projectFilesBackup folder in android studio project for latest version -


if update android studio latest version , update plugin well. folder named projectfilesbackup created when open our old android studio project in latest android studio version.

my question why folder created, why , how long should keep folder in our project folder?

when accepted continue in convert project dialog, intellij created file.

intellij idea old versions of project files projectfilesbackup folder within project, return old project version replacing project files old ones.

if project working correctly, can delete file.
