Hi,
I created the folder structure without files.
When NeroBurn is called, i receive an error: "log line: access is denied", and my folders are listed there. The application crashes.

Thanks in advance.

I assume you are using NeroAPI. Can you show the code where you build the tree? Are you allocating NERO_ISO_ITEMs using NeroCreateIsoItem()?

Thanks for your reply
Everything seems ok on debugging....but doesn't work
Here is the function

NERO_ISO_ITEM *firstItem,*itItem;
//cauta folderul
//=0 daca nu-l gaseste
//>0 daca il gaseste
// build a string with wildcards
CString strWildcard(folderName);
strWildcard += _T("\\*.*");

// start working for files
BOOL bWorking = finder.FindFile(strWildcard);
CString str;
//adaug prima serie
while (bWorking)
{
bWorking = finder.FindNextFile();

// skip . and .. files; otherwise, we'd
// recur infinitely!

if (finder.IsDots())
{
continue;
}

// if it's a directory, recursively search it

//cauta toate folderele de aici si adauga-le pe aceeasi ramura
