XS_AUTOSAVE_DIRECTORY
Category in Advanced options dialog box: File locations
Use this advanced option to define the path to the folder that contains the files that Tekla Structures saves automatically. The default value is %XS_RUNPATH%\autosave\.
If you do not define a path, Tekla Structures places autosave files in the current model folder.
This advanced option is user specific and the setting is saved in options.bin under the user folder, for example, in C:\Users\<user>\AppData\Local\Trimble\Tekla Structures\<version>\UserSettings. Restart Tekla Structures to activate the new value.
