 The machine that provides your Cloud Shell session is temporary and is recycled after your session

-in your session. The fileshare contains the image file that contains your `$HOME` directory. Only
-files that you upload or create in the `clouddrive` folder are persisted across sessions. Any files

+- If you chose the **No storage account required** option, you can only write files to your `$HOME`
+  folder.

+In both scenarios, you can write files to the `$HOME` folder. However, the `$HOME` folder only
+exists in the Cloud Shell container image that you're currently using. Files in the `$HOME` folder
