+====== File Open ======
+===== Overview =====
+The **File_Open** pipeline command is used to load a file into the Visual3D workspace.
+  * Usually, this command is the first step in a pipeline as all subsequent operations rely on having an active file loaded.
+  * For supported files and filter types, see the notes section.
+===== Pipeline Command =====
+The command below is as seen in the Visual3D application.
+<code>
+File_Open
+! /FILE_NAME=
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+;
+</code>
+===== Command Parameters =====
+The following table shows the command parameters:
+|**Parameter**               |**Description** |
+|**/FILE_NAME=**             |Name of the file being opened. This can be left blank if prompting the user|
+|**/FILE_PATH=**             |Path to the folder where the file is stored.|
+|**/SEARCH_SUBFOLDERS=FALSE**| If set to 'TRUE', Visual3D will also search in subfolders under 'FILE_PATH'|
+|**/SUFFIX=**                |Optional suffix to append to the base file name.|
+|**/SET_PROMPT=File_Open**   |If provided, prompts the user with a dialog box titled with this label to choose a file manually.|
+|**/ON_FILE_NOT_FOUND=PROMPT**|If the file is not found, 'PROMPT' or 'SKIP'|
+|**/FILE_TYPES_ON_PROMPT**    |Filter for the file types when using prompt.|
+===== Dialog Box =====
+The command can be edited in a text editor or in a dialog form. To edit in the dialog, either click on the **Edit** button in the pipeline workshop or double-click on the pipeline command.
+The dialog is shown below:
+{{:visual3d:documentation:pipeline:file_commands:file_open_emptydlgbox.png?550|}}
+  * **Select Filename**: Manually browse for and select the specific file you want to open.
+  * **Select Filepath (Optional)**: Choose the folder where the file is stored.
+  * **Suffix**: If a file with this suffix exists in the folder, it will be automatically added to the file name.
+  * **Search Subfolders**: If checked, Visual3D will search within subfolders of the specified file path to find the file.
+  * **Prompt**: Sets the title shown in the file selection dialog when prompting the user to choose a file.
+  * **Action on File Not Found**: What Visual3D should do if the file is not found. Options include PROMPT or SKIP
+  * **File Mask on Prompt**: A filter for which file types appear in the dialog.
+===== Examples =====
+The following examples will go through the use of the **File_Open** command within the Visual3D application.
+=== Example 1: Prompt the user for the filename ===
+This example will prompt the user for the files by opening a dialog box for selection.
+<code>
+File_Open
+/FILE_NAME=
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+;
+</code>
+=== Example 2: Specify the filename ===
+This example specifies the filename explicitly. Note that the filename should contain the complete path to the file.
+<code>
+File_Open
+/FILE_NAME= c:\demo_files\walking.c3d
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+;
+</code>
+=== Example 3: Specify the filename using wildcards ===
+This example specifies the filename by using a wildcard. All C3D files in the c:\demo_files folder will be opened.
+<code>
+File_Open
+/FILE_NAME= c:\demo_files\*.c3d
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+</code>
+=== Example 4: Specify the filename using a pipeline parameter and wildcards ===
+This example uses [[Visual3D:Documentation:Pipeline:General_Information:Pipeline_Parameters|Pipeline Parameters]] to specify the folder containing the data files and uses a wildcard in the filename
+<code>
+Set_Pipeline_Parameter_To_Folder_Path
+/PARAMETER_NAME= DATA_FOLDER
+/PARAMETER_VALUE=c:\demo_files
+;
+! Now open the file.
+File_Open
+/FILE_NAME= ::DATA_FOLDER&*.c3d
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+</code>
+=== Example 5: Specify the filename using the default data folder and wildcards ===
+This example uses [[Visual3D:Documentation:Pipeline:General_Information:Pipeline_Parameters|Pipeline Parameters]] to specify the [[Visual3D:Documentation:Dialogs:Program_Options#Default_Folders|default data folder]] containing the data files and uses a wildcard in the filename.
+<code>
+Set_Pipeline_Parameter_To_Folder_Path
+/PARAMETER_NAME= DATA_FOLDER
+/PARAMETER_VALUE=VISUAL3D_DEFAULT_DATA_FOLDER
+;
+! Now open the file.
+File_Open=
+File_Open
+/FILE_NAME= ::DATA_FOLDER&*.c3d
+! /FILE_PATH=
+! /SEARCH_SUBFOLDERS=FALSE
+! /SUFFIX=
+! /SET_PROMPT=File_Open
+! /ON_FILE_NOT_FOUND=PROMPT
+! /FILE_TYPES_ON_PROMPT=
+</code>
+===== Notes =====

+The following file types are supported and can be added within Visual3D:
+  * .c3d - C3D File or [[http://www.c3d.org|www.c3d.org]]
+  * .cmz - Visual3D Workspace File
+  * .h5 - Visual3D [[..:..:definitions:file_formats:hdf5|HDF5]] Workspace File
+  * .txt - Visual3D TAB delimited text File
+  * .gcd - Vicon GCD File
+  * .ndi - NDI Aurora File
+  * .p2d - P2D File
+==== File Search Filter Types ====
+You can filter using the following filter types:
+  * C3D
+  * CMZ
+  * HDF5
+  * VND
+  * P2D
