Hi, I've copy the whole directory of an application which contains a lot of .d files, some of them around 90 MB of size. Are these files Progress tables or files? How can I import this files to manage the data and migrate it to a MySql DB? How can I open .D files? In addition there's .I and .AT files, which I totally don't know what kind of files are or how can I open it...? Thanks in advance.
