Browser Cache Files and web archives

View Safari Cache

Extract and View Cache Files

Browser caches can contain all file formats, and with File Juicer you can extract most of it. Pick the cache you wish to extract and view the results in Finder afterwards.

Safari's cache files once (about 2014) had the extension .cache, but today they are extensionless files named with a UUID (Universally Unique Identifier)

Web Archives

File Juicer extracts the contents of web archives. Safari's web archive has the extension .webarchive and everything is extracted for these files.
FireFox use .dat for cache and saves web archives as separate files in a folder.
Google Chrome strips extensions from files in the cache, but File Juicer can extract the files anyway. More about the Google Chrome Cache.
Opera stores the files as is, which means you can dig through the cache with Finder, but to get a quick overview File Juicer makes index files and sorts extracted images according to type and it will be much easier to browse through.

Internet Explorer use .waf for cache files and 'WAFF' files as web archives. It has the added feature that you can download a web page and follow links up to 5 levels deep, and download those pages too. File Juicer can extract the images and html from this file.

Where to find the Cache files of Safari, Firefox and other Applications?

The location of cache files is in your ~/Library/Caches/ folder. Shortcuts to the most common browser caches are in File Juicer, but if you need to extract from other applications which use the same caching mechanism as Safari you can find them here, and drag them onto File Juicer.

How Do I Open The Caches Folder?

The Caches folder is inside your hidden Library folder. In finder you pick Go from the menu while holding down the alt-key. Then the Library folder will show up and you can find the Caches folder.

Which Types of Files are Found in the Cache?

The files in the Cache are images, text, layout and code. However, the cahced files may not have type identification or the data may be stored inside some undocumented format. Here File Juycier will help you by properly identifying and extracting standatd data types like JPG and GIF.

How About FLV files from YouTube or other sites?

Flash video files are not cached in the normal browser caches, but the Flash Plugin puts them in the hidden Temporary Items folder, which you can also juice directly from File Juicer. The files are there only temporarily, and they are cleaned up automatically when you leave the web page or start another video clip.

You can also get to these files directly with Safari's "Activity" menu item.

Recover lost HTML from browser or Google caches

Recover files form Google Cache If write HTML and by accident delete your work, you may recover the files if you test your pages in a web browser.

If the page you are editing has been indexed by Google, you can also find it there. Type in the URL for your page in the Google search field and follow the "Show Google's Cache" link.
