How To Delete Index.dat file? [User Recommendation]
By on July 9th, 2008

This post is part of the user recommendation marathon where users recommend their questions to us.

Our regular reader Vishnu asks us, I have heard about Index.dat files and that they can store lots of information about the sites I browse, is there a way I can get rid of the files so that no one can know which sites I have browsed

Hi Vishnu, thanks for taking the time to ask us this question. We will detail in this post, how you can delete index.dat files to get rid of your Internet activities and history.

Index.dat files are basically data files that can contain information about the sites you visited using Internet Explorer. The file acts as a database of information about your browsing habits and includes URLs you visited, cookies, search queries and files you opened using the browser.

That said privacy has always been a concern with index.dat files, since they cannot be deleted easily using the regular methods. The best and easiest way to delete index.dat file is by using CCleaner, a free software that helps you clear unwanted information from your PC.

Once you have downloaded and installed CCleaner, run the software and choose the option to delete index.dat file by selecting it from the options under Internet Explorer, once you have selected or de-selected the other options click on the button to run the cleaner.


After the cleaner has completed, the index.dat file will not hold any information from your previous browsing solving your privacy concerns.

There are several softwares which charge you for doing the same thing, but like always we find a better solution. So the next time you have a query or a question, you know the best way to figure it out, contact us with your queries and we will try our best to find the best solution for it.

Hope this answered your question Vishnu, feel free to send us your queries anytime.

Download CCleaner

    ^^ In firefox: Tools-> Options -> Privacy -> Show cookies. Now search for the site and then delete the entries shown.

    In Vista for IE you can try this:

    C:\Users\\AppData\Local\Microsoft\Window s\Temporary Internet Files

    Then delete the cookie files.

    I used CC cleaner a while back to help remove some spyware files that had been left behind. Very good product, did the trick.

    CCleaner is not a free software. Why did you write a lie to help delete Index.dat files…..

    • Keith Dsouza

      @Renaud – CCleaner is a free software, you can download it for free from absolutely free of cost. If someone is selling you CCleaner for a price, it is a scam, do not buy it from them

    Microsoft is so desperate to keep you away from Index.dat files that they keeps moving the goalposts via service packs and new versions of windows so what worked yesterday, won’t work today.

    Some of the ‘Special Hidden’ folders won’t show even when you use a registry hack and killing processes ‘Explorer’ and ‘IExplorer’ before you try to delete them still won’t unlock the files on Win 7 X 64 (Build 7600) and running batch files without exposing account names and passwords cannot remove these index.dat files at reboot due to the wrong windows permissions.

    One method that might still works is to boot-up in safe mode and then assign yourself administrator rights and then see if you can find the files to delete or use a batch file to rename the subfolder below the folder containing the index.bat files and to then only copy the folders back to the original location that don’t contain these Spyware files but the resultant batch files needs to be run from a separate windows account that has administrator permissions.

    Do you have any tips, software (open source), and/or add-ons to help us keep most of our movement(s) on the Internet from being tracked by the NSA’s Prism Program?, other than the obvious to just not go online?
