What is the extension of a Android Studio project file?
Opening a saved project on another drive There is no such single project file that needs to be opened but rather the directory where the whole project is stored.
- Find the directory where you have saved your project
- In Android Studio -> Files -> Open->(click on the directory name where your files/project is stored)
Use the import project function on the build.gradle file in your project root (not the folder itself!) to open the project again in Android Studio.
I think ".iml" is the extension for Android studio projects. ".project" is for Eclipse projects
