File.SetAttributes

File.SetAttributes (

Example 1

-- get the file's current attributes
attrib = File.GetAttributes( _TempFolder .. "\\MyTempFile.tmp" );

-- override a couple of the values in the table
attrib.ReadOnly = true;
attrib.Hidden = false;

-- set the modified attributes back to the file
File.SetAttributes( _TempFolder .. "\\MyTempFile.tmp", attrib );

Sets the ReadOnly attribute and unsets the Hidden attribute of the MyTempFile.tmp file located in the user's temp folder, leaving all other attributes the same.

Example 2

-- create an empty table
attrib = {};

-- add two elements to it ("ReadOnly" and "Hidden")
attrib.ReadOnly = true;
attrib.Hidden = false;

-- apply those attributes to the file
File.SetAttributes( _TempFolder .. "\\MyTempFile.tmp", attrib );

This does the same thing as example 1: it sets the ReadOnly attribute and unsets the Hidden attribute of the MyTempFile.tmp file located in the user's temp folder, leaving all other attributes the same.

Example 3

-- change two attributes in the file by creating a table "on the fly"
File.SetAttributes( _TempFolder .. "\\MyTempFile.tmp", {ReadOnly=true, Hidden=false} )

This does the same thing as examples 1 and 2: it sets the ReadOnly attribute and unsets the Hidden attribute of the MyTempFile.tmp file located in the user's temp folder, leaving all other attributes the same.

Note: The {ReadOnly=true, Hidden=false} part creates a "temporary" table with ReadOnly and Hidden elements set to true and false, respectively. This is just like creating a named table (like attrib in the examples above) and then passing it to the action by its name. The only difference is that this table doesn't have a name. It's basically just a one-off.
