Programmatically deleting a file
[158 byte] By [JamesP] at [2007-11-17 0:46:59] 
I am holding a path of a file in a variable and I want to ensure that this file doesn't exist before I continue. How you programmatically delete a file?
# 1 Re: Programmatically deleting a file
Check out the DeleteFile(...) function. e.g.BOOL DeleteFile(LPCTSTR lpFileName // pointer to name of file to delete
);

To know if a file exists, you can use fopen:FILE *fp;
if((fp=fopen("nomefile.dat","rb"))!=0)
{
// here the file exists
// and you can delete it
}

...or, yet another way:remove("c:\\myfile.txt");Don't you love C++?

And another way to check if file exists before deleting it...CString csFile="c:\\myfile.txt";
if (!_access(csFile,0))
remove(csFile);
hope this helps.
