. Robocopy ships with Windows, runs from an elevated Command Prompt or PowerShell, and preserves NTFS permissions, timestamps, and ownership when called with the right flags. The canonical command for moving a folder is:
robocopy "C:\Users\You\Documents" "D:\Users\You\Documents" /E /COPYALL /DCOPY:T /R:2 /W:5 /MT:16 /XJ /MOVE
/COPYALL carries permissions, /DCOPY:T preserves directory timestamps, /MT:16 parallelises the copy, /XJ skips existing junction points so it does not loop through symlinks, and /MOVE deletes the source after a successful copy. Drop /MOVE for a first-pass rehearsal that leaves the original intact until you have verified the target.
Robocopy is not a migration wizard — it will not update Windows to look at the new path. Pair it with a Documents/Downloads Change-Location edit (see the built-in method below) or a junction and you have a bulletproof workflow. Anyone who distrusts GUI installers should start here.

7. AOMEI Backupper
The right tool when the answer is not “move a folder” but “replace the whole system drive.” AOMEI Backupper clones a live Windows installation to a larger disk, resizes partitions during the clone, and produces a bootable target you can swap in. Everything on the old drive — Windows, apps, profiles, AppData — ends up on the new one at the same paths.
The free tier covers disk clones and system backups. Use it when the migration you actually want is “same setup, bigger drive” rather than “user folder on a second drive.” It is overkill for moving Documents alone and exactly right when the system SSD is on its last legs.

Bonus: the built-in Change location
Every user library folder in Windows 11 — Documents, Downloads, Music, Pictures, Videos — has a Location tab in its Properties dialog. Right-click the folder in File Explorer, open Properties, switch to Location, type the new path (e.g. D:\Users\You\Documents), and click Move. Windows copies the contents, updates the shell folder registration, and points every “Save As” dialog at the new drive.
This is the safest single method for the five libraries that account for most user data. It is officially supported, survives Windows Update, and does not use symlinks. The catch: it only works for those five folders and a handful of others (Desktop, Contacts, Favorites). It does not move AppData, and it will not relocate the profile itself. For a partial move that covers the biggest folders without any third-party tool, this is the answer.
How to pick the right one
If you only want Documents and Downloads on a bigger drive, start with the built-in Change location on each library folder. It is officially supported, needs no download, and covers the majority case.
If you need to move an entire user profile including AppData and per-user services, User Profile Wizard is the right pick. It is the only free tool on this list that updates the registry pointers Windows uses to find the profile, which is what makes it work cleanly across reboots.
If you want a wizard-driven paid tool that also migrates installed apps, EaseUS Todo PCTrans is worth the licence. It is the fastest way to end a migration with your apps still opening from the Start Menu.
If you distrust GUIs and want an audit trail, Robocopy from an elevated prompt is the baseline. Pair it with a Change location edit or a manual junction and you have a fully reversible workflow you understand line by line.
If the real problem is that the system SSD itself is out of room and slow, clone the whole drive with AOMEI Backupper rather than shuffling folders. It is a different job and cheaper than a week of piecemeal moves.
FAQ
Can I move C:\Users to another drive without reinstalling Windows?
Yes, but not by dragging it in File Explorer. Windows keeps registry pointers to the profile path in dozens of places, and OneDrive, some Microsoft Store apps, and various updaters break when those pointers stop matching. Use User Profile Wizard to move a full profile with the registry updated, or move individual folders (Documents, Downloads, AppData sub-folders) with junctions from Steam Mover or FolderMove. Both approaches leave Windows convinced the profile still lives at the original path.
Will moving my user folder break OneDrive?
It can. OneDrive stores its sync root path in the registry and complains loudly if that path changes without its knowledge. Two safe patterns: sign out of OneDrive before the move, then sign back in and re-select the new folder as the sync root; or use a junction (Steam Mover, FolderMove) so OneDrive still sees the folder at the same path. Moving OneDrive itself via its own settings (“Change location” inside the OneDrive app) is safer than any third-party tool for that specific folder.
What is the safest way to move Downloads to another SSD?
Right-click the Downloads folder, open Properties, go to the Location tab, and use Move. This is the officially supported path — Windows copies the contents, updates the shell folder registration, and every browser and app that respects the standard Downloads path follows automatically. It takes about two minutes and needs no third-party software.
Do symlinks slow down disk access?
Not measurably. NTFS junction points and symbolic links resolve at the filesystem layer with a small one-time lookup, and the actual reads and writes happen on the target drive at full speed. A folder junctioned to a fast NVMe drive is as fast as native access on that drive. The slowdown people notice is almost always because they junctioned a heavy folder to a slower drive, not because of the junction itself.
Can I move AppData to another drive?
Yes, but be careful. AppData holds per-app config, browser profiles, and license state, and some apps hold files open while running. Use User Profile Wizard for a full-profile move that includes AppData atomically. For a partial approach, move specific sub-folders (a single browser’s profile, a single app’s cache) with a junction while the app is closed, then start the app and confirm it still finds its data. Never move the whole AppData folder while apps are running — you will corrupt state.
What happens if I move a folder and later delete the source?
If you used a junction (Steam Mover, FolderMove, Junction Link Magic), the source location is the junction and the target holds the bytes; deleting the source removes the link but the data survives. Do not delete the target — that erases the actual files. If you used a true relocation (User Profile Wizard, Robocopy with /MOVE, EaseUS PCTrans), the source no longer exists; the data lives only at the new path. When in doubt, run a Robocopy pass without /MOVE first, verify the target, then delete the source manually.
