Code:

ifstream ReadFile;
ofstream WriteFile;

//Open a file in an absolute folder
ReadFile.open("C:\\MyFolder\\MyFile.ext", ios::in);

//Open a file in a subfolder (from the one the exe is in)
WriteFile.open("MyFolder\\MyFile.ext", ios::out);

For WriteFile, shouldn't it be ios::out?

Code:

ofstream test;
test.open("C:Program Files\\Phonebook\\filename.txt", ios::out);
test<<data;  //inputs a string into the file data is a character array
test.close();

fstream test1;
test1.open("C:Program Files\\Phonebook\\filename.txt", ios::in);
test1>>str; //retrieves string inputted to the file and stores it 
                    //as str( a character array)
test.close();

for some reason the file is not being created
Anyone know why?

err sorry the \\ is in my program code(just not in the post) still doesn't work tho

Also, is the ios necessary?

Code:

ofstream test;
test.open("C:\\Program Files\\Phonebook\\filename.txt", ios::out);
test<<data;  //inputs a string into the file data is a character array
test.close();

fstream test1;
test1.open("C:\\Program Files\\Phonebook\\filename.txt", ios::in);
test1>>str; //retrieves string inputted to the file and stores it 
                    //as str( a character array)
test.close();

Try this and see what happens:

Code:

ofstream test;
test.open("C:\\Program Files\\Phonebook\\filename.txt", ios::out);
if(test.fail())
{
   cout << "Unable to save!" << endl;
   return 0;
}
test<<data;  //inputs a string into the file data is a character array
test.close();

fstream test1;
test1.open("C:\\Program Files\\Phonebook\\filename.txt", ios::in);
if(test1.fail())
{
   cout << "Unable to load!" << endl;
   return 0;
}
test1>>str; //retrieves string inputted to the file and stores it 
                    //as str( a character array)
test.close();

Hm weird, outfiles rarely fail since if they exists they are overwritten, and if they don't exists they are created. Are you sure the folder (Program Files/Phonebook) exists?

It's there, and if it wasn't then shouldn't it be created anyways?

I took out the ios:

ut and the ios::in, then changed the file and folder names to be 8 characters or under(im using Borland Turbo C++ ver 3.0, a dos based compiler). That solved the problem

Code:

test.open("C:\\PB\\filename.txt");
if(test.fail())
{
   cout << "Unable to save!" << endl;
   return 0;
}
test<<data;  //inputs a string into the file data is a character array
test.close();

fstream test1;
test1.open("C:\\PB\\filename.txt");
if(test1.fail())
{
   cout << "Unable to load!" << endl;
   return 0;
}
test1>>str; //retrieves string inputted to the file and stores it 
                    //as str( a character array)
test.close();
