Data backup copying from one PC to another

 
Can anyone tell me how to update a new PC with the old Mt4/history data from the old PC. I've copied the old history files to the new PC Meta4/history folder but I still need to hit HOME several 100 times for the 1m charts to get back data. Why?? or what must I do to to reuse the old 1m file, specifically because the old files go back so much further??
 

Why not just copy the whole MT4 platform folder?
