Hi Jens. Thank you for your advice. I am planning on contents of folders to be no more than 2000 items maximum and using CMFBTreeFolders for larger folders consistent with your recommendations.

I am using CMF 1.5.2 and Zope 2.8.0 - will upgrading again this week to 1.5.3 and 2.8.1 I removed my BTreeFolder2 product as it was indicating it was duplicated product in my event log after my recent upgrade - so it appears to have become part of the distribution.


I did not really understand the difference between a BTreeFolder2 and a CMFBTreeFolder since CMFBTreeFolder did not appear as content even though it is displayed as an option in Core Content in ZMI. So my content was appearing on the web but not visible in the portal as a folder. I guess I am wondering why isn't it ready to go by default as a core type in CMFDefault. It appears everything is there except registering in types tool. My opinion is it would be really great if it were included as a core type (in the sense it is ready to go as the other types are). It could also remove confusion in ZMI that Core Content will produce content that is immediately recognized by the portal. Many thanks.

Regards,
David

How many objects should one have in a single folder to consider using BTree Folder over the regular Folder? Does it make sense to use a BTree folder for 100 - 500 objects or should it be reserved for situations where there are say 1000 + objects or more. Are there any benefits to be gained at the lower end as well or are there >> drawbacks?

I would use them with 100 and more items.


On another note, why do CMFBTree folders not appear in CMF? Is this the way they are supposed to work? If so, what differentiates them from a BTreeFolder2 if they are not a type visible to CMF?

Do you have the BTreeFolder2 product installed? Only then can you instantiate and use the CMFBtreeFolder type in the types tool.
