Description

===========

ChromeCacheView is a small utility that reads the cache folder of Google

Chrome Web browser, and displays the list of all files currently stored

in the cache. For each cache file, the following information is

displayed: URL, Content type, File size, Last accessed time, Expiration

time, Server name, Server response, and more.

You can easily select one or more items from the cache list, and then

extract the files to another folder, or copy the URLs list to the

clipboard.

The Location Of Chrome Cache Folder

===================================

The cache folder of Google Chrome is located under [User Profile]\Local

Settings\Application Data\Google\Chrome\User Data\Default\Cache

System Requirements

===================

* This utility works on any version of Windows, starting from Windows

2000, and up to Windows 7/8/2008/10/11.

Using ChromeCacheView

=====================

ChromeCacheView doesn't require any installation process or additional

DLL files. Simply copy the executable file (ChromeCacheView.exe) to any

folder you like, and run it.

After you run it, the main window displays the list of files currently

stored in the cache of the default Google Chrome user.

You can select one or more cache files from the list, and then export the

list into text/html/xml file ('Save Selected Items' option), copy the URL

list to the clipboard (Ctrl+U), copy the entire table of cache files

(Ctrl+C), and then paste it to Excel or to OpenOffice spreadsheet. You

can also extract the actual files from the cache, and save them into

another folder, You can do that by using the 'Copy Selected Cache Files

To' option (F4).

Starting from version 2.10 - When you select image cache item ( gif, png,

jpg) or text-based cache item (HTML, CSS, JSON, Javascript), you can

watch the content of the cache file in the lower pane if the 'Show

Preview Pane' option is turned on (View -> Show Preview Pane or simply

press F8).
