User preferences are stored in the file structure101.cpp.ini, located in the (platform-specific) "user" directory. On Windows, this is usually C:\Documents and Settings\<username>\Structure101\cpp.

To use a different directory, provide a file "paths.ini" in the installation directory with an entry in the following form:

options-dir=<path>

(Note: paths.ini is included automatically for Mac OSX distributions and points to Library/Structure101 Studio for Cpp)

Most preferences (e.g. window and splitter locations, recent files and repositories, option settings, etc.) are inferred directly from the UI.

A very small number of settings can only be changed by directly editing the preferences file. One such example is the thresholds for displaying graphs (if the value for a particular graph is bigger than the relevant threshold, you will see a "This graph is too big to display" message). To change the defaults, look for the following section in the preferences file and edit as appropriate.

[graph-thresholds]
max-diagram-edges-partitioned=500
max-diagram-edges-unpartitioned=300
max-model-nodes=2400
use-custom-graph-sizing=true

To ensure custom settings are used, the use-custom-graph-sizing must be true. If not, then settings determined by the application will be used.

To reset all preferences to defaults, just delete the preferences file.
