Using CDirScan

Setting up the scan using SetScanDataL()

Taking the above directory structure, if SetScanData() is called as follows:

       
        
       
       _LIT(KDirText,"C:\\TopDir\\");
...
SetScanDataL(KDirText,KEntryAttDir,ESortByName|EAscending,CDirScan::EScanDownTree);
...
      

then the directories are scanned, by repeatedly calling CDirScan::NextL() in the following order: TopDir , Dir1 , Dir2 , Dir3 , Dir4 , Dir5 , Dir6 , Dir7 . The sort key of EAscending means that multiple directories within the same parent directory are scanned in ascending alphabetic or numeric order.

If the scan direction is upwards, i.e. CDirScan::EScanUpTree , the directories are scanned in the order: Dir2 , Dir4 , Dir3 , Dir1 , Dir6 , Dir7 , Dir5 , TopDir .

Parsing paths using FullPath()

If the full path of the entry currently being scanned is:

C:\Topdir\Middledir\Bottomdir\

and the top level directory in the scan as passed to SetScanDataL() is:

C:\Topdir\

then:

• AbbreviatedPath() returns \Middledir\

• FullPath() returns C:\Topdir\Middledir\ .
