You Can use : 

QFileInfo fileInfo(m_logFilePath);
QDir dir(fileInfo.absoluteDir());
QStringList totalfiles;
totalfiles = dir.entryList(QStringList("*"), QDir::Files | QDir::NoSymLinks);

using file name 

totalfiles = dir.entryList(QStringList("filename"), QDir::Files | QDir::Names);

You'll need exclude . and .. - QDir::Files filter can help you there.

I am posting a complete answer.

QString path = "c:\test"; // assume it is some path

QDir dir( path );

dir.setFilter( QDir::AllEntries | QDir::NoDotAndDotDot );

int total_files = dir.count();

You should use flags QDir::Filters with QDir::NoDotAndDotDot

QDir.count() returns the total count of files and directories in the directory. This includes the . (this) and .. (parent) directory entries. So the count is always two more than the "real" files and subdirectories.
