Best Methods to Repair Corrupted Files on Windows

Everything we store in a digital storage device is in the form of a file. It is the computer’s paper to read and write anything. Files come in many formats known as Extensions, used for storing different kinds of data.

But with the existence of files comes file corruption, which makes them unusable. This is a serious problem because some files contain our important stuff and we cannot afford to lose them. To solve this issue, there are various methods available which we will discuss in a few minutes.

Before that, let’s quickly check out a few reasons which can lead to file corruption.

Common Reasons for File Corruption on Windows

File corruption can occur due to many reasons, some of which are listed below. A corrupt piece of data cannot be executed or previewed unless it is repaired. So, it is essential to know what caused the corruption before starting the repair process.

1. Intentionally Corrupting Files

Corrupting files manually is a great method to prevent other people from accessing the data it contains. It is a way of protecting your sensitive content. You can check how I corrupt my file and later uncorrupt it to access the contents.

2. Virus Infection

A computer infected with a virus can result in its hard drive’s data getting corrupted if the virus is not removed.

3. Disrupted Transfer

If a data transfer is terminated midway, it can lead to a broken item in the computer or the storage drive. A disrupted download process from the internet (due to connectivity issues, etc.) might also result in a corrupt file in the Downloads folder.

4. Improper Removal of Storage Device while in use

If a storage device is not ejected correctly, the contents in the drive can get corrupted.

Best Methods to Repair Corrupted Files

1. Using System File Checker

System File Checker (sfc) is a built-in file checker utility in Windows, used to inspect all the essential Windows files on a computer. If the sfc finds a fault or corruption, it gets fixed immediately.

To use the system file checker,

  1. Press the “Windows + R” keys simultaneously to open “Run.”
  2. Type “cmd” in the box and press “CTRL+SHIFT+Enter” at the same time. This will open the Command Prompt as an Administrator.
  3. Type “sfc /scannow” in the command prompt window and press Enter.

The checker will inspect the entire system for corrupted Windows files and fix them if it finds any. Reboot your system once the scan is finished, and try to open the corrupted stuff you were unable to access earlier.

If the files are still not opening after the sfc scan, then move to the following method.

2. Using Check Disk

The check disk or “chkdsk” command is a terminal command used to check and repair a damaged or corrupted hard disk. Chkdsk also marks the corrupted sectors on a hard disk as “bad” and can be used to recover data from the disk.

To use chkdsk on your computer, do the following steps:

  1. Open Command Prompt as Administrator.
  2. Type “chkdsk c: /scan /forceofflinefix” and press Enter (you can change the volume name in the command for checking a different disk).

The command will run a disk check on volume C: as specified. It will scan and put the errors in a queue and fix them when the disk goes offline.

The disk check can also be done by another process, using the Windows Disk Error Checking tool. To use it,

  1. Go to “This PC” on Windows 10.
  2. Right-Click on the drive, you want to scan.
  3. Click on “Properties” and select the “Tools” tab from the top.
  4. Click on “Check” and then “Scan Drive.”

After the error scan and fix are complete, check whether the corrupted files are opening or not. If they aren’t, then move to the next step.

3. Converting the Files to another Format

Sometimes, file corruption can be caused due to using the wrong format. It can be solved by changing the format to a suitable one that can be used to open the item.

There are many free file converters available on the internet. Wondershare Uniconverter is one such converter that can convert images or videos from one format to the other.

NOTE: Always make a separate copy of the corrupted stuff before putting it in any converter so that if something goes wrong, you will still have the original data.

After converting the data to another format, check whether it works this time or not. If not, you need to repair the file corruption with an application to reaccess it.
