Mike —
yes, parts of C:\Users can be moved, but
moving the entire Users folder on an existing Windows install is not recommended.
That usually causes trouble with:
- Windows updates
- Microsoft Store apps
- profiles
- permissions
- future repairs/upgrades
Short answer
Do not try to move all of C:\Users manually
The safer approach is:
- Move the big user folders
- Move OneDrive/Downloads/Desktop/Documents/Pictures/Videos
- Redirect temp folders
- Find what inside AppData is bloating C:
Best safe options
1) Move your user folders properly
For each of these:
- Desktop
- Documents
- Downloads
- Pictures
- Music
- Videos
Do this:
- Open File Explorer
- Go to
C:\Users\YourName
- Right-click the folder, such as Downloads
- Click Properties
- Open the Location tab
- Click Move
- Choose a folder on
D: or F:
- Let Windows move the contents
That is the
supported way to move the biggest parts of
Users.
2) Move OneDrive if you use it
OneDrive often eats space under your profile.
- Right-click the OneDrive icon
- Open Settings
- Unlink this PC
- Sign in again
- When asked for the folder location, choose a folder on
D: or F:
3) Move browser downloads/cache targets
Browsers often keep a lot under
Users.
Chrome / Edge
- Open browser Settings
- Change Downloads location to
D: or F:
- Clear browser cache
4) Move TEMP and TMP
This can help, especially if Adobe or installers dump a lot of junk there.
User temp
- Press Win + R
- Type
sysdm.cpl
- Open Advanced
- Click Environment Variables
- Change TEMP and TMP under your user account to something like:
- Create that folder first
- Reboot
System temp
You can also move the
system TEMP/TMP, but do the
user ones first.
5) Find what inside Users is actually huge
The real problem is usually not the obvious folders — it is often:
C:\Users\YourName\AppData\Local
C:\Users\YourName\AppData\Roaming
- browser caches
- Adobe caches
- installer leftovers
- game launchers
- crash dumps
Best way to check
Use a size scanner such as:
Then look specifically at:
C:\Users\YourName\AppData\Local
C:\ProgramData
C:\Windows\Temp
If you want, I can help you interpret the results safely before you delete anything.
About moving the entire Users folder
Possible? Technically yes.
Good idea on an already-running system? No.
It is the kind of change that can leave you with:
- broken logins
- broken updates
- broken app permissions
- weird profile issues later
If someone truly wants
Users on another drive, the clean way is usually done
during a fresh Windows install, not after the fact.
If C: is still critically low
Since your C: only has a few GB free, I would do this next:
1) Check AppData
- Press Win + R
- Enter:
%localappdata%
- Sort by size
- Look for giant folders
2) Check temp folders
- Press Win + R
- Enter:
%temp%
- Delete what will delete
- Skip files in use
3) Check ProgramData
- Open:
C:\ProgramData
- Look for large app caches
My recommendation
Do this first
- Move all standard profile folders with the Location tab
- Move OneDrive
- Move TEMP/TMP
- Scan
C:\Users with TreeSize or WinDirStat
Do not do this first
- Do not manually drag the whole
Users folder to another drive
- Do not rename profile paths in the registry unless you are prepared for breakage
About the R problem
And yes — your
UseRs /
DRive typing here is more evidence that the issue is
this forum editor, not your keyboard. Since you already proved the
search box works but the
post editor fails, that still points to the site editor specifically.

Users, or

AppData is filling C:.
