Computer network storage environment hostile to fault-intolerant electronic file types

A method for operating a network server to discourage use of server memory for fault-intolerant files, wherein the server is connected to a plurality of public clients and is operable to transfer public files between a memory of the server and the plurality of clients, wherein the public files comprise files of fault-tolerant types, and files of fault-intolerant types, the method comprising the steps of:

• selecting a file from a plurality of public files in a memory of the server;
• selecting a portion of the file, the selected portion comprising at least one bit of information in the file, wherein the file consists of the selected portion and a remaining portion larger than the selected portion;
• and
• altering the selected portion to create an altered file while leaving the remaining portion of the file unaltered, whereby the file is disabled for its intended purpose if the file is a fault-intolerant type and the file is not disabled for its intended purpose even while remaining altered if the file is a fault-tolerant type.

A system, comprising:

• a server adapted to connect to a network and to transfer public files between the server and a plurality of public clients, wherein the public files comprise files of fault-tolerant types, and files of fault-intolerant types;
• a processor operably associated with the server, the processor configured to perform the steps of:
• selecting a file from a plurality of public files in a memory of the server;
• selecting a portion of the file, the selected portion comprising at least one bit of information in the file, wherein the file consists of the selected portion and a remaining portion larger than the selected portion;
• and
• altering the selected portion to create an altered file while leaving the remaining portion of the file unaltered, whereby the file is disabled for its intended purpose if the file is a fault-intolerant type and the file is not disabled for its intended purpose even while remaining altered if the file is a fault-tolerant type.
