Clean browser history and cookie data

Develop a non-graphical unit that allows you to clean the temporary files / cache, cookies, browser history and download history of the following web browsers: - Internet Explorer (versions 8 and 9) - Mozilla Firefox (versions 4 and 5) - Opera (version 10 and 11) - Google chrome (version 12) The unit has two features: 1. Show the amount of data (e.g. the number of cookies stored and the amount of space they take in Firefox). 2. Clear the selected data. You must also develop a simple demo application that shows how the unit is used. The demo app has two buttons to test the two features of the unit: 1. Analyze 2. Clear Analyze button lists all the found data of the four browsers. The data can be listed e.g. to TMemo. Clear button clears all this data, i.e. deletes the cookies, clears the history, clears the temp files / cache files etc.
