How to recurses all subdirectories in a root directory and list out the name of these directories.
We can use CFileFind MFC class to find the files from a folder and call a member function IsDirectory of this class to determine if the found file is a directory.
bool FindSubFolders()
{
CString rootFolderPath = _T("D:\\SAN");
std::vector& subFolderList;
CFileFind finder;
bool returnValue = false;
char fileName[_MAX_PATH];
strcpy(fileName, rootFolderPath);
strcat(fileName, _T("\\*.*"));
BOOL bOk = finder.FindFile(fileName);
while (bOk)
{
bOk = finder.FindNextFile();
/** skip . and .. files */
if (finder.IsDots())
{
continue;
}
/** Add to list if its a directory */
if (finder.IsDirectory())
{
subFolderList.push_back(finder.GetFilePath());
returnValue = true;
}
}
finder.Close();
return returnValue;
}
A file that is a directory is marked with FILE_ATTRIBUTE_DIRECTORY a file attribute identified in the WIN32_FIND_DATA structure.

With your code only list a sub folder (not all sub folder) !!!
Ex:
D:\
A
1
2
B
3
4
C
5
6
You only can get folder (A,B,C) from root folder (D:\).
You can not get all sub folder.
If you can get all sub folder, please help me by sending email to me !!!
Thank you in advance !!!
Hello,
Thanks for your comment.
If you need to get the list of all the sub-folders too, you can recursively call the same function with a small change… please see the code snippet below.
std::vector m_subFolderList;
bool FindSubFolders(CString p_strFolderPath)
{
CFileFind finder;
bool returnValue = false;
char fileName[_MAX_PATH];
strcpy(fileName, p_strFolderPath);
strcat(fileName, _T(“\\*.*”));
BOOL bOk = finder.FindFile(fileName);
while (bOk)
{
bOk = finder.FindNextFile();
/** skip . and .. files */
if (finder.IsDots())
{
continue;
}
/** Add to list if its a directory */
if (finder.IsDirectory())
{
m_subFolderList.push_back(finder.GetFilePath());
returnValue = true;
}
FindSubFolders( finder.GetFilePath() );
}
finder.Close();
return returnValue;
}
void FindAllSunFolders()
{
FindSubFolders (“F:\\RootFolder”);
std::vector::iterator itr = m_subFolderList.begin();
std::vector::iterator itrEnd = m_subFolderList.end();
while (itr != itrEnd)
{
AfxMessageBox(*itr);
++itr;
}
}
Thanks
