I have a range of old mmp files, origing from MM4 or earlier. How do I convert these to mmap? I have tried the convert-macro (does not work) and have tried to open the maps with Viewer 3.5 but there I can not save as mmap.
You might be able to grab a copy of MindManager X5 from ftp://ftp.mindjet.com/MMX52-E-347_Pro... see if it can import the files? MMX5 should then be able to create mmap-files which are the newer generation files.
