Adding Items
To remove an item select it in the file type listing and then press the "Remove" button, select "Remove" from the "Actions" menu or right-click on the file type listing and select "Remove" from the popup menu. This will cause File Type Manager to ask you if you really want to remove the item.
Note that some items can not be removed, in that case the "Remove" option will be disabled.
Removing items can have unintended consequences and you should be careful when removing certain items. Special considerations are listed below.
File Types
The image below shows the "Remove" dialog when removing a file type:

Special considerations:
- Removing a file type will also remove all file extensions, actions and shell extensions of that file type.
File Extensions
The image below shows the "Remove" dialog when removing a file extension:

Special considerations:
- Files in Windows Explorer with this extension will display using a generic icon after removing the extension.
- You will not be able to open files with this extension in Windows Explorer by double-clicking on them.
Actions
The image below shows the "Remove" dialog when removing an action:

Special considerations:
- You will not be able to double-click on file of that type to open it after removing the "Open" action.
Shell Extensions
The image below shows the "Remove" dialog when removing a shell extension:

Special considerations:
- Many Windows system components, such as the "File Sharing" tab or "Security" tab, are implemented as shell extensions. Removing such a shell extension can potentially cripple your system.
- When removing shell extensions be careful. If possible simply do not approve the shell extension instead of removing it. This will have the same effect since the shell extension will not be enabled, however, you can easily re-enable it if needed.
- The approve setting for shell extensions only takes effect on Windows NT/2000/XP.
