为什么Android Studio项目文件如此之大?

好吧,我的开发笔记本电脑在项目中期就出现了故障。我通常将项目保存到OneDrive,所以当我在OneDrive上看到文件完好无损时,我感到很放心。因此,我跳到另一台计算机上并开始同步OneDrive,以便继续进行项目开发。我以为那是完美无瑕的...

Believe me, this is 12 hours. No headway. Presently, all the files are synced to the local OneDrive except this 'build folder'. It is still syncing. OneDrive infinite Sync

Trying to get Android Studio to open the project anyway was a waste of time. It will not finish importing the project, it's stuck on 'indexing'. I decided to download the build folder manually from the web Onedrive. It indicated 63.8kb... Well, this is one hour the supposedly tiny file is still downloading 'infinitely' now at 128mb! manual download of project files This is entirely frustrating. Can anyone help me out here? How can I get my project up and running again?
