Base Source Directories are defined when you create a User Workspace (V8i) or User Workset (CONNECT Edition). For new workspaces and worksets, this is defined by the variable %BaseSourceDir% which is hard coded to the following folders:
V8i - ...\Workspace\Projects\Examples\Geospatial\defaults
CONNECT Edition - ...\Configuration\WorkSpaces\MapDefaults
When Tools > Expand Variables is turned OFF, then the following will display when you create a new workspace/workset:
As well, this variable will be written to the XML file as noted in a text editor:
When Tools > Expand Variables is turned ON, the following occurs by default:
NOTE: Turning Expand Variables on or off may require you to reopen the schema to take effect.
NOTE: When working with existing projects that were saved with the Expand Variables OFF, you can write the full path to the XML file by doing a Save As to a new file. Likewise, when working with existing projects that were saved with Expand Variables ON, you can change the full path in the XML to read %BaseSourceDir% by doing Save As to a new file.
To override the default location of %BaseSourceDir%, append the following command line option to the Target field of your icon.
-bsd=Your source file location
New worksets will use the location defined by this command line option:
