  - no association.
  - AppName - the extension is associated with another program (not 7-Zip).
  - [7-Zip] - the extension is associated with another copy (edition) of 7-Zip.
  - 7-Zip - the extension is associated with this copy of 7-Zip.

  You can switch between these states by clicking on cell. Or you can change states for all extension by clicking on "+" button.

## 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. There are two check boxes in 64-bit system. So it's possible to enable 7-Zip context menu for 32-bit and 64-bit applications.
Cascaded context menu
  Select this check box to group 7-Zip context menu items to one 7-Zip submenu.
Icons in context menu
  Select this check box to show 7-Zip icon in context menu items.
Eliminate duplication of root folder
  That option allows to eliminate duplication of root folder for "Extract to" operations, if all files in archive are placed in folder with name that is identical to name of output folder.
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.

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.
