search dlls files in Series60 3rd edition...

hello,
I have an S6- 3rd edition application.

i need to search for my application, dlls plugins in \sys\bin\ folder because i understood that only from this folder i can then load them correctly in S60 3rd edition.

now my problem is how to find dlls in this folder, \sys\bin\ , because using FindWildByPath method always return -1 error code, when using this folder.

if i use another dlls path( \ myapp\plugins\ for example) the FindWildByPath method works correctly returning KErrNone.

My question is how to find dlls in \sys\bin\ folders ?

I've used the following code:

...................................
//_LIT(KPluginsDir,"\\myapp\\plugins\\");
_LIT(KPluginsDir,"\\sys\\bin\\");
_LIT(KWildFind,"*.dll");


...................................
// open file server session
User::LeaveIfError(iFs.Connect());

TFindFile findFile(iFs);
CDir* dirList = NULL;
TInt err;
TFileName pluginsPath;
// the next line return the drive letter (c: or e: for example)
pluginsPath = NEikonEnvironment::ApplicationDrive();
pluginsPath.Append(KPluginsDir);

TFileName fullName;
err = findFile.FindWildByPath(KWildFind,&pluginsPath,dirList);

// search all the dlls from the current folder...
while(err==KErrNone)
{
TFileName path = findFile.File();

if(path.Length()>3)
{
for(TInt i=0; i<dirList->Count(); i++)
{
TParse fileName;
fileName.Set((*dirList)[i].iName,&path,NULL);
fullName = fileName.FullName();

.........................
}
}
delete dirList;
dirList = NULL;
err = findFile.FindWild(dirList);
}
delete dirList;
