<concept xml:lang="en" id="GUID-CA35A708-C6D9-51D7-873B-A79606FFAF66"><title>How to search for files with TFindFile</title><prolog><metadata><keywords/></metadata></prolog><conbody><p>The following example accumulates a list of all the files on any drive which are in a particular directory and which match a name with wildcards, for example, all files matching <filepath>\resources\fonts\*.gdr</filepath>. </p> <p>To start a search, use <codeph>TFindFile::FindWildByDir()</codeph>. You can then call <codeph>TFindFile::FindWild()</codeph> to perform the same search on another drive. </p> <p>To retrieve the fully qualified path of the matching files, class <codeph>TParse</codeph> is used to combine the filename with the drive letter and directory which contains the file. The example works as follows: </p> <ol id="GUID-E589950F-603A-5BB3-9387-06D1B2CE2E4B"><li id="GUID-A748895E-D312-505C-A2D7-3C35952F7913"><p>Construct a <codeph>TFindFile</codeph> object. </p> </li> <li id="GUID-A6DE36F9-033A-534B-A27D-A3B8FC50A8D5"><p>Use <codeph>FindWildByDir()</codeph> to start the search for matching files. There is considerable flexibility in the handling of <codeph>aWildName</codeph> and <codeph>aScanDir</codeph>, but the simplest and most common case is where <codeph>aWildName</codeph> is the filename and extension (for example, <filepath>*.gdr</filepath>) and <codeph>aScanDir</codeph> is the directory name, without a drive letter, but including a trailing directory separator (for example, <filepath>\resources\fonts\</filepath>). </p> </li> <li id="GUID-44EE24DB-880F-52A4-85E1-02C575CC6B9F"><p>The list of matching files is returned in a <codeph>CDir</codeph> object, which is implemented as an array. <codeph>Count()</codeph> retrieves the number of items in the list. </p> </li> <li id="GUID-FE931EA6-0AB0-5D5C-88ED-7E4F506DDE60"><p>Use <codeph>file_finder.File()</codeph> to retrieve the drive and path of the folder containing the files in the <codeph>CDir</codeph>, (for example <filepath>Z:\resources\fonts\</filepath>). </p> </li> <li id="GUID-67ACA73A-CDDE-5C95-8B31-4D421BE4D95D"><p>Use <codeph>TParse::Set()</codeph> to combine the file name and path into a full filename. </p> </li> <li id="GUID-B9EEB198-264B-5A82-869D-329077498849"><p>Use <codeph>TFindFile::FindWild()</codeph> to continue the search on the next drive in the search sequence. </p> </li> </ol> <codeblock id="GUID-FECFC563-7050-5A63-B29F-BF757B608818" xml:space="preserve">void ForAllMatchingFiles(RFs&amp; aSession, const TDesC&amp; aWildName,
