Firestorage is a network storage service from Japan. Due to Japan's good internet conditions, most Japanese online storage services either offer unlimited capacity or allow the upload of very large individual files. Firestorage, however, has both features: unlimited capacity and an impressive 2GB limit for individual file sizes. You can choose to register or not. Of course, if you do register, you'll gain additional management functions, such as the ability to delete files. Although it offers unlimited capacity, Firestorage emphasizes sharing over long-term storage, so files cannot be stored permanently. You can set an expiration time, such as one week, two weeks, one month, or other durations, or set the file to expire after a certain number of downloads.
