I need to transfer an Atari program downloaded from the internet using my Mac Mini. I can transfer it to my old PM7100 where I want to put it onto a DOS formatted 720k floppy that the Atari can read. The problem is Mac OS adds invisible files making the data too big to fit on the floppy. I am wondering if I can delete these files on the Mini and transfer to the 7100 over ethernet without the invisible files being re-written.

    You won't be able to make them visible because they don't exist until you try to copy them to a file format that doesn't understand metadata. Then, Mac OS X creates the ._ files to store the metadata on that file system.

     

    Use ditto in the Terminal to copy the files:

    ditto -norsrc path/to/source destination/path
    

     

    The command to make files visible is:

    chflags -nohidden path/to/file

    Thanks Barney. I am not a terminal expert, it scares the life out of me to be honest. If I understand you right, I can use this method and get a copy without the invisible files? How do I find the folder I need to modify in Terminal?

    I'm not sure what you're asking.

    You don't need to modify a folder at all.  If you have files on the floppy you need to see to delete, type "chflags -nohidden " in the terminal, no quotes and leave a space, then drag the floppy volume (Finder, go Computer) into the Terminal Window.

     

    To copy with ditto, open Terminal and type "ditto " without the quotes. Note that I left a space after ditto. Now, drag the files you want to copy into the Terminal window. Now, drag the destination folder into the Terminal. If that Is on an external floppy drive, then you can find that folder by going to the Finder, Go menu, Computer.

    Hit return. It will copy all of the files to the floppy without the resource forks (which are what makes the invisible files).

     

    If you have files on the floppy you need to see to delete, type "chflags -nohidden " in the terminal, no quotes and leave a space, then drag the floppy volume (Finder, go Computer) into the Terminal Window.

    If you don't like using Terminal, then download Onyx for your OS from http://www.titanium.free.fr/download.php Navigate to Parameters>Finder and then click on the box in Misc Options to "Show hidden files and folders".

    In Snow Leopard 10.6.8, to make a file(s) visible, this worked for me (omitted the dash from previous instructions by Barney-15):

     

    chflags nohidden path/to/file
