Why Samsung can’t just make snb files work with other programs is beyond me. If you don’t know what an snb file is, you are lucky……..but I’ll tell ya anyway. Samsung has a note taking program called S-Memo. While traveling, I thought this would be a good program to use for my journal writing as I could easily export the files to Drive, so when I took my daily trip notes, they could easily be backed up without having to always be connected to the Internet. Well, I was wrong.
Finding a program that could read S-Memo files on the PC is next to impossible. I Googled and Googled but couldn’t find an easy (or any) solution. Originally, I exported all the files directly to Drive expecting to be able to simply open and edit them but found that neither Drive nor any program on my PC could open the files. Finally by searching around on the Internet, I found that I could export from S-Memo under the “MyFiles” tab to either jpg, pdf or snb.
So obviously neither jpg or snb would be helpful as I wanted to edit my notes. I thought PDF was an option because on my computer, I have the full version of Adobe Acrobat. Unfortunately, this is not a real solution as the conversion basically gives you crap that you then have to decipher and put into actual words – much more work than just starting from scratch.
Overall, S-Note is a completely useless program and I will end up just reading my notes from my phone and will retype them.

Right you are! The trend is to force you to share (i.e. risking piracy / government inspection) them into the cloud to a samsung / other email inbox, by default activated synchronization. From there you can store and edit them. That’s current policy (Big Brother never has enough about spying on you – they need to know all about you – New World Order, so called).
Until Samsung and other manufacturers bent to NSA instructions give in and let people work cosy, try minimize absurd efforts by getting used to export text files to pdf and screenshot images right after you are finished with each snb file. Transfer them to your pc, using either folder-classification criteria to associate snapshots to pdf text-only files.
