<concept id="GUID-5B50E929-5C29-5920-965E-24F6CB616AC9" xml:lang="en"><title>Management

and searching</title><shortdesc>This topic describes the classes that provide high

level file system functions which can operate on files and directories located

throughout a directory hierarchy and which can take some time to complete.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The classes provide services to:</p>

<ul>

<li id="GUID-9B28F1D4-CE2A-5037-BE14-55B69403390B"><p>scan through a hierarchy,

upwards or downwards, returning a filtered list of the entries contained in

each directory</p> </li>

<li id="GUID-CFDED758-5F8C-5DF1-83A7-B6774E9243D3"><p>carry out file management

operations on files and directories in the hierarchy, for example, deleting

an entire directory structure or moving a group of files</p> </li>

<li id="GUID-6B959F2A-B707-5F12-9BCD-C70CA33C9126"><p>search for each occurrence

of a filename in one or more directories.</p> </li>

</ul>

<p>File management is provided by <codeph>CFileMan</codeph> class. Its functions

may operate recursively or non-recursively and accept the use of wildcards.

Synchronous and asynchronous variants are provided for each of these functions

and the use of the <codeph>MFileManObserver</codeph> protocol allows user

notification to take place during the operation.</p>

<p><codeph>TFindFile</codeph> and <codeph>CFileMan</codeph> classes support

the use of wildcard characters. An asterisk indicates any number of characters,

and a question mark indicates a single character. Note that in the context

of these classes, <codeph>*</codeph> and <codeph>*.*</codeph> are equivalent

and match to all files, with and without extensions. Filename matching is

case insensitive.</p>

<p>Before using any of these classes, a connection to a file server session

must have been made and is passed to the constructor of the class. </p>
