Question

I have a .dld dataset file I need to access the data but I have no idea how to do that, apparently the file is compressed using quickLZ compression.

I can see the compression type when opening the file in the text editor, it looks like this:

<dataitem version="2">
  <m compressor="quicklz_151b7" seekable="N">
    <b k="block_sentinel">h3h693CzdALgDbqAJvoyLw==</b>
    <l k="orders">
      <l>
        <m field="location_id" order="ascending"/>
      </l>
    </l>
    <l k="schema">
      <m name="location_id">
        <m k="datatype" size="20" type="TextVar"/>
      </m>
      <m name="contact_id">
        <m k="datatype" size="20" type="TextVar"/>
      </m>
      <m name="email">
        <m k="datatype" size="254" type="TextVar"/>
      </m>
      <m name="email_update_source">
        <m k="datatype" size="64" type="TextVar"/>
      </m>
      <m name="company_email_flag">
        <m k="datatype" size="64" type="TextVar"/>
      </m>
    </l>
    <b k="tail_sentinel">ho+N0padvwkvbrM3o3kNwQ==</b>
  </m>
</dataitem>

the rest of the content is scrambled, can't make any sense of it. I have tried decompressing using http://www.quicklz.com/download.html on C# but no result
