Theoretically, WhizFolders has the following constraints or limits. But you should also look at the practical tips given.
- The file size of a document should stay under 2 GB.
- A topic can be as large as a GB but it is not practical as it slows down the browsing (clicking on a topic to see it). Each person has a different perception of what is slow. You will find your own limit. When browsing the list becomes irritating, it is time to break the topic into several. In fact, the whole design of WhizFolders encourages breaking of information into pieces for easier management and reviewing. You can always join many (or all) pieces to make a large document to paste in a word processor.
- WhizFolders uses a very smart virtual listing technology to list the topics. The whole tree list is loaded without loading the text of names themselves. The names are obtained from the file and displayed dynamically as you scroll the list. Hence, the number of topics do not matter much. There is no limit as such on the number of parents, children, etc.
- The virtual scheme doesn’t put too much strain on memory too. The only objects in memory are the topic name pointers as above and the topic contents for only those topics which are being viewed or edited.
- There is no limit on number of topics but if the list is too large, it might slow down certain operations like adding a new topic where it has to resolve a unique internal name for it. You have to find your own limit depending on how the speed of operations affects you. We have even seen cases having more than 5000 topics in one file.
