Windowsserverdocs: fsutil setCaseSensitiveInfo

[SoftWatchAdmin]

I tried running this command through powershell as admin:
fsutil.exe file setCaseSensitiveInfo <path> enable
but I keep getting an error:
The request is not supported.
I am running on an NTFS file system, as administrator.
Is this not supported on Windows 10 as specified in the documentation?

Hi @SoftWatchAdmin ,

Thanks for bringing this to our attention. We'll update this article ASAP with the following information:

You have to enable Windows Subsystem for Linux before this will work.

Run the following command as Administrator in PowerShell to enable this optional feature:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

You'll be prompted to restart your machine once it's installed. After your computer restarts, you'll be able to run Fsutil as Administrator in a command prompt window as you expected.

Here are a couple articles that explain in more detail:

Thanks,
Corey

Thanks for the feedback. I've updated the article with the info about the Subsystem for Linux requirement that @coreyp-at-msft mentioned above. Please let us know if there's other things we need to update. Thanks!

【fsutil file setCaseSensitiveInfo】This command can only open the case of the current file, and its sub-files are still case-insensitive. This caused me to fail to pass the case-sensitive check when compiling the Android source code on WSL. How to solve this problem? @lizap @coreyp-at-msft

Be ware though that enabling Linux Subsystem potentially prevents the Desktop (explorer) from loading. This happened in 1903 (19013.1). Disabling Microsoft-Windows-Subsystem-Linux feature rendered a working desktop.

Is there any chance The request is not supported. could be modified to provide actionable information? For example

The request is not supported. See http://aka.ms/setCaseSensitiveInfo for details on how to enable this feature for your device.

Hello,
This is confusing, At the top of the article, Windows 7 is also mentioned. But this requires WSL which is available on Windows 10 Only.
Thanks.
