How to delete your Flash cache

As you almost certainly know, Flash is a huge part of the web. Nearly every streaming video site uses it. Facebook uses it. Many of the ads you see on the web are actually Flash videos.

What you may not know, is that when you clear your browsers history, cache, passwords etc – you’re still leaving behind traces of your browsing history – in the form of the “Flash cache”. This tutorial will show you how to delete that cache – or just individual sites from it.

While this process used to be a bit more complicated, Adobe (the folks who develop Flash) have made it considerably more easy in one of the more recent versions of Flash.

  1. To get started, simply visit this page. This will take you to the Settings Manager for the Flash Player. It should also take you directly to the Website Storage Settings section. If it doesn’t, simply click the Website Storage Settings button (see screenshot below) to bring that section up.
  2. Towards the bottom of that window, you’ll see a section with a list of all the sites that have left some piece of Flash on your computer. To delete just one of the sites in the list, select it by clicking on it once, and then click the Delete website button.
  3. You’ll be prompted to confirm that you wish to delete that site – click the Confirm button.
  4. If you want to delete all of the sites that Flash has saved (the history/site-name itself, and often some Flash content) – click the Delete all sites button.
  5. Again, you’ll be prompted to confirm this action. Click Confirm.
  6. And now your computer is free of the history of sites that you have visted with Flash content.
  7. That’s it! It is of course important to note that the next time you visit a site that you had previously deleted, it will re-appear in you Flash history list.

    My Flash Player shows no settings at all and there is no information given about websites to be deleted. How can I fix this as I need to clear my cache.

    How often is it recommended to clear the cache? If you visit a certain site all the time like a games site, is it necessary to clear the cache? This is confusing to me I don’t understand the purpose of doing this? Is it just to make space on the computer?

    there is a fairly simple way to get to the page you need… When you are on a site using flash player, right click the flash player and select “Global Settings…” Then you simply should close out the browser window in which the flash player is running and then before editing your settings I recommend that you clear your browser cache and MAKE SURE you are allowing cookies to be set… Then you can click on the various tabs on the Global settings plug-in page and set your preferences for ALL sites that use the flash player…

    the confirm button will show up in a pop-up when you click “Delete ALL” so just make sure you are allowing pop-ups
