3.7.4 Tool Sets
Acrobat 11.0 introduces a streamlined way to create and manage custom tool sets across the enterprise. A Customize button in the upper right-hand area of the toolbar allows users to create new tool sets, manage existing tool sets, and choose any existing tool set.
This feature helps organizations standardize task-specific tool views, reduce training costs, and improve employee efficiency by grouping related tools into a common view. This feature allows:
End users to easily create or import custom tool sets.
Easy switching between different tool sets.
IT to create, distribute, and otherwise manage tool sets across the enterprise.

3.7.4.1 Tool set file locations
Tool set files reside in two locations:
A local user directory (full access): Files which are stored and imported by the current user are placed in the default current user’s directory. For example:
C:\Users\<username>\AppData\Roaming\Adobe\Acrobat\11.0\UICustomization\<anyname>.aaui
A local, product directory (read only): Files in this directory are visible to any user on the machine. For example:
C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\UICustomization\<language>\<anyname>.aaui
