Double clicking on a file will cause it to be opened in a jEdit buffer. If the file is already open, then ProjectViewer follows the FileSystemBrowser configuration option to decide whether to close it or not.

Middle-clicking on a file does the same as double-clicking, except it will always close open files.

The right mouse button shows a context menu with options related to the current selection on the tree, allowing you to remove files or directories from a project, deleting them from the disk, or rename them, among many other options.

Dragging a file from the trees and dropping it on jEdit's text area will cause the file to be opened.

Traverse directories: if a directory is chosen to be imported, this option will cause all files and directories under the chosen directories to also be imported, as long as they fit the chosen filter.

Flatten file paths: when traversing directories, you may choose to import all the files into a single node, insted of generating a directory tree.

Keep Project Tree: if you choose to import files several leves under the chosen node, this option will make all parent nodes be added to the project too, making the project's layout follow the filesystem layout. This is selected by default.

Import into new node: this will create a new node under which you are importing files, and all newly added files and directories will be placed under this new node.

Filter settings: when traversing directories, you may choose from some existing file filters to choose the files to be imported, or create your custom file filter on the fly by providing globs for files to be included and directories to be ignored. For more information about the glob syntax, see "Import Options" under the "Customization" chapter.

Add files: pops a file chooser from where you can choose any files or directories to import. These will be imported into the selected node, disregarding the file system layout. If importing directories, you'll be prompted if you want to do it recursively using one of the available filters.

Add files from VFS: lets you select files from a jEdit VFS (Virtual File System), such as FTP. If you choose local files, ProjectViewer will add standard files instead of VFS files. The functionality of VFS files in ProjectViewer is rather limited when compared to standard files.

Re-import files: this command will remove all files and directories below the project root, and re-read the file structure from disk according to the selected filter (which can be chosen from the dialog that pops up). It will also analyze directories not under the project root: it will re-import existing directories and remove stale files from "virtual" directories.

Update VCS Status: this command is available only if the project has specified a version control system. This command forces an update of the version control status for every file in the project. This is useful for projects that may have files that are updated outside of jEdit.

Remove from project: this will remove the selected node from the project to which it belongs. It is also possible to remove multiple nodes at once.

Delete from disk: this is only shown for files to which you have write permission. Choosing it will cause the files to be deleted from disk and removed from the project.

Rename: this will prompt you for a new name for the selected node. If you check the "Don't change name on disk" option, only the node name on the tree will be changed; the file on disk will keep its current name.

Archive project: this will prompt you for a file name. A JAR archive will be created containing all files below the project root.

Preview in browser: this will open the file in the configured web browser. If a project URL is set, files below the project root will be redirected to the given URL; in other cases, the "file://" protocol will be used. The part of the file path corresponding to the project root will be removed when opening the file relatively to the project URL.

Open with: this will open the selected file in a configured application associated with its extension (configured in the Project Viewer's plugin options). If no application is configured for the selected file, selecting this option will prompt you to choose an application.

Node Properties: this shows a dialog with information about the selected node. For example, for file nodes, you can get information collected from the filesystem.

Use external applications by default: if selected, files that are open from the tree (by either double-clicking or middle-clicking) will be opened using the external application configured for the file's extension, if any. If no application is found, it will be opened in jEdit. You can still open the file in jEdit by dragging the file node onto jEdit's text area. When opening in an external application, you'll lose support for auto-closing the file on project file, auto-loading the file when the project is re-activated and the file node won't be underlined, indicating it is opened..

Close files on project change: if selected, files from the current project that are opened in jEdit will be closed when you switch to another project.

Remember open files: if selected, files opened in the current project will be re-opened when you select the same project in a later moment, even between different jEdit sessions.

Use variable-prefixed paths when storing project data: If selected, will use paths prefixed with environment variables, if appropriate variables are found in memory. This makes it possible to move project data from one machine to another when the absolute paths differ, but the paths relative to a variable remain the same.

Auto-remove non-existant files from project: if selected, each file in the project is verified to exist when the project loads. If the file does not exist, it is removed from the project.

Ask to import new files: if "Always" is selected, every time you save a file located below the active project's root, and the file is not yet part of the project, you'll be asked whether you want to import it. Selecting "Once per session" will ask only one time during the time the current project stays active. "Never" will disable this feature. "Auto import" will automatically add to the project any saved files which are under the project root and are not currently part of the project.

Show toolbar: whether to show the plugin's toolbar or not. The toolbar is automatically hidden when no tree is selected for showing, regardless of this option.

Show folders tree: if the "Folders" tree view should be shown.

Show files tree: if the "Files" tree view should be shown. Disabling this view can greatly improve performance when your projects have many files.

Show working files tree: if the "Working Files" tree view should be shown.

Show all open files: if the "Working Files" tree is shown, checking this will also show all open files in the current View, whether the files are in the project or not.

Show compact tree: whether the "Compact" tree view should be shown.

Show filtered tree: whether the "Filtered" tree view should be shown.

Use system icons for files: instead of using jEdit's icons, uses the system provided icon for each individual files. The jEdit icon will still be used when the file is opened. On some systems, the system icons may not be accessible from Java, so this option may not work as expected.

Show project (or group) name in the view's title bar: if selected, the jEdit window title will be updated with information about the currently active project or group in that window.

Follow active node in tree: this option will make PV automatically select the node corresponding to the active buffer as you switch between buffers.

Files to include: a list of globs that match files you want to include in a project (e.g., "*.html", "*.java", "README*"). If you want to exclude files from the automatic import, prepend the glob with the "!" character (e.g., "!*.class").

Directories to ignore: space-separated list of globs to match directory names to ignore when doing automatic import of files. No files within directories whose names are listed here will be imported.
