LocalLow C:\Users\<utilisateur>\AppData\LocalLow

Local data of apps that run at a low integrity level (Protected Mode browser, sandboxed apps). Does not roam.

Updated on By AltF4 Formation

What it’s for

LocalLow is the low-integrity counterpart of the Local folder. Processes running at a low integrity level (a browser in Protected Mode, sandboxed components) cannot write to the rest of the profile, but they can write here. The folder is per user and per machine, and it is not synchronized with a roaming profile.

What it contains

  • Subfolders created by sandboxed applications: browser components, players and plug-ins, and some games or engines (Unity, for example, writes under LocalLow\<Publisher>\<Product>).
  • The known folder ID is FOLDERID_LocalAppDataLow, a per-user folder type with the default path %USERPROFILE%\AppData\LocalLow.
  • The content depends entirely on the installed applications.

Risks and best practices

  • Keep the LocalLow folder itself: the apps concerned need its low-integrity label, and a folder recreated by hand does not carry it automatically.
  • The subfolder of an uninstalled application can be deleted freely. For an application that is still installed, you lose its local data (cache, preferences).
  • The folder does not roam, so back it up with the rest of the profile if these apps keep useful data there.

Useful commands

Fenêtre de terminal
# Folder contents
Get-ChildItem "$env:USERPROFILE\AppData\LocalLow" -Force


# Check the integrity label (the "Mandatory Label\Low Mandatory Level" line)
icacls "$env:USERPROFILE\AppData\LocalLow"
