List the files from a Directory

In order to list the files from a directory, you need to use the RFs class (RFs is a class that allows you to access the file server).

The method TInt RFs::GetDir(const TDesC& aFileSpec, TUint anEntryAttMask, TUint anEntrySortKey, CDir*& anEntryList) returns a CDir pointer, which list all file entries in directory aFileSpec (the return value should be KErrNone).

The following example creates a listing and opens all files:

RFs fileSession;
RFile file;
CDir* dirList;
TInt i;
TBuf<50> totalPath;
TBuf<30> fileName;
_LIT(KDirName, "C:\\FolderXY\\");
_LIT(KFileSpec,"C:\\FolderXY\\*.*");

//
// Connect to the file server
//
fileSession.Connect();
CleanupClosePushL(fileSession);

//
// Get the file list, sorted by name
// (Leave if an error occurs)
//
User::LeaveIfError(
     fileSession.GetDir(KFileSpec,
                        KEntryAttMaskSupported,
                        ESortByName,
                        dirList));
CleanupStack::PushL(dirList);

//
// Process each entry
//
for (i=0;iCount();i++)
{
 fileName = (*dirList)[i].iName;
 totalPath = KDirName;
 totalPath.Append(fileName);
 DoAnythingYouWantWithTheFile(totalPath);
}

//
// Close the connection with the file server
// and destroy dirList
//
CleanupStack::PopAndDestroy(2);
