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.



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).

    added under the toolbar and ChromeCacheView will instantly filter the
    cache items, showing only lines that contain the string you typed.

* Version 1.70:
  o Added new buttons to easily choose the cache folder of
    Chrome-base Web browsers: 'Vivaldi Cache Folder', 'Yandex Cache
    Folder' , and 'Chrome Cache Folder' (Advanced Options window).

* Version 1.67:
  o Fixed issue: When loading large amount of cache items, some
    actions, like selecting items and copying selected items to the
    clipboard were very slow.

* Version 1.66:
  o Added 'URL Length' column.

* Version 1.65:
  o Fixed bug: ChromeCacheView failed to retrieve some of the long
    URLs.

* Version 1.62:
  o Added 'Opera Cache Folder' button to the 'Select Cache Folder'
    window, which allows you to easily use this tool to view the cache of
    Opera Web browser. (Opera is now based on the code of Chrome Web
    browser...)

* Version 1.61:
  o The 'Cache Name' column now displays information about cache
    files stored inside data files (data_1, data_2, data_3 ...). It
    displays the filename and the position the the file stream is stored.

* Version 1.60:
  o Fixed to find the correct item when typing the string you want to
    search into the main List View.
  o Added secondary sorting support: You can now get a secondary
    sorting, by holding down the shift key while clicking the column
    header. Be aware that you only have to hold down the shift key when
    clicking the second/third/fourth column. To sort the first column you
    should not hold down the Shift key.

  o Fixed bug: ChromeCacheView failed to copy the cache files if
    'Save the files in the directory structure of the Web site' option
    was turned on and the Web site used non-standard TCP port (Instead of
    port 80).
  o Fixed to display date/time values according to daylight saving
    time settings.

* Version 1.55:
  o Fixed issue: ChromeCacheView loaded only 4 data files: data_0,
    data_1, data_2, data_3. It seems that when the cache of Chrome is
    large enough, it starts to create more cache data files (data_4,
    data_5...)
    Starting from this version, ChromeCacheView will read these
    additional cache data files.

* Version 1.50:
  o Added 'Load only files larger than...' and 'Load only files
    smaller than...' options. (In 'Select Cache Folder' window)

* Version 1.46:

    compressed with gzip.
  o Fixed issue: ChromeCacheView left multiple files under the temp
    folder when extracting files compressed with gzip.

* Version 1.45:
  o ChromeCacheView now loads the cache items much faster and with
    less memory usage, especially if you have a large amount of items in
    the cache.

* Version 1.40:
  o Added 'Stop' menu item, which allows you to stop the loading
    process of the cache files list.

* Version 1.35:
  o Added 'Load only cache files from the last xx days' option (In
    'Select Cache Folder' window).
  o Added 'Load only cache files in the following time range' option
    (In 'Select Cache Folder' window).

* Version 1.30:
  o Added 'Open Selected Cache File' option, which opens the selected
    cache file with the default file viewer.
  o Added 'Double-Click Action' option, which allows you to choose
    what to do when you double-click on cache item.

* Version 1.27:
  o The status bar now displays the total size of selected files in
    KB/MB.

* Version 1.26:
  o Fixed ChromeCacheView to read the cache when the latest version
    of Chrome is opened and locks the cache files.

* Version 1.25:
  o Added /copycache command-line option, which allows you to extract
    files from the cache without displaying any user interface.
  o Also added /CopyFilesFolder, /UseWebSiteDirStructure, and
    /NewNameIfExist command-line options, for using with the /copycache
    command-line option.

* Version 1.22:
  o Made a small fix that hopefully will solve a crash problem that
    some users experienced.
