C 0000006 mmmv btree folder structure t1
This specification ended up to be FLAWED, because there might be less files than is needed to fulfill the B-tree requirements. Please refer to the C_0000007 mmmv_btreelike_folder_structure_t1 instead.
The idea is that the nodes of a B-tree are folders, folder names are keys, with the exception of folders named "root","leaf", and files have a key as their file name prefix, which is written as a base 10 positive whole number, including zero, followed by an underscore and the rest of the file name. The interpretation of the keys in non-leaf vertices is: "less than or equal to the key". bla-bla-bla-bla
