What is Thumbs.db?

Thumbs.db is a hidden system file that is created by Windows in each folder that contains images or videos. It stores small thumbnail versions of the images or videos in that folder, allowing for quick and easy previewing of the content. These thumbnails are displayed when you view the folder in Windows Explorer or any other file manager.

Thumbs.db is created automatically by Windows and is not meant to be opened or modified by users. It is a database file that stores information about the images or videos in the folder, such as their location, size, and other metadata. This allows Windows to quickly generate and display the thumbnails without having to read and process the original files every time.

Common Errors with Thumbs.db

While Thumbs.db serves a useful purpose, it can sometimes cause errors and issues that can be frustrating for users. Some of the common errors associated with Thumbs.db include:

  1. Access Denied: This error occurs when Windows is unable to access or modify the Thumbs.db file. It can happen if the file is locked by another process or if the user does not have the necessary permissions to access the file.
  2. File In Use: This error occurs when a file that is referenced in the Thumbs.db file is currently in use by another program. Windows cannot update the Thumbs.db file until the file is no longer in use.
  3. Corrupted Thumbs.db: In some cases, the Thumbs.db file itself can become corrupted, leading to errors when trying to view or access the thumbnails.

How to Fix Thumbs.db Errors

Fixing Thumbs.db errors can be relatively simple, and there are a few methods you can try:

Method 1: Delete Thumbs.db

The easiest way to fix Thumbs.db errors is to delete the file. Since Thumbs.db is automatically generated by Windows, deleting it will not cause any issues. Windows will recreate the file when needed.

To delete Thumbs.db, follow these steps:

  1. Open Windows Explorer and navigate to the folder where the Thumbs.db file is located.
  2. Click on the “View” tab in the ribbon at the top of the window.
  3. In the “Show/hide” section, check the box next to “Hidden items” to show hidden files and folders.
  4. Locate the Thumbs.db file in the folder.
  5. Right-click on the Thumbs.db file and select “Delete” from the context menu.

After deleting the Thumbs.db file, you may need to refresh the folder or restart Windows Explorer for the changes to take effect.

Method 2: Disable Thumbnail Previews

If you frequently encounter Thumbs.db errors or simply prefer not to have thumbnail previews in your folders, you can disable the feature altogether. Disabling thumbnail previews will prevent Windows from creating Thumbs.db files in the folders.

To disable thumbnail previews, follow these steps:

  1. Open Windows Explorer and click on the “View” tab in the ribbon at the top of the window.
  2. In the “Show/hide” section, click on the “Options” button.
  3. In the “Folder Options” window, click on the “View” tab.
  4. Under the “Advanced settings” section, check the box next to “Always show icons, never thumbnails”.
  5. Click “Apply” and then “OK” to save the changes.

After disabling thumbnail previews, Windows will no longer generate Thumbs.db files in the folders.

Method 3: Scan for Viruses or Malware

In some cases, Thumbs.db errors can be caused by viruses or malware on your system. It is always a good idea to scan your computer for any potential threats using a reliable antivirus or antimalware software.

We recommend using Malwarebytes Free to scan your system for viruses and malware. Malwarebytes is a trusted and effective software that can help detect and remove any malicious programs that may be causing Thumbs.db errors.

Summary

Thumbs.db is a file generated by Windows to store thumbnail images of files in a folder. While it can be useful for quick previews, Thumbs.db can also cause errors and issues. Common errors include “Access Denied,” “File In Use,” and corrupted Thumbs.db files. To fix these errors, you can delete the Thumbs.db file, disable thumbnail previews, or scan for viruses and malware. By following these methods, you can resolve Thumbs.db errors and improve your overall Windows experience.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
