    /// <summary>
    /// TZCopyProtection allows users to alter image files so they can be used to burn copy protected CD-Rs.
    /// It does this through multiple "steps", all of which can be applied independently of one another.
    /// Step 1 shifts the data of the first track into "track 0".
    /// Step 2, seemingly, moves the data of a selected file to a second data track, with a configurable amount of empty audio tracks inbetween data tracks.
    /// Step 3 pads the filesize of a specified file to a specified length, creating a dummy file.
    /// Details on how these steps work: https://web.archive.org/web/20011107003900/http://jove.prohosting.com/~tzcopy/dev.html
    /// Worth noting is that all of these features aim exclusively to prevent the protected CD-R from being copied, there are no program/driver/etc. files added to the modified image whatsoever.
    /// Due to this, it's unlikely that these earlier versions are able to be detected whatsoever.
    /// 
    /// After V1.1 Beta 9, the original author released the source code, retired from the project, and allowed others to continue the project (https://web.archive.org/web/20030619042134/http://www.tzcopyprotection.tk/).
    /// Several others began to contribute, with features such a new GUI, new protection steps, new image formats supported, etc. being added.
    /// Step 4 uses a "ghost" file that is added to the CUE and intended to be present during the start of burning a CD-R, but then modified during the burn so that there are intentional errors at the end of the disc.
    /// Step 5 adds "weak, damaged and hidden sectors" (https://web.archive.org/web/20030205103207/http://snow.prohosting.com/~clone99/tzweb/faqs.html) to the image.
    /// In my experience, V1.5.4 was far less stable than V1.11.1.4, with the latter having fewer newer features in comparison.
    /// There's also a program made by this team called "TZ EXE Protector".
