<p>The first program was <b>NTFSDOS</b> - a freeware utility for DOS (<i>NTFSDOS.EXE</i>) that allows read-only access to NTFS formatted drives from a DOS environment.<sup id="cite_ref-NTFSDOS-Archive_4-0" class="reference"><a href="#cite_note-NTFSDOS-Archive-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

<p>The second program was <b>NTFSDOS Tools</b> - an add-on package for NTFSDOS that contains two commercial utilities for DOS - <b>NTFSCopy</b> and <b>NTFSRen</b>. The former (<i>NTFSCOPY.EXE</i>) could be used to overwrite corrupt files with fresh versions. The latter (<i>NTFSREN.EXE</i>) could be used to change the names of bad drivers so Windows could not load them.
</p>
<div class="mw-heading mw-heading3"><h3 id="Professional">Professional</h3></div>
<p>The final program was <b>NTFSDOS Professional</b> - a whole commercial solution for handling read and write operations in NTFS from a DOS environment. It must be installed as a package for <a href="Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> first.
</p><p>The downloaded version comes in <a href="Demoware" class="mw-redirect" title="Demoware">demoware</a> form. The user can only use the package in read-only mode in order to evaluate it.
