File to open
If true, the Valve file system will be used instead

Opens or creates a file, returning a file handle on success. File handles
should be closed with fclose().
The open mode may be one of the following strings:
"r": Open an existing file for reading.
"w": Create a file for writing, or truncate (delete the contents of) an
existing file and then open it for writing.
"a": Create a file for writing, or open an existing file such that writes
will be appended to the end.
"r+": Open an existing file for both reading and writing.
"w+": Create a file for reading and writing, or truncate an existing file
and then open it for reading and writing.
"a+": Create a file for both reading and writing, or open an existing file
such that writes will be appended to the end.
The open mode may also contain an additional character after "r", "w", or "a",
but before any "+" sign. This character may be "b" (indicating binary mode) or
"t" (indicating text mode). By default, "text" mode is implied. On Linux and
Mac, this has no distinction from binary mode. On Windows, it causes the '\n'
character (0xA) to be written as "\r\n" (0xD, 0xA).
Example: "rb" opens a binary file for writing; "at" opens a text file for
