Palm Database of PalmDoc eBooks (.pdb)
The PDB (Palm Database) file extension, associated with PalmDoc eBooks, is a format used for storing eBooks on Palm OS devices. Originating from AportisDoc, PalmDoc files are plain ASCII text compressed using Run-Length Encoding (RLE) to save memory space. These files are decompressed on the fly by PalmDoc readers, facilitating efficient storage and quick access. The PDB format, with its Creator ID and Type attributes, ensures compatibility across various Palm applications, making it a versatile choice for eBook distribution on Palm devices.
