why do some illustrator and other adobe program files save as capital letters extensions? Typically they save as .ai, .psd, .ind, etc, but sometimes I see them as .AI, .IND, .PSD etc and with no thumbnail preview. The lowercase files display thumbnail previews with the correct Widnows image codecs but none of them display previews for the uppercase extensions, even file viewers such as Faststone and xnview.

All those files have been saved to the same volume?

And you created all of those files? Or did you build on someone else's files? Or templates?

None of the folders is a synchronized folder?

And the operating system also hasn't been updated?

Are they from UNIX or MS-DOS?

what does UNIX/MS-DOS have anything to do with Adobe?

 

files preview fine as lowercase ai but not always AI but for some reason save as capital AI rather than ai.
