The old timers have retired. There is a subdirectory under our Blocks directory that contains what appears to be block-associated file with a .INF extension and file dates around 1992. Some but not all have a same name .ATT file. Almost a certainty that these are obsolete. Can't find any info on the web. Anyone know what these extensions represent? The file names don't align with our current blocks but hate to delete something that might be needed to open an old file (but highly unlikely).

can you open the inf file in a text editor to see if you can get any more information?

Back in those early DOS days you can name files with practically any extensions you like and that includes text files. So try opening these with Notepad and see if they are legible
I don’t recall any AutoCAD DOS releases using any of these types of file extensions. Perhaps it might have been a third party app. I would say it’s safe to trash them
