If we update the android studio with the latest version and update the plugin as well. A folder named projectFilesBackup
created when we open our old android studio project in the latest android studio version.
My Question is why this folder created, why this is for and how long we should keep this folder in our project folder?
Android Studio stores the projects by default in the home folder of the user under AndroidStudioProjects. The main directory contains configuration files for Android Studio and the Gradle build files. The application relevant files are contained in the app folder.
The src folder holds two most important folders on any Android project, namely, androidTest and main. The androidTest package is created to hold Test cases for testing the application code and running. This folder contains . java (JAVA) files.
To change its path go to this path File > Settings... > Build, Execution, Deployment > Gradle In the Global Gradle settings Change Service directory path to what you want. Save this answer.
When you accepted to continue in the Convert Project dialog, IntelliJ created this file.
IntelliJ IDEA will back up old versions of project files to projectFilesBackUp folder within your project, so you could easily return to the old project version by replacing the project files with the old ones.
If the project is working correctly, you can delete the file.
