Index Manager enables you to control the display of directories on your website.

Index Manager needs to be setup for clients directory. There are four options to be chosen from. Default System Setting: It will allow directory contents to be shown; No Indexes: Doesn"t allow directory contents to be shown; Standard Indexing (text only): Prevents browsers from viewing the contents of directories that don"t contain image files; Fancy Indexing (graphics): Prevents browsers from viewing the contents of directories that do contain image files.
