|
|---|
| 12 | <h3>Description</h3>
|
|---|
| 13 | <p>Deletes a single file, a specified directory and all its files and
|
|---|
| 14 | subdirectories, or a set of files specified by one or more
|
|---|
| 15 | <a href="../CoreTypes/fileset.html">FileSet</a>s.
|
|---|
| 16 | When specifying a set of files, empty directories are <i>not</i> removed by
|
|---|
| 17 | default.
|
|---|
| 18 | To remove empty directories, use the <code>includeEmptyDirs</code> attribute.
|
|---|
| 19 | </p>
|
|---|
| 20 | <p>
|
|---|
| 21 | If you use this task to delete temporary files created by editors
|
|---|
| 22 | and it doesn't seem to work, read up on the
|
|---|
| 23 | <a href="../dirtasks.html#defaultexcludes">default exclusion set</a>
|
|---|
| 24 | in <strong>Directory-based Tasks</strong>, and see the
|
|---|
| 25 | <code>defaultexcludes</code> attribute below.
