We were staring at an obsolete format definition: “ A format, which, within our limited resourced world view at the time, we could no longer use.” Confirmation with the content provider gave us the original environment as OS/2.īut that was it. a potential font size and title, ‘Roman Bold 26’, and a few more Google searches meant that we could say these files were potentially proprietary to an IBM system as opposed to a file with a more open specification. With neither identifying the files the search really begins with a Google search of the file’s magic bytes:Ī single result at the time provided little to go on it confirmed someone had once asked the same question on a computer graphics forum. Recently I was asked by a colleague to look at some files he’d been sent by Hutt City Council in New Zealand an unknown format from a 1995 vintage IBM operating system – a format as yet unidentified by popular format identification tools.Īs with most of these attempts to identify a format we ran the files through DROID, ExifTool and the Unix File Command. ” #Migration: No one does it for the future they do it (need to do it) for the now.” –
