Computer Folder, Closed Folder
This is a yellow folder, maybe you are very familiar with it, because when you open the computer to manage your files, you will see it.
It should be noted that if you are using an Apple system, or you are using Twitter, it is not yellow, because Apple and Twitter design it as gray and blue respectively.
Folders are used to store various files, compressed packages, programs, etc. on the computer or mobile phone. Therefore, the emoji can be used to specifically refer to computer files. In addition, it can also mean organizing, office, and work.
