Open/save dialogs are used for most file opening and saving operations within Chimera. Several features are common to all open/save dialogs, including how directories are shown and navigated. A given dialog may include additional features, depending on the function or tool from which it is called and whether opening or saving is being performed.
The Chimera Open File dialog is invoked by choosing File... Open from the menu. Any of the registered file types can be opened from this dialog.

Certain buttons are common to most open/save dialogs. Open or Save performs the indicated operation and dismisses the dialog (although there is a checkbox option to Keep dialog up after Open). Close dismisses the dialog without performing the operation. The Help button brings up a manual page in a browser window.

Open/save file browser dialogs start in the location of the most recent of:
In some situations, loading all of the levels in the directory hierarchy can be slow. The size of open/save dialogs can be limited to the two lowest levels by setting Use short open/save browser to true in the General preferences. With this setting, open/save dialogs will contain only the two lowest levels when:
On Windows, shared file systems in the network neighborhood cannot be browsed to directly, but can be accessed by entering
\\hostname\share_folder_namein the Folder field. This enables browsing within the share folder hierarchy. Similarly, a full pathname can be entered in the File name field, for example:
More than one file can be opened at a time. After navigation to the desired directory, individual filenames or blocks of filenames can be chosen with the left mouse button. Ctrl-click adds to an existing choice rather than replacing it. To highlight a block of filenames without having to hold down the mouse button, click on the first (or last) and then Shift-click on the last (or first) in the desired block.
Only the files with suffixes appropriate for the File type setting will be listed. In many cases, compressed files (*.gz, *.Z) of those types will also be listed and can be opened. The possible File type settings vary depending on the specific dialog. Any of the registered file types can be opened from the Chimera Open File Dialog; if the File type is all (ask type) or all (guess type), all files will be listed. If a tool-specific file type is opened, the associated tool will be executed or started, if it has not been started already.
Prefixes cannot be used, and there is no default file type. If a file is one of the registered types but is not named with the correct suffix, it can be read by either (A) setting the File type accordingly and entering the filename manually, or (B) changing the File type to all (ask type), clicking on the filename or entering it manually, and then indicating the file type when queried.
The names of recently opened files are available from a pulldown menu to the right of the File name field (marked with a black triangle). When a file is opened, the file pathname is added to the recent file list. The recent file list and the most recent File type setting for each open dialog are stored in the preferences file.
Open opens the indicated file(s) and dismisses the dialog unless Keep dialog up after Open is checked.
After navigation to the desired directory, the name of the file to be saved should be entered in the File name field (or chosen with the left mouse button, if a file of the same name already exists). The file types and contents that can be saved depend on the function or tool from which the dialog is called. A save dialog may include a checkbox option to Add .xyz suffix if none given, where .xyz is the default suffix for the given File type. When the option is on, a suffix will be added only to a filename lacking a suffix; when the option is off, suffixes will not be added automatically.

Save saves the indicated file and dismisses the dialog.
