220.127.116.11 Permit Read/Write in Current Directory
If turned on, the current directory (but not any below it) is automatically added to the allowed list of read/write
locations. Since POVWIN sets the current directory to that which contains the source file (.pov or .ini) at the start
of a render, this automatically enables the location containing a scene for read/write. For most people, this is a
useful feature, so it is on by default for a clean install.
Please note that having this option unchecked does not prevent read in the current directory if you have
turned off read restrictions (as documented above), and nor will it prevent writing if you have turned off I/O
Restrictions altogether. Also, turning it on will not allow read/write in subdirectories of the current directory -
just that dir alone.
