How to Find Your Deleted Internet History After CCleaner

Updated March 23, 2017

CCleaner is a freeware program that helps you easily clean several components of your computer at once. Some of those components are temporary Internet files, history, cookies and recently typed URLs. Once these are deleted, they are not permanently gone from your computer. Rather, they are stored in a file known as the index.dat file, so if you want to find your deleted Internet history after running CCleaner, all you have to do is locate the index.dat file.

Click "Start." Click "Computer."

Click "Tools." Click "Folder Options."

Click "View." Select "Show hidden files and folders."

Deselect "Hide extensions for known file types." Click "OK."

Exit the window. Click "Start." Click "Search."

Click "All Files and Folders." Click "C Drive."

Type "index.dat" into the search bar. Click "Search."

Download an index.dat file reader to your computer. Right-click the index.dat file.

Click "Open With." Select the index.dat file reader you downloaded to read the index.dat file.

Click the "History" tab to view your deleted Internet history.


Prevent the deletion of your Internet history when running CCleaner by deselecting "History" before running the cleaner again.


Restore your file and folder defaults when you are done to prevent damaging important system files that should be hidden. Restore defaults by clicking the "Restore Defaults" button from the "Folder Options" window.
