Don, do you have personal experience with file deleting via the computer causing problems? I would never format a card with the computer - I always format a card in the camera it's to be used in - but since the dawn of digital I've been deleting, adding, moving files to/from cards via the computer and have never seen a problem doing so. That's with many cameras, many OS's, many computers, and many card form-factors - compact flash, sd, sdhc, micro-sd, etc. Jeff > > There is one warning I would give in any case- Never try to use the computer > to delete a photo from the card, whether the card is in the camera, or in > the computer slot or card adapter.
