Other than witness testimony, nearly all the evidence worth discovering in litigation is electronic. More often than not, it’s emails, text messages, database records, digital images, metadata, and Microsoft Office files that tell us the truth about what really happened. But there are several obstacles on the eDiscovery road to obtaining this valuable electronic evidence. One of the worst is the widespread practice of converting electronic evidence from its original, “native” form into some other form—and, in the process, degrading its ability to reveal the truth.
The typical alternative to producing native files consists of converting those files to TIFF images or PDF files, but sometimes producing parties will actually print out native files and deliver them in paper form. The upshot is that the requesting party receives a different file from what was requested and a different file from what was originally created by the requesting party or its agents. These differences are often profound: the converted files (or, worse, pages) are stripped of embedded data that frequently sheds light on the history and origin of the files (when they were created, who last edited them, etc.). Sometimes essential parts of the contents of the files will be truncated. I have seen printouts of spreadsheets where more than half of the columns were simply gone. Word documents often contain comment bubbles and records of tracked changes, and these can disappear entirely during the conversion process. Converting electronic files to a different form also provides a convenient way to hide key documents in an avalanche of unsearchable irrelevance. While native electronic files are generally text‑searchable, conversion frequently strips out searchable text.
An example of the type of metadata held within a .jpg image that would be lost if the image was converted to PDF.
It gets worse than just losing metadata. Native files are often searchable by their parts or “fields.” If you have to search through millions of emails, your job will be nearly impossible if you can’t perform searches that target certain senders and recipients. Native files include this functionality by default, but not so with converted files. And native files are cheaper to exchange because they are more compact than converted files. Take a Word file, print it out, and scan it to PDF at 250 DPI—you’ll see that the converted version is many times bigger than the original native file.
Procedurally, there’s a simple trick for getting native files—ask for them! It’s best to explain why you need native files at the earliest possible meeting with your adversary, to document your request for native files, and to include detailed instructions for producing native files in your document requests. If your opponent refuses to comply, it’s often worth your time to take the issue to the court. Discovery is about revealing the truth, and native documents serve this goal much better than degraded pseudo-copies in TIFF, PDF, or paper form.
When an opponent refuses to supply documents in native format, it’s very helpful to be able to make a strong case to the court on the evidentiary superiority of native files. To this end, I like to provide examples as part of my arguments.
Arguments like these are much more effective than generic assertions about the benefits of native files. Although many parties resist producing native files, when dealing with eDiscovery, it is often worth the time required to take a stand and to require an one’s adversary to produce in native format.
