"Export" is a function built into the SNote app...it has native "conversion" capabilities with formats accessible by PC based programs (again, jpg/pdf).
turned out not so good.
first advise was to change the file extension to ZIP. Did that, but WinZip didnt' turn it into anything readable.
second, linked/referred me to a for-purchase program from a company called FileViewPro.
was finally able to convert them to .txt files on my own on Google drive, and download them to the Internal Storage on my new phone.
Unfortunately, "Quick Memo" is not reading/importing them from there.
This is not an easy transition to my new phone.
