+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 \resources\fonts\*.gdr.
+To start a search, use TFindFile::FindWildByDir(). You
+can then call TFindFile::FindWild() to perform the same search
+on another drive.
+To retrieve the fully qualified path of the matching files, class TParse is
+used to combine the filename with the drive letter and directory which contains
+the file. The example works as follows:
+
+Construct a TFindFile object.
Use FindWildByDir() to
+start the search for matching files. There is considerable flexibility in
+the handling of aWildName and aScanDir,
+but the simplest and most common case is where aWildName is
+the filename and extension (for example, *.gdr) and aScanDir is
+the directory name, without a drive letter, but including a trailing directory
+separator (for example, \resources\fonts\).
The list of matching
+files is returned in a CDir object, which is implemented
+as an array. Count() retrieves the number of items in the
+list.
Use file_finder.File() to
+retrieve the drive and path of the folder containing the files in the CDir,
+(for example Z:\resources\fonts\).
Use TParse::Set() to
+combine the file name and path into a full filename.
Use TFindFile::FindWild() to
+continue the search on the next drive in the search sequence.
+void ForAllMatchingFiles(RFs& aSession, const TDesC& aWildName,
+ const TDesC& aScanDir)

+ TFindFile file_finder(aSession);
+ CDir* file_list;
+ TInt err = file_finder.FindWildByDir(aWildname,aScanDir, file_list);
+ while (err==KErrNone)
+ {
+ TInt i;
+ for (i=0; i<file_list->Count(); i++)
+ {
+ TParse fullentry;
+ fullentry.Set((*file_list)[i].iName,& file_finder.File(),NULL);
+ // Do something with the full filename...
