If you have any important software serial code over a notepad and you have collected after a hard find searching, then you need to keep that file archive over the internet. Archiving your notepad file online is very helpful. As computers cannot be trusted all the time because its hard disk can get crash anytime and you can lost your files or those notepad file which may consists of important writings,passwords, code which you kept for later use.
I mainly use esnips to keep my notepad files archive and keep the tension of getting deleted away from my brain. You may use other file hosting sites to keep your important word files undeleted.
