How to read drivetable.txt

Hii

I wanna read the file(drivetable.txt) and write into another file.It is content of System Volume Information folder.

Code:

---

HANDLE hFile = CreateFile(
                       
                        L"C:\\System Volume Information\\_restore{D66B84B7-13C4-40ED-9116-31C56638FDB0}\\drivetable.txt",

                                        GENERIC_READ,          // open for writing
                                        0,                              // do not share
                                        NULL,                        // default security
                                        OPEN_EXISTING,      // overwrite existing
                                        FILE_ATTRIBUTE_SYSTEM , //  file type                                         
                                        NULL);                  // no attr. template

        if (hFile == INVALID_HANDLE_VALUE)
        {
                printf("Could not open file (error %d)\n", GetLastError());
                goto lLabel;
        }

Thanking you

first, you say you want to read a file, but in your comments you say "// open for writing". also, you say "// overwrite existing" where these comments don't correspond to your code. if your comments are incorrect, it could be possible your actual code is also incorrect.

next, what does "But the given code is not working...." mean? is your code compiling? is it getting to the 'createFile' line in your code? upon running that code, what happens? runtime error? does it get into the "hFile == INVALID_HANDLE_VALUE" block? if it gets into this block, what is the error code/message? did you look this error code up on msdn? could tell us what error code and description you are receiving ? etc, etc
