@peterlemer I use Evernote in the situation you are describing. A big benefit you will have is that if you would (as an example) store License info of programs you have purchased in Evernote, if you need to access this information elsewhere - or in another platform, you will always have this information at hand and it wont be lost in case of a hard disk fault..

You can make your data hierarchy very neat in Evernote as well and it even supports tagging.
