Enable windows file extensions
To enable display of Windows file extensions in windows explorer and most file open and file save dialogs:
- Open Windows Explorer
- Choose Tools -> Folder Options... from the Menu
- Select View tab page
- Under Advanced Settings uncheck Hide file extensions for known file types
- Click Ok
This won't enable the display of all file extensions (.PIF and .LNK will be still hidden for example) but it will make working with different image file types much easier...
