    How do to change a file's "kind" in Finder?
    I have some PNG files and even though they all have the same ".png" extension, they have different values in the "kind" column in finder. Some of the files are:

    "Portable Network Graphics images" while others are
    "Adobe Photoshop PNG file"

    This is an issue because when sorting by kind, I expect all my PNGs to be together and instead they are apart due to their different "kind" values.

    How can I change the "kind" property of a file? Take note, changing the "opens with" property under "Get Info" does not change file kind.

    well Portable Network Graphic is what the PNG is, but how were the files created? I'm thinking they might have different color depth, the Adobe PS PNG having a higher depth?

    PNG supports both 8bit and 16bit color depth, try resaving your images

    still, just a wild guess

    Thanks for the reply scathe, I actually tried resaving the photoshop png in Preview before and that actually did change the kind value to "Portable Network Graphics image"

    but I feel like that's a bit of a workaround specific to PNGs and am wondering if there is some sort of general solution to edit a file's kind value for any file.
