.PMP
é um formato de propriedade do Picasa, usado para armazenar informações sobre imagens.

(Nota: a postagem do blog abaixo referenciada é datada, não tenho certeza da relevância / correção dela para a versão atual do Picasa)
in the db2 directory there are a number of files. The important files for this are
albumdata_token.pmp
,albumdata_uid.pmp
andalbumdata_name.pmp
Here are the contents of the files:
albumdata_name.pmp
-this is the name of the albums in picasa. The first two are defaults and are not included in any of the other files.
Starred Photos
Screensaver
root
modified_for_tags
sam3
Sample Pictures

albumdata_uid.pmp
- This is where the hashes are.

albumdata_token.pmp
Here's we see the uid applied to create a token for the albums. Note that "star" and "screensaver" do not have uids.
]star
]screensaver
]album:b131d7e17dfdff73eb0340b4e9d3d6f3
]album:8e92a45a6abed421488a5774ec3f4a4c
]album:ca05c73419475ade037f8df528849c91
]album:ec9771e026e3ce55c468354abcfce4ee
]album:c332f1814ff6d4f21dbb41b41149544d
Now, if we look at the
lastalbumselected
value in the registry, we can pair it up to the hash since these files are all listed in the same order. If you excludestar
andscreensaver
you can see that thelastalbumselected
for me wassam3
.You can even go one step further if you include albumdata_filename.pmp. This file also matches up to the other files, except I forgot to mention one thing. "root" is literally the root of the logical drive that picasa searched(in this case C:), so it is excluded from
albumdata_filename.pmp
. This file contains the path to where the images are stored.Other files to pay attention to:
bigthumbs.db
thumbs2.db
thumbs.db
previews.db
These all follow the good old
thumbs.db
structure and contain thumbnails of all of the images at various resolutions, since picasa can send files directly to photo processing businesses.One other thing that is of pretty vital importance in terms of proving that someone created an album and that the program didn't just index something.
In the
Picasa2Albums
directory you'll see a file for each of the album(s) created by the user under the folder using the DBID as its name. Below are the contents of the album I created stored in a file named {c332f1814ff6d4f21dbb41b41149544d.pal.
