# Options Dialog Box

You can change many of the settings that affect the 7-Zip File Manager in the Options dialog box. To access this dialog box select Options from the Tools menu.

The options dialog box contains the following pages:

- System Page
- 7-Zip
- Folders Page
- Editor Page
- Settings Page
- Language Page

## System Page

Allows you to specify the behavior of 7-Zip in the filing system.

Associate 7-Zip with
  Lists the file name extensions and associated plugins that are currently registered with 7-Zip. If file name extension is checked, 7-Zip will be used to open file with that extension. In any case you can always open all archives with 7-Zip via your right-click context menu.

## 7-Zip Page

Allows you to specify behavior of 7-Zip in Windows Shell.

Integrate 7-Zip to shell context menu
  Select this check box to add 7-Zip commands to Shell Context Menu.
Cascaded context menu
  Select this check box to group 7-Zip context menu items to one 7-Zip submenu.
Context menu items
  Lists the optional context menu items. If an item is checked, 7-Zip will add this item to the context menu.

## Folders Page

Allows you to set the folders which 7-Zip will use for internal purposes.

### Working folder

The working folder section allows you to specify a folder which will be used for temporary archive files:

System temp folder
  7-Zip will use the Windows temp folder.
Current
  7-Zip will use the folder containing the target archive.
Specified
  7-Zip will use the folder specified in the following edit control.

Use for removable drives only
  Specifies whether 7-Zip should use the specified folder settings only for removable drives; for other drives, 7-Zip will create temporary archives in the folder containing the target archive. If you clear this check box, 7-Zip always will use the specified folder settings mode always.

7-Zip uses temporary archive files for all update operations. So, for speed reasons, it is recommended that you select the System temp folder option and select Use for removable drives only check box.

## Editor Page

Allows you to specify settings for the editor.

View
  Specifies the path to the viewer that will be used for "View" command (F3).
Editor
  Specifies the path to the editor that will be used for "Edit" command (F4).
Diff
  Specifies the path to a file comparison utility that shows the differences between two files.

## Settings Page

Allows you to specify some settings.

Show .. item
  Shows .. item in file list.
Show real file icons
  Shows real file icons in file list. If this option is enabled, listing updates can be slower.
Show system menu
  Shows a system context sub-menu in the File menu.
Full row select
  When an item is selected, the item and all its subitems are highlighted.
Show grid lines
  Displays gridlines around items and subitems.
Single-click to open an item
  If enabled, File Manager opens files and folders by single-clicking them.
Alternative selection mode
  If enabled, File Manager keeps selection mark when you move cursor.
Use large memory pages
  If enabled, 7-Zip will try to use large pages. This feature allows an increase in speed of compression. This may cause 7-Zip to pause when starting compression, because of allocation of the large pages. Also, the Windows Task Manager doesn't show the real memory usage of the program, if 7-Zip uses large pages. This feature works only on Windows 2003 / XP x64. Also you must have administrator's rights for your system. Recommended size of RAM: 1 GB or more. To install this feature you must run 7-Zip File Manager at least once, close it and reboot the system.

## Language Page

Allows you to change the default language.

Language
  Lists the available languages.
