This is the software publisher’s description.

Bookmark Base is a portable bookmark database. What does this mean: probably you had a situation when you were working for a long time on two (home and work) computers simultaneously. After a time you will have two different sets of bookmarks on both of them.

You feed your base with bookmarks from both of those 'grey boxes'. Links are checked internally for duplicates and errors ('dead' links) and then you can deploy that merged set on any PC into any browser you like. All the time you just need to launch it, press 'Import' and here you go, all the new ones join the old stuff. The same way they can be exported to any PC.

It's easy and powerful: deploy it on your USB stick and carry everywhere you want. Launch it, import all bookmarks from one PC and deploy on another in seconds. Check your bookmarks for errors with fast internal checker.
