    Hi. I have a very important file that I've been working on between a Mac and windows machine and saving on a USB. Today I opened it up on a MAC and then when I changed to the Windows machine it wasn't there. On the windows machine I made sure I could see hidden files and there I find the file now with the prefix "._", but windows won't let me open it. The normal file is not there just the file with the prefix. What can I do? I urgently need the file. What do y'all suggest? Thanks for your help!

    I'm a Mac guy, and know little about Windows.

    On the Mac, if there is a "." at the beginning of the file name, that file will be "invisible" in the finder. It's "still there", just not visible under normal circumstances.

    You can make invisible files VISIBLE in the finder.
    Sorry, I don't know the proper terminal command for this.
    Another way to do it is to download the utility named "Pathfinder" on the Mac.
    I believe it's free to try for 30 days.
    Using Pathfinder, you can set it so that all files are visible.
    You can then locate the "problem file", select it, go to Pathfinder's "file/attributes" menu, and see if you can make the file visible that way.

    As an alternative, I would suggest this:
    If you can see the hidden file on the Windows machine (even if you can't open it):
    Can you make a COPY of the file?
    Can you DUPLICATE it?
    The idea is to have a copy to work on rather than the original.

    Try that first.
    IF you can make a copy, work on the copy.
    If you have only the original, this may work anyway.

    What you want to do is to CHANGE THE NAME of the file.
    You want to GET RID of the "._" at the beginning of the name.
    You want a name that begins with a regular character (of the alphabet) or number.
    Are you able to do this?

    If so, take that to the Mac and see if it's visible in the finder.
    Is it?
    If so, try to open it.

    If it's a "very important file", one more suggestion for the future:
    Keep at least one backup copy of the file somewhere.
    One copy is not enough!
