A file is stored into the system by computing the hash of its filename.

The current algorithm for generating the unique filename combines the time, the host name, and a number of pseudo-random parameters to ensure uniqueness.
The filespec differs from the filename in that the filespec includes a complete specification, within a particular file system, of the file's location.
It is used similarly to the img tag and should be used with an image filename to display as the post background.
This number is also used in the filename of an associated clip information file zzzzz.clpi.
