XS_KEEP_AUTOSAVE_FILES_ON_EXIT_WHEN_NOT_SAVING
Category in Advanced options dialog: Modeling properties
When you close a model, Tekla Structures deletes autosave files to save disk space. If this advanced
option is set to TRUE, Tekla Structures does not delete these files, even if you
exit Tekla Structures without saving the model. To delete the autosave files when you close a
model, set this advanced option to FALSE. The default value is TRUE.
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.
