Atari800MacX Help
Disk Image Editor



The Disk Image Editor on the Atari800MacX emulator allows you to edit a ATR disk image that is formated with any of the supported Atari DOS formats.  You may Import and Export files from/to the Mac file system, as well as manipulate files and directories on the image.   The supported Atari DOS  types are Atari DOS 1.0, Atari DOS 2.x, Atari DOS 3.0, Atari DOS 4.0, Atari DOS XE, TopDOS, BiboDos, MyDos, SpartaDos 2+, and BWDOS.  When you select the Edit Disk Image menu item and pick a disk image to edit, you get a window like the one shown below.  You may open multiple disk images at once, and even drop and drag files between them.  You can open an image that is mounted in the emulator drive, but be very careful if you do, as the two processes may corrupt the image.  The emualtor should not be accessing the image when you change it.

Disk Editor Window

The Disk Editor has the following elements:

Image Type


The top of the file list view displays the type of DOS the image was formatted with.
Current Image Directory


This pulldown displays the current directory on the disk image.  If the image does not support disk directories, this will be MAIN.  You may navigate to a lower disk directory by double clicking on the directory name in the file list.  To navigate back up the directory tree, you may use this pulldown to select the directory to move to.
File List



This area lists the files in the current directory, in a format similar to that used by the DOS type for that image.  Files may be dragged and dropped to/from a Finder window to import/export the files.  Files may also be dragged and dropped between disk editor windows.  Dragging of Directories is not supported.

Free Space



This displays the amount of free space on the disk image in Kilobytes, not sectors or blocks.

Header Write Protect Bit Set In Image



This checkbox displays the state of the Write Protect bit in the header of the ATR image.  You may change it by clicking on the checkbox.  Normally, if this is set, it will prevent the emulator and other programs from writing to the image.  However, don't confuse this with the permissions on the file image in the MacOSX operating system, as they are separate.

Action Buttons



These buttons are used to perform operations on selected files in the File List.  If they are not active, it may be that no files are selected, the wrong file types are selected for the operation (directories), or the disk may be write protected, either by the operating system, or by the ATR header write protect bit.  (Note for a directory to be deleted, it must be empty.)

Linefeed Translation



This checkbox turns the translation of Atari Linefeed characters on or off for Import/Export operations to the Mac File system.
