A digital locker is a virtual vault that facilitates online storage of documents and files such as videos, games, music, movies, etc. Based on cloud computing, digital storage facilitates anytime and anywhere access to the files, provided there’s a reliable Internet connection. A digital locker membership could be free or premium. The locker can be accessed on the web (browser) or via a software application. Such lockers could be privately owned or through a government initiative, such as DigiLocker.

Microsoft first used the “digital locker” term to denote purchased applications that users can access or download whenever needed from its servers. For instance, downloading and installing already bought software tools onto a new computer. The system ensured customers didn’t have to buy software in physical forms, such as DVDs and CDs. This made storage convenient and decreased risks of damaged or lost discs.
