I am writing an HTML5-Javascript video game. I want to save 2 files to PERSISTENT localStorage: one file can be 20MB in size... I have tried to increase the 5MB storage limit to 15MB & it does work. I have tried:

to SET max limit: window.webkitStorageInfo.requestQuota( 

           window.PERSISTENT,
           15000000,
           function( bytes ) {
               alert( "Quota is available: " + bytes );
           },
           function( e ) {
               alert( "Error allocating quota: " + e );
           });

and to READ current usage:

window.webkitPersistentStorage.queryUsageAndQuota ( 

   function(usedBytes, grantedBytes) {  
       alert('we are using '+ usedBytes+ ' of '+ grantedBytes+ ' bytes');
   }, 
   function(e) { alert('Error'+ e);  }

);

Try window. & navigator.webkit... I get error "webkit... undefined"

HELP??????

try this:

  1. tape about:config in your url bare
  2. Accept by clicking on the button
  3. search dom.storage.default_quota
  4. update the value (in Kb)

If I were you, I would simply use this during my tests.
