In computing, as well as in non-computing contexts, a file sequence is a well-ordered, (finite) collection of files, usually related to each other in some way.
In computing, file sequences should ideally obey some kind of locality of reference principle, so that not only all the files belonging to the same sequence ought to be locally referenced to each other, but they also obey that as much as is their proximity with respect to the ordering relation. Explicit file sequences are, in fact, sequences whose filenames all end with a numeric or alphanumeric tag in the end (excluding file extension).
The aforementioned locality of reference usually pertains either to the data, the metadata (e.g. their filenames or last-access dates), or the physical proximity within the storage media they reside in. In the latter acception it is better to speak about file contiguity (see below).
... When dealing with short files the savings are large percent wise ... Since that is not a valid file you would need to add something like BNN^AA
... A typical example where explicit file sequences, as well as their contiguity, becomes crucial is in the digital intermediate (DI) workflow for motion picture and video industries ... from either a digital video camera or a motion picture film scanner and stored into file sequences (as much as a common photographic camera does) and need ... Frame-per-file data management, because common post-production operations imply the shortest seek-times ever "fast-forwarding" or "rewinding" to a specific (key) frame is much ...
Famous quotes containing the words sequence and/or file:
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange formit may be called fleeting or eternalis in neither case the stuff that life is made of.”
—Walter Benjamin (18921940)
“While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.”
—Barbara Howar (b. 1934)
