When another program, such as REGEDIT during an "Export...", is writing to a file, the command line FIND program give the infuriating File not found message. The problem is actually that the file is BUSY, and unavailable to be read by the FIND program. During REGEDIT's export to dump.reg (see the changing size of the file), we get this error message.
