ParaView/Users Guide/Loading Data
Loading data is a fundamental operation in using ParaView for visualization. As you would expect, the Open option from the File menu and the the Open Button from the toolbar both allow you to load data into ParaView. The list of supported file formats for ParaView can be found on the List Of Readers. Because of ParaView's modular design it is easy to integrate new VTK readers so check beck every release for new supported file formats. If you are interested in creating new readers for ParaView see the HowTo

Another option is to load a previously saved state file (File menu, Load State). This will return ParaView to its state at the time the file was saved by loading data files, applying filters.
Advanced Data Loading
If you commonly load the same data into ParaView each time, you can streamline the process by launching ParaView with the data command-line argument (
--data=data_file). You can also launch ParaView
Note that opening a file is a two step process, so that you do not see any data after opening a data file. Instead, you see that the object inspector is populated with several options about how we want to read the data.
Once you have enabled all the options on the data that you are interested in click the Apply button to finish loading the data.
