Here is the first one...


 
if(documents.length) resizeToFiftyMeg(); 

function resizeToFiftyMeg(){ 

var SizeOfFile = 50; //This is the actual size required. 

var current_units = preferences.rulerUnits;  

preferences.rulerUnits = Units.PIXELS;   

var width_pixels = activeDocument.width;  

var height_pixels = activeDocument.height;  

var channel_count = activeDocument.channels.length;  

var image_bytes = width_pixels * height_pixels;  

var actual =((image_bytes/1024/1024)*channel_count).toFixed(2); 

if(actual >= SizeOfFile) return; 

var final_size = ( 1024 * 1024 * SizeOfFile ) / channel_count;  

var image_scale = Math.sqrt( final_size/ image_bytes );  

var final_width = width_pixels * image_scale;  

var final_height = height_pixels * image_scale;  

var final_ppi = activeDocument.resolution; 

activeDocument.resizeImage( final_width, final_height, final_ppi, ResampleMethod.BICUBICSMOOTHER ); 

preferences.rulerUnits = current_units;  

}



and the second..

 
if(activeDocument.pathItems.length){ 
app.activeDocument.pathItems.removeAll();  
}
