    Title says it all. Basically, I reformatted my new flash drive to MS-DOS (which I think/suspect it was already) and files copied onto the flash drive become much larger. For example, a 275 megabyte folder full of images turned into a 425 megabyte folder-even when dragged off the flash drive.

    What could cause this? I do suspect that it's a labeling error, as the file doesn't act like it's gained size.

    Did you see the little label on the bottom of the flash drive, it says, "Files on this drive may be larger then they appear".

    Sorry, bad joke. I would say that it has to do with the sector size and it may be, but I don't think so, that typically only effects small files. Donno what to tell you, seems awful odd though.
