.PMLZ File Extension

Many Palm PDAs included an app known as eReader or Palm Reader. This app allowed users to read eBooks saved in the PDB format.

To create a PDB file, eBook publishers created one or more PML files, which defined the eBook's content and formatting. Optionally, users could zip several PML files together into a PMLZ file, and then use that file to create their PDB eBook.

You can use any Zip-decompression utility, such as 7-Zip, The Unarchiver, or B1 Free Archiver, to extract the PML files a PMLZ file contains. In some cases, you may have to first change your file's extension from .pmlz to .zip.
