How to Repair Corrupted Files

How to Repair Corrupted Files. When efforts to open or delete a file fail, usually it is because the file is corrupted. Files become corrupted from application failures or system crashes. If the problem persists even when no crashes have taken place, the cause could be due to a virus infection. File corruption can also result from flaws in the hard drive's file system sector or the hard drive itself. Fortunately, damaged files are almost always salvageable, even if they haven't been backed up automatically.

      Restore the lost file from a recent backup. Many programs create backups automatically. Microsoft Word, for example, backs up ".doc" files as ".wbk" files under the same folder. In this case, rename the ".wbk" file as ".doc" to open it.

      Utilize the System Restore tool after an installation or accidental disk format. A feature of Windows XP and Millennium, it rolls system files back to an earlier state when everything worked. Software installations, updates or removals sometimes make unwanted changes to the system.

      Hire a data recovery expert to match data fragments of corrupt files to fix data that software can't piece together. This should be the last resort after all attempts with software like those recommended above have failed. As the cost of hiring data recovery experts is very high, this measure is appropriate when the data is completely irreplaceable and its value is very high.

Tips & Warnings

  • Backing up frequently and letting an anti virus software run in the background are two precautions that can save you from losing files and data.

  • Third party software typically works like this: Download the demo. Install it. Run it on the target file. The software tells you if the file is salvageable. For the actual repair to be performed you have to buy the product license which can cost you from $30 to several hundred dollars.

  • Do not save or install programs after you realize that a file has been lost. Save and install operations can write over the "ghost file" that may be spread over many memory clusters.
