The Show and Hide Filter allows you to define exactly what items will be shown in the file display by matching a name pattern or file Attribute. You can specify separate filters for files and folders. For example, the filter to the right is designed to show only a limited range of images files - those with file extensions of .jpg or .bmp, or .gif. The wild cards which may be used for the file name pattern are *, #, ?, |, (), [], ~ or single quote. See Pattern Matching Syntax in the Appendix for more details.
