A system and methods are disclosed for providing independent virtual drives of a hierarchical file system across any number of computers within a Wide Area Network such as the Internet such that the number of directories and files within these file system drives is constrained only by the amount of storage system hardware. The system and methods allow many file system drives to occupy the same storage hardware bu t be totally independent of each other and uniquely identified and privately accessed by a set of encryption keys. The system and methods store the files in these systems as many separate blocks that are distinguished by a unique identity, encrypted locally on the computer equipment during a write operation and are transferred to different computers for storage acros s a large Peer- to-Peer network. The system and methods transfer these blocks back and decry pt them locally on the computer equipment and reassemble them to reproduce the original file. The system and methods use an algorithm based on a one-way function that is executed locally on the computer equipment performing the read or write operation to determine the identities for each block and decide on which Storage Peer each block wi ll reside. This system and methods provide for a decentralized organization of the file sof the file system drive. Access to a file system drive, its directories and files can only be achieved with knowledge of this set of encryption keys. Many independent file system drives, both public and private, coexist on the same distributed storage hardware based o n different sets of encryption keys.
