Exact File Size Matching

[gleporeNARA]

Some formats create files of a specific size, for example the DEGAS image format (http://fileformats.archiveteam.org/wiki/DEGAS_image) produces images of exactly 32,034 and 32,036 bytes. The signature of these files is either 00 00 or 00 01, which aren't specific enough to guarantee a match. However, a signature of 00 00 and a file size of exactly 32,034 would be enough to ensure a match.

It might not make sense to include file size as part of the PRONOM signature if it's only relevant to a small number of formats, but I thought I would throw it out there as a suggestion.
