I've been using various versions of MacLinkPlus since the 1990s. It used to be much more necessary to translate file formats between Mac and PC, but these days, it's less needed. MS Office and OpenOffice apps have many built-in file translators, GraphicConverter handles many graphic formats, etc. The current version 16 is a disappointment for a couple of reasons,. First, in spite of its 2007 release date, it's still a PowerPC app (runs on Intel Mac with Rosetta). Second, It comes with two added programs, icWord and icExcel, that are supposed to let you open Word and Excel files without MS Office, although when launched, they say they only work with version 15! Not really needed, though, as one can use a free OpenOffice-based program.
The main reason I continue to use it occasionally: it can open and translate early versions of Mac Word and Excel files that the current version of MS Office cannot open.
