I've just put this complete thread as a link into my Netsso, to study later. If I want to avoid future link rot, I tell Netsso to "save content" to my Dropbox/ GoogleDrive/OneDrive. In doing that, I could also click to encrypt each file separately, with a 40 character unique password,that only I know, and only decrypts on my local machine. Netsso remembers the passwords but only I know them !.It stores any type of document, any url. I load files from my computer to my Dropbox, and immediately link them to my Netsso, so I can access them on any device without formally opening the Dropbox. Online Note-making, with rich text, images included, even videos. Save any new urls with quick click/copy/paste. Add 400 character description to a link, to include in later search. Very sophisticated categorisation, sharing (even encrypted notes), drag/drop, inbuilt credentials for apps, etc (i.e password management included)...8000 links so far. Preview or Open on line, download, edit. Also I have a sharing version for Teams, with same functionality (plus encrypted Chat). Built for private,personal use - all my web knowledge available anywhere- but very easy to share links, or collections of links, if required. I can also Back Up complete collection to any computer in seconds, encrypted by my master password. Netsso seems to be a unique combination of bookmarker, online file creator and manager, internet file security enhancer and team collaborator.
