Hello all,

One thing to add here is that Altium may produce two types of drill files, one in ASCII format (.TXT) and one in EIA-RS244 format (.DRL). The TXT - ASCII format is preferred since we can open, read the text & numbers, and resolve issues. The EIA-RS244 format is not readable in a simple text editor. See attached example...

Hello,

I have found some tables in the Altium help menu that lists the files that can possibly be generated as output from the PCB document in Altium Designer. In addition to the helpful information that is already here, please also review the images uploaded on this reply.

Lots of good information!
