I would agree that pdb is more like a container format. It is certainly not a file format in the sense that Windows uses the term. It is not really a traditional container format either since there is no universal tool that will read it, unlike zip for example. It is a database structure like the name says. (PDB stands for Palm DataBase)
The Palm OS does not have files in ram at all. When the data is backed up to a pc then the extension is added to identify this is being stored on a pc as a Palm type of file but does not identify the tool needed to read it. That data is done like a Mac as a resource and it is embedded a few bytes into the file itself. Check the wiki for more details on pdb, prc, PalmDOC and other reader formats that can exist on Palm devices.
