The location of the file depends on your operating system. Under Windows XP the file will be located under your Local Settings\Application Data folder. Usually, this is as follows:

C:\Documents and Settings\%USERNAME%\Local Settings\Application Data

Under Windows 7 and Windows Vista the file will be located under:

%USERPROFILE%\AppData\Local

where %USERPROFILE% is the Windows user profile location.

As the cache file is marked as 'Hidden' you should enable showing of hidden files in Windows if you wish to find the file.
