Preferences

You can configure many aspects of Notepad++ using the Preferences dialog. The dialog consists of multiple tab which contain options that are relevant to some aspect of Notepad++ (for instance, the interface or backup options).

General

The general settings control the look of the main interface. You can control the Tab Bar, the Tool Bar, the Status Bar and the menu from here, as well as the current ...

Localization:

This dropdown list shows all the languages which you can use for Notepad++ to speak your language. If you click on one of these languages, all user interface elements are instantly translated into that language. The various localisation files are in the Localization subfolder of Notepad++'s install folder.

Tool bar:

Hide - Check the hide checkbox to completely hide the tool bar. The following choices show immediate results, but sometimes a restart is required to load the correct icons:
Small icons - Notepad++ will use the small icon set for the toolbar. This can be the built-in icon set or custom icons.
Big icons - Notepad++ will use the large icon set for the toolbar. This can be the built-in icon set or custom icons.
Small standard icons - These are the default built-in icons. This is also the only option that will show any tool bar icons registered by plugins.

Menu bar:

Hide - If you check this option, the menu bar will automatically hide. To (temporarily) show the menu bar, press the Alt key or the F10 key to give the menu focus. Selecting an option, pressing escape or giving another window the focus will hide the menu again.

Status bar:

Show status bar - Check the option to show the status bar.

Tab bar: Hide - Checking this option will hide the tab bar. You can still open multiple documents but you have to switch using shortcuts rather that using the tab bar. Multi-Line - Checking this option will cause the tab bar to draw multiple rows of documents if they cannot all be displayed in a single row. Otherwise a pair of scroll arrow buttons will appear. Note that the active document will always be on the bottom row. Vertical - Checking this option will rotate the tab bar 90° counterclockwise and place it at the left side of the screen. Reduce - If checked the tab bar will use the default font and icon size. Unchecking will cause it to use a larger font and larger icons. Lock - Checking this will disable the ability to sort documents by dragging the tabs around. Draw the inactive tabs - If checked, inactive tabs will be drawn using a custom background color (see Settings, Styler Configurator). Draw the orange top bar - Checking this will draw a (by default) orange line on top of active tabs (see Settings, Styler Configurator). Enable close button on each tab - Checking this will add a close button on each tab. Clicking it will close that tab. Double click to close document - If checked, doubleclicking on a tab will close it.

Editing

These settings affect the behaviour and look of Scintilla, the edit component of Notepad++.

Caret settings

The following options are changed per view (See Multi View). Select the view to adjust form the combo box.

Folder margin style

New Document/Open Save directory

These options change the way new documents are created and what the default Open/Save directories will be.

New document: Encoding: Allows to choose what encoding to use (see Encoding). Format: Allows to choose what end-of-line format to use (see Newline Format). Default language: defines which highlighter will be used for any newly created document. The dropdown list mirrors the Language menu. However, user defined languages and external languages cannot be selected.

File Open/Save Directory:

The File Open/Save Directory, or Default Directory, controls what directory Notepad++ looks in when opening or saving files. Please note that the Default directory is not the same as the Current Directory (Working Directory) Notepad++ uses. Do not make assumptions about Notepad++ Current Directory.

Follow the current document - If this option is selected, the default directory will be the directory of the currently active file. If the file is a new, unsaved document, this will be Notepad++' directory.
Remember the last operation directory - If this option is selected, the default directory will initially be the directory Notepad++ was started in (you can control this by adjusting the shortcut you use for Notepad++) and only change when browsing for files (to open or save a file).
Custom - The default directory can be set to a fixed path. Browse for a path or type it yourself. If the path is invalid, Notepad++' directory will be used. You are allowed to use Environment Variables, using the $(var-name) syntax as usual.

File Association

You can associate files with Notepad++ so opening those files will start Notepad++. Select a type of file, then select the desired extension and press the left arrow to associate the file. To add a custom type of file, select customize, enter the extension and press the -> button. To remove the association, select the extension to dissociate and press the arrow next to the garbage can.

Language Menu/Tab settings

You can select the languages that are available from the Language menu. In the Available Items list are the languages that are currently visible. To hide a language form the menu, select it and press the -> button to put it in the Disabled Items list. Add the language again by selecting it from the Disabled Items list and pressing the <- button.
The appearance of the Language menu can be further controlled by the Make Language menu Compact checkbox. When checked, languages whose names start by the same letter are grouped into a submenu, rather than being all lumped in the menu proper.

Tab settings can be adjusted on a per language basis. The right hand list has all built-in languages, as well as a topmost (Default) entry. The latter applies to all languages which don't have a custom setting, as well as to all user defined languages. The frame below allows adjusting tab settings for the selected language:

Tab size - Size in space characters of a tab character in the document.
Replace by space - Checking this will cause any tabs added to be in the form of spaces, up to the amount as determined by the Tab size setting.

Print

Use these settings to adjust the layout and colors used when printing a document, as well as the page header and footer text. This can be any regular string or a variable that will change depending on the printed document.

Print line number - If selected, linenumbers will be printed aswell.
Colour Option:
- WYSIWYG - print colours exactly as they are on the screen.
- Invert - This will print the document with the background color inverted (white becomes black for instance, and v.v.) and the default foreground color inverted. All other colors will remain the same.
- Black on white - All text will be printed black and a white background.
- No background color - This will print all the text colored, but any background colors (including the default color) will be printed white.

Variables: You can use Variable: variable text inside the current header/footer. There are a few default variables listed, but you can also use any variable used by the Run dialog (see Commands) as well. The syntax is the same. To add some predefined variable from the dropdown, click Add. The name will automatically be escaped.
Header:: Control the header text. If any header text is present, it will be separated from the document with a line. Use the various edit controls to adjust the text added to the header. You can add text in the left aligned, right aligned and centered sections. The controls below control the font used by the header.
Footer:: Control the footer text. See Header for more information.

Backup/Auto-Completion

Backup:

Control backup behaviour. You can instruct Notepad++ to automatically make a backup of every file if you save any modifications.

None - No backups are made.
Simple backup - A backup is saved to a file with the same name and .bak added as extension (the original extension is preserved).
Verbose backup - Like simple backup, but before the .bak extension a short date and timestamp is added.
User custom backup directory - If checked, a custom backup directory is used instead of saving to the same directory the file resides in. If the path is invalid the directory the file resides in will be used.

Auto-completion:

See Auto-Completion on what Auto Completion is.

Enable Auto-completion on each input - If checked, Notepad++ will try to autocomplete the current word being typed based on how much is already written.

Function Completion : try to complete the current word using the list of functions of the current language.
Word completion : try to complete the current word using the words in the document.
From #th characters: Enter amount of characters needed before Notepad++ tries to auto-complete the current words. Allowed values range from 1 to 9.

Function parameters hint on input - If checked, when a character is added that marks the start of a list of arguments of the currently typed function, the function parameters calltip will be shown.

MISC

These settings control other aspects of Notepad++.

History File Setting: Max number of history file # - Any number from 0 up to 30. Controls the amount of files that are saved in the history. Don't check at launch time - If checked, Notepad++ will not verify the validity of the files in the history. If unchecked, Notepad++ will check the existence of each file. Recommended to be turned on in case of networked files.

Document switcher: (See Document Switcher) Enable - Enable the document switcher. Enable MRU behavior - Enables the MRU style sort of files in the document switcher.

Clickable link settings:

This feature optionally makes web addresses starting with http:// clickable. Double clicking opens that address in your browser, if any is installed and registered.

Enable - If enabled, http:// addresses are clickable as soon as they have been typed and caret leaves them.
Don't draw underline - If enabled, the address will be drawn without an underline. Underlining is the default.

File Status Auto-detection:

Automatically checks the status of each opened file when Notepad++ is activated from the background.

Enable - Check to enable status detection.
Update silently - If a change to a file is detected (modified contents), Notepad++ will reload the file without asking.
Scroll to the last line after update - If checked, when a file is reloaded after an external modification is detected, it will be scrolled to the last line (useful for tailing log files).

Highlight matching tags:

Tag highlighting is used for HTML/XML languages. When the cursor is located inside or at a tag, corresponding tag entries will be colorized. Change the colors using the Styler Configurator.

Enable - Check to enable tag highlighting.
Highlight tag attributes - If checked, the attributes of a tag will be colorized as well.
Highlight comment/php/asp zone - If checked, tags inside a php/asp zone will be matched as well.

Sessions Remember the current session for next launch - If checked, the all the files opened in Notepad++ will be opened again if Notepad++ is closed. If an extension is entered in Session file ext, Notepad++ will try to open these files as session files instead of regular files. This allows you to simply provide a session file via the command line or any other method of opening a file to load a session into Notepad++.

Other options Enable Notepad++ auto-updater: If checked, Notepad++ will attempt to find about an update at startup. You have the option of postponing the upgrade if one is found. Auto-indent - If checked, adding a new line will automatically indent that line if any line with text before it has indentation as well. The indentation will then be matched. Minimize to sys tray - If checked, minimizing Notepad++ will cause it to be hidden from the taskbar and an icon to be added to the system tray (notification area). Clicking the icon will bring Notepad++ back to the foreground. Smart highlighting - If checked, any word that matches the currently selected word in the screen will be highlighted. You can control the color using the Styler Configurator. Show only filename in titlebar - If checked, instead of the full path to the active file only the filename will be displayed.
