Manipulating Files between a WSL Instance and Host Machine
Although WSL (Windows Subsystem for Linux) changed the game for developing on Windows, I inevitably will come across pain points in my workflow. One issue I frequently encountered was manipulating files between the host machine's drives and a WSL instance.
Manipulating files within a WSL instance
Let's say we have a file named
alice.txt located on a Windows drive with the file address of
C:\Users\<WIN_USER_NAME>\Documents\. To move the file to a WSL instance to the present working directory, run the following in a WSL terminal instance:
mv /mnt/c/Users/<WIN_USER_NAME>/Documents/ .
Note how they are essentially the same file path with just two key differences! First,
/mnt prepends any file address. Second, backslashes (
\) are swapped for slashes (
/). Now that we know this, we can easily leverage other file manipulation commands, such as
file, and so on.
Manipulating files in a WSL instance from Windows
Let's say we have the same file as before,
alice.txt, but we've moved it to the WSL instance and it now has the file path of
/home/<WSL_USER_NAME>/. To manipulate this file from your Windows host machine, the most straightforward way is to simply use File Explorer and navigate to
Here you'll see a folder for each of your WSL instances, where the folder names should map to the Linux distro that each instance uses (e.g. Ubuntu). Likely, you'll only have a single WSL instance so it should be simple to locate the correct folder. Navigate into the WSL instance folder, then
home, and finally
<WSL_USER_NAME>. Congrats, you'll find
alice.txt in this folder and can manipulate it accordingly!
You can even leverage the knowledge of these file addresses for CMD or PowerShell commands. To quickly check the current file address, simply right-click on the File Explorer address bar at the top and click "Edit Address" to display the file address in place or "Copy Address as Text" to copy the file address to your clipboard.
