Yes! A concept catalog could describe all the variants of a concept; in my [catalog entry for Upvote](https://forum.essenceofsoftware.com/t/upvote-sample-concept-catalog-entry/32), for example, I note how ranking works differently in Hacker News vs NYTimes. The concept of folder in Google Drive vs Dropbox is a very interesting one. In fact, it would be good to explore the design space of this concept for all these file sharing apps. I haven’t analyzed Google Drive in detail, but I did notice recently that two distinct files in the same folder can have the same name. This suggests Drive is not using the Unix Folder concept. A subtle difference that drew me to using Box for a task recently: if you put a file in Drive or Dropbox, then anyone who can view it in their browser can also download it (I think). But in Box, you can specify that a file can be viewed but not downloaded. This is a very useful feature; it can be used, for example, to share a PDF that you don’t want distributed by other means. --- _[View the full topic](https://forum.essenceofsoftware.com/t/comparing-similar-concepts-across-products/64)._
