You don't specify what OS you're using, but I'd suggest something from
the general class of disk encryptors. These programs keep your file
permanently encrypted, but still allow you to work with it. As your
application program tries to read each portion of the file, that
individual portion is copied to RAM and decrypted in RAM. The hard drive
is _never_ decrypted. In general, they're no more difficult to use than
logging in to a network drive.
For Windows, either PGPdisk or Secure Drive.=20
For UNIX/LINUX, try CFS (Cryptographic File System) or TCFS.
