• Software compatibility and conflicts: Version incompatibilities or software crashes cause errors during file saving.

• Malware attacks: Malware can modify, delete, or encrypt files, leading to corruption.

For these scenarios, a corrupted file checker is required. Read the following section to understand what this checker is.

The corrupted file checker is a tool designed to scan computer systems, identify damaged, missing, or tampered files, and try fixing them. It can not only detect corrupted files but also detect disk errors. Such tools ensure data integrity and maintain stable system operation.

Here are its specific functions:

• Read internal file structure: Verify file headers and data integrity.

• Mark corrupted files: Identify files that cannot be opened, contain garbled data, or are incomplete.

• Detect disk errors: Scan drive structures to discover existing and potential disk errors.

• Attempt repair: Try to reconstruct the file structure and recover usable content.

This section teaches you how to check for corrupted files Windows 10/11 with 4 reliable corrupted file testers.

1. Backup File Recovery Tool

The first tool, backup file recovery, is a specialized corrupted file checker. Strictly speaking,it is not technically a file checker. It doesn’t diagnose file corruption or disk errors but is instead designed to recover your corrupted files.

Backups can generally be categorized into two types: local backups and cloud backups.

• Local backup recovery: Local backups are stored on devices such as external hard drives or USB drives. To recover corrupted files, simply locate the backup copy and restore them to the original location.

• Cloud backup recovery: Cloud backups are stored on services like OneDrive, Google Drive, or Dropbox. If files get corrupted, you can restore a previous version or download a intact copy from the cloud backup.

If you don’t have a backup, don’t worry, proceed with the next tool.

2. System File Repair Checker

Windows includes a dedicated tool for repairing system files called System File Checker (SFC). This tool scans for corrupted system files and automatically repairs them using built-in recovery resources.

SFC relies on the Windows component store. Run DISM first can ensure the integrity of the underlying component store. This allows SFC to successfully use it to repair corrupted system files.

Here is how to run DISM and SFC to check for corrupted files:

Step 1. Type Command Prompt in the Windows search box, right-click the best match, and choose Run as administrator.

Step 2. Type DISM /Online /Cleanup-Image /RestoreHealth in the window and press Enter.

Step 3. When DISM process ends, continue typing SFC /scannow and press Enter.

Once the scan is complete, the scan results will be shown. Perform relevant operations based on the results.

3. Disk Diagnostic Checker

While built-in tools like SFC are effective at diagnosing and repairing files, some users, recognizing that disk errors can also cause file corruption, may prefer comprehensive tools that combine disk monitoring, system repair, and performance optimization capabilities.

Advanced SystemCare is one such tool. As a reliable corrupted file checker, it provides a feature called Disk Doctor to help detect and fix hidden disk errors.
