how to copy a Default program to my PC?

[Luca]

Hello, i have a problem using my Hp Prime and i really wish you could help me:
I've copied the spreadsheet app and created a new spreadsheet saved with a different name in wich i've insered many functions (as i do in my pc through Microsoft Excel), does anyone know how to import this one in my pc?

I've already made these attempts:
-tried to connect trough the connectivity kit and copy the content of the new spreadsheet to a blank one created in my pc but, when i save it and close it, it doesn't save all the cells;
-tried to connect trought PrimeComm but this app saves only the hpappprgm apps and not the defaults such as spreadsheet or copies of it.

Please help me! Thanks!
