URN = uniform resource name. It seems to relate to file transfer or "manifest" processes, which makes sense for a program that e-files.

"The statuses are used to verify whether the translation of requested output files is complete.

Note that different output files might complete their translation processes at different times, and therefore may have different status values.

When translating a source file a second time, the previously created manifest is not deleted; it appends the information (only new translations) to the manifest."

Whether ESET or Lacerte makes the .cfg file, ESET will know what it means and does and if you need them or they get recreated on the fly. Obviously, Microsoft Essentials no longer applies. Defender is now in use. Any AVG process needs to identify or have identified the programs in use and whether they are safe or not.

I recommend asking your own system person or ESET, if you need more help.
