Use Properties|Ignore Patterns to add, change or delete local ignore patterns for a directory. Local ignore patterns define file and directory patterns to be ignored within the directory.
Local ignore patterns are stored within the working copy (in the svn:ignore property of the directory) and will be committed. Therefore ignore patterns can only be applied to versioned directories.
By default, the Patterns are only set to the selected directory. You may also choose to set the patterns to all subdirectories by Recurse into subdirectories. In case of recursive ignore patterns, you may alternatively consider to specify global ignore patterns within the project settings .
To add an ignore pattern, you can also use the Modify|Ignore command.
