    TRSTools is a utility that makes it easier to work with virtual disk images. My TRS-80 emulators, like most emulators, use virtual disk images rather than actual floppy disks or hard drives. Virtual disk images are representations of floppy and hard disks and contain the same information as real disks.

    Windows Virtual Floppy Disk Manager (GUI) v0.50
    Virtual Floppy Disk Manager (Command Line) v0.70     		August 14, 2010 Miguel Dutra VDISK Page
    This is a small utility which allows you to access virtual TRS-80 DSK/DMK images at a file level, as if they were normal PC disks. A virtual TRS-80 disk is actually a PC file encoded with information extracted from a real TRS-80 floppy, in order to preserve its content and also to enable its use with TRS-80 emulators.
    The TRS-80 Virtual Disk Manager shows the file name, size, date and attributes of each directory item, supports reading both .DSK and .DMK image files, and allows exporting TRS-80 files to the Windows file system.
    Notice that only read support is implemented at this moment.

    Windows Emulator File Read and Copy v3.1 2006 Phil Ereaut Home Site
    This program reads DSK files, and displays the disk filenames in a list box. Clicking on a file, allows the file to be saved to a PC folder. It can be used just to view the Files on a .Dsk, if you dont want to copy the files.

    It doesn’t always work, but it has definitely helped me extract files from DSK images which the emulator would not recognize.

    Windows Emulator File and Sector Display v5.0 February 1, 2009 Phil Ereaut  
    Mode 1:
         This program reads .DSK and DMK files, and displays the disk parameters, such as, Type of Emulator file, No of sides, Density, Tracks, Dual density, Tracks start at sector 1, etc. For Newdos disks, it will show the Pdrive paramters of the disk. You can step through, and view the sector information, and the sector density for Dual Density disks. Stepping a Newdos disk, the present lump will be displayed Clicking the directory button, will display the start of the directory. Stepping through the directory sectors will show the File names in the directory, and also in colour, the bytes, that show where the files are located on the disk.

    Mode 2: Sector display
         This mode displays the sector, numbers and Density, on each track, in numerical order, or in the actual interleave order. It also shows the sectors with differing Data address marks. Handy to see the tracks densities, and no. of sectors. On most disks, this can show the Directory sectors, but some early disks have weird combinations of data address marks.

    Mode 3: Hex Editor
         Will display the Hex and Ascii bytes of any file. This was a for myself, to have a look at the funny files that could not be read by the program. I left it in, as it may be handy for someone. For Emulator Dmk, and JV files, it shows the headers, Blocks, Idams, etc, in different colours to easily identify the set up of these files.
