Now it also pushes the length of the file read before the content of the
file

 ### **File Reader (r)**
 Supports northeast, north, northwest, west and southwest directions. Continuously pops the value on top of the stack and constructs a filename from those values until either it hits a zero or the stack becomes empty. (If it hits a zero, it also pops that)  
-Then reads the file with that filename in binary mode and pushes its content on top of the stack in reverse order, meaning the first character of the file will be the value on top of the stack. If it fails, it pushes zero to the stack.
+Then, it reads the file with that filename in binary mode, pushes its content on top of the stack in reverse order and the length of the string. If it fails to open the file, it only pushes a zero to the stack.
 
 ### **File Openers**
 Similar to File Reader, File Openers read a filename from the stack in the same way. After opening the file, they push a positive integer as unique identifier that can be used to communicate with file.
