### 1.2.1 I/O Restrictions

Note: The I/O Restriction code may not be completely mature yet. Please report any bugs you may find.

The Unix platform specific part of the I/O Restrictions feature has been redesigned for POV-Ray 3.6. The configuration file format has changed as well as the way the settings are interpreted. How the I/O Restriction can be controlled in the Unix version is described in the I/O Restrictions Documentation.

As a quick summary, I/O Restrictions control where the POV-Ray core code may and may not read or write files. By default, this is turned on and is fairly restrictive (read/write is allowed in the directory that the main input file is in, and read is allowed in the standard installation directories).
