Since version 7 LabChart enables you to create an ADInstruments custom file format (.adipak) with Windows Explorer integration, allowing for easy installation of content into the Gallery of the LabChart Welcome Center.
Although it seems to create an archive similar to winzip.exe, it only works when right-clicking on a folder, not on a selection of files. Please compare the difference when right-click a selection of files or a folder in the image below. Only the latter one will allow to create a LabChart Package. For further information regarding LabChart packages please refer to the LabChart help under Welcome Center > Gallery > LabChart Packages.
