How to get file name from a full path

zengkun100

Suppose the full path is : C:\Program Files\codeproject.txt I want to extract the file name codeproject.txt. Of course I can use CString class to find the last '\', and then Mid to get the filename, but is there some API can do this daily job? Thank you :)

Since you want to use API (Windows SDK), the function below meets your need. But CFile is even convenient for you though.

BOOL GetFileInformationByHandleEx(
HANDLE hFile,
FILE_INFO_BY_HANDLE_CLASS cls,
LPVOID info,
DWORD bufsize
);
// ...
FILE_NAME_INFO MyStruct = {0};
bool b = GetFileInformationByHandleEx(hFile, FileNameInfo, &MyStruct, sizeof(FILE_NAME_INFO));

OK, Thank you Maxwell Chen :) Both of the ways you suggested are convenient. But the question is all of them need a file HANDLE. I just want to get the filename given its fullpath.

Thank you nave! I think I have got the answer:_splitpath :)

You can use the CFileFind CFileFind cf; cf.FindFile("C:\\Program Files\\codeproject.txt"); cf.FindNext(); CString strFileName = cf.GetFileName(); Rgds Abhay..

Though some API's have been mentioned above by our codeproject friends, u can also write such functions. If u know 'C' language very well and ofcourse, its basics (people having lot of experience also doesn't know the basics), u can easily write such functions. Though u got the API, still I'll strongly recommend u to try writing such function.

Less u write, less will be the bugs...

If basics are not clear and don't have confidence, then better don't write (such simple function) and drop the programming profession.

I do have written a function to do make the job done, but I still want to know is there some exist functions can do this job for me. :)

cool man..I just said one truth regrding the programming field. How ever I still remeber one bug while trying to extract the file name from path. We were extracting the file name by reverse finding the "\". But later a bug was reported and reason was that, in one secnario in the path input to that function, instead of "\", seperator was "/" :(

That's right Naveen. BTW, how many yrs of experience do u have in VC++? Do u have any Skype/Yahoo id?

_splitpath() is better option.

Write no code and you'll have absolutely no bugs. :-\

You may use PathFindFileName() like this:

TCHAR \*szPath = \_T("C:\\\\Program Files\\\\codeproject.txt");
AfxMessageBox(PathFindFileName(szPath));

#include <Shlwapi.h>; #pragma comment(lib, "shlwapi.lib") LPTSTR lpszFileName = PathFindFileName(szPath);

MSDN Says: _splitpath is deprecated because more secure versions are available, see _splitpath_s, _wsplitpath_s.
