My idea is that this function either returns true if the file is present, or false if its not, any sugestions?

If you are writing for Windows only (not cross-platform) you should use the safe string routines

strcpy == StringCchCopy[^]

You should be aware that strsafe functions, such as StringCchCopy and StringCchCat behave 
differently than strncpy_s and strncat_s. If strncat_s detects an error, the function will 
set the string to NULL. However, by default, strsafe will fill the destination with as much 
data as possible, and then NULL-terminate the string. You can mimic the same behavior in 
strsafe with code like this:
