I am using the following code to open a text file

CStdioFile f;

CString sPath = "E:Foldertest.txt"  
                                      
//Open the text file
if (f.Open(sPath, CFile::modeRead))
{
     int i = 0;
}

This works.

However the text file I need to read is located in the C: drive. If I set sPath to “C:Foldertest.txt” the program no longer opens the file. Note that the program itself is located in the E: drive.

I verified that the user running the program has read access to C:Foldertest.txt. I would expect to be able to open this file given that the user has read permissions, but I am unable to do so.
