Once in
PARTproject or on
file level, new directories are created, in PARTadmin, in the index
administration, the respective icon
is displayed.
The command is displayed when calling the context menu on the respective directory.
As an alternative - as long as no index exists - you can delete the data again (in PARTproject or on file level).
When executing this command, the clicked directory including all subdirectories is searched and the Display index is updated.
The display index is needed for saving or display of the directory structure. It has to be available in order for catalogs to be displayed in PARTdataManager. Other indices are optional for PARTdataManager functionality (however, useful in order to be able to use both Full-text search and the different geometrical search methods).
once the command has been executed, in the display area below, under Index update, the progress is shown.
Display index -> Add missing directories to the display index
The function only adds missing directories into the index, which are directly under the chosen one. Directories, which are further down in the hierarchy are not added.
