File Open dialog

Used to open an existing DGN file or a file of a different type as the active DGN file.

You can access this dialog from the following:

Work page: Browse
Ribbon: File > Open > Browse

Controls on these two dialogs are analogous but only the File Open dialog allows you to select or change the WorkSpace or WorkSet .

If you prefer to use the MicroStation Manager-type File Open dialog, from the Preferences dialog File > Settings > User > Preferences Look and Feel category, turn off Use Windows file open.

A thumbnail image is stored in each DGN file that can be seen in the File Open dialogs as well as Windows Explorer (the latter in versions of Windows that support this functionality). After you have opened the file in a design session and selected File > Save Settings once, the thumbnail image is saved as a bitmap in standard clipboard format.

The MS_THUMBNAIL configuration variable can be used to control the behavior of thumbnail generation.

Key-in: DIALOG OPENFILE Key-in: EXCHANGEFILE <file_name>

Note: By default, File Protection encrypts a file's thumbnail image and summary properties. These are the items displayed in Windows File Explorer, File Open, and File Properties dialogs. To remove encryption, you must set the MS_PROTECTION_NOENCRYPT_THUMBNAIL and/or MS_PROTECTION_NOENCRYPT_PROPERTIES configuration variables.

Note: Using the NEWFILE (RD=) key-in can be faster than using the Open dialog to open a design file. The syntax is RD=<design_file> or NEWFILE <design_file>.

Note: You can open a DGN file with the view configuration of the active design file by keying in EXCHANGEFILE <filename>.

Setting	Description
File	A drop-down list which consists of recently opened files and the following option: Compress File - Reduces the size of the open DGN file by purging empty and unused data resources. Note: If Use Windows file open is off, this control is accessed from File > Compress Design.
Directory	A drop-down list which consists of recently accessed directories and following directory option: Select Configuration Variable - Opens the Select Configuration Variable dialog. Use this dialog to change the directory of files listed in the list box by selecting a configuration variable whose definition points to a different directory. List box ? Lists path and directory configuration variables for selection. Text box ? When a configuration variable is selected, the directory in its definition appears here. OK ? Accepts the selected configuration variable and closes the dialog.
