Question: How to import this data file?

Dear power users, I have a probably trivial question. How can I import the attached file in Maple? The file consists of a header part with below the header two columns with data. The file coming from a measuring device has no extension and I could not upload it to the forum as it was considered a null file. In order to solve this I gave it a .txt extension but keep in mind that this normally is not present.

Additional question: if the file would have several headers each time followed by 2 data columns, is there an easy way to separate them in a sort of automatic manner?
