I have some old projects in my android studio. I never need them. When I right-click on a project, I cannot find an option to delete, is it somewhere else?
How can I delete a project in android studio 3.5.4?
Open the .idea / modules.xml file and delete the module, then right-click on your module, you can see Delete ....
You should mark the project folder as excluded, as soon as you do this, you will see the “delete” option.
This method is explained in more detail in this link, which seems to be the same as what you are looking for.
