Update (13/05/2014): A free demo version of this script is now available! This version works just like the full version, but it allows you to create only 1 session with up to 3 files in it. The full version has no limitations on the number of sessions or files.

Many applications offer the option to save your current workspace as a session and to restore it later. Let's say you're working on a project and have multiple documents open and you want to move to a different project, or just need to close the application. You save your workspace and later on you restore it and continue working from the spot you've left it off.

Unfortunately, Acrobat does not offer this functionality, until you install this script...

With this tool you can maintain an unlimited amount of sessions, which will remain even when the application is closed or the computer is restarted. The session contains all of the currently opened files, and the exact location where you left them off.

The tool adds a new "Sessions" menu under the "Window" menu:

When creating a new session, you give it a name:

And then you can load it later on:

You can also list all of the sessions currently available (and their associated files):

This tool is also compatible with Adobe Reader!
