Copy a file?

Hi i was wondering if anyone knew how I can copy a file (with C++) and then place it in a folder and overwrite a file in that folder with the same name.

Thanks

Edit: Oh yea, and i was wondering how i could open a file that has a space in the folder name like.. C:\Documents and Settings\default\My Documents how can i write that in C++ Coz it doesnt let me do spaces

See the CopyFile() and CopyFileEx() documentation in MSDN

There should be no problems in using spaces in filenames with these functions.

Hi, Sorry if i should newb but in order to copy a file, i have this code..

Code:

BOOL CopyFile(
  LPCTSTR lpExistingFileName,
  LPCTSTR lpNewFileName,
  BOOL bFailIfExists
);

but... do i just leave lpExistingFileName as that? or do i change it with like C:\Whatever\I\Want\To\Copy

Thanks in advance.

My experience, which is limited, is that you need to use double backslashes because of real expressions.
Example: C:\\Whatever\\I\\Want\\To\\Copy

You can just use something like this:

Code:

CopyFile("C:\\path\\to\\source\\file", "C:\\path\\to\\destination\\file", FALSE);

If you don't understand what this LPCTSTR business is all about, I suggest you research Hungarian Notation on the web, or look it up in a Visual C++ programming book. Practically all of Micro$oft's code uses Hungarian Notation as their standard naming convention and it's good to become slightly familiar with it.
