Hey folks, anyone know of a file format with a .pry extension? An archivist pal received something on a floppy disk (date on label is 1999 if that helps). PRONOM is drawing a blank.

@sarahromkey huh, complete blank from TRiD and the File Formats Wiki as well:


@sarahromkey Guessing they tried Siegfried, etc? This wasn't too useful but maybe worth comparing some of these files?

@sarahromkey most stuff seems to point to debugging sessions like ruby's pry, but I'm pretty sure it didn't exist back then; other information says some sort of binary format. Might be best to open it with a binary / hex viewer, might give more clues — Good luck!


Would there be help via Reddit? (Not much of a geek, but they can be amazing over there.) Or perhaps this site?

@sarahromkey #PRY Seems to be simple text from 'Catholic Prayerware for Windows V1.0 '


WINPRAYR.ZIP 176.7 KB 1994-11-23 Catholic Prayerware for Windows

Example: File Content: 1MRNGBRF.PRY
Morning Offering - Brief

Heavenly Father,

I offer you this day all that I shall think or do or say,

uniting it with what was done by Jesus Christ, your only Son.


@Jethrotombs this must be it! The file was found by a colleague who is the archivist for a Catholic order of nuns. Thanks so much!

@sarahromkey I commonly made up extensions for TXT files, like .poe for poems or .jrn for journal entries. Have you tried a text editor?

@sarahromkey There's a tool for Ruby programming called pry, and I know it can use a binding.pry file. Ruby is from 1995; I wonder if pry once had more file handling?

Alternatively, a typo or alternate version of .py?

@kalany It was, believe it or not, from something called "Catholic Prayerware for Windows." This makes sense in the context of the archivist working for a Catholic order of nuns!

@sarahromkey Might be worth saving a copy on a Unix machines (Linux/BSD/etc.) and see if the file command can make any sense of it. Also, is it possible the extension is a typo? Maybe it was supposed to be .prt, or .pr, or something else.

@sarahromkey The extension may not explain the whole picture, the content is what tells what it really is. I suspect some proprietary internal format. You may have to do some reverse engineering to figure out what it contains. Have any history on what it might be for, like who was the previous owner?

@mctwist Hi, thanks for your reply, it was figured out using that kind of context actually.
