The Mystery of the Reappearing “catalog.json” File in Temp Directories

For users and IT professionals alike, one of the most perplexing and persistent issues they may encounter is the reappearance of a file called “catalog.json” in various temporary directories on their systems. This seemingly innocuous file can crop up repeatedly, even after being deleted, leaving many scratching their heads as to its purpose and why it refuses to stay gone. In this article, we’ll delve into the potential reasons behind this phenomenon and explore some possible solutions.

What is the “catalog.json” File?

Before we investigate the reasons for its reappearance, it’s essential to understand what the “catalog.json” file is and its intended purpose. This file is typically associated with the Microsoft Store app on Windows 10 and 11 systems. It serves as a catalog or index of the applications available in the Microsoft Store, helping the app to retrieve and display information about the various software offerings.

The “catalog.json” file is usually located in the temporary folder of the current user’s profile, often under “C:\Users[Username]\AppData\Local\Temp” or a similar path. Its size can vary depending on the number of apps listed in the Microsoft Store catalog, but it’s generally not a large file.



The Importance of the “catalog.json” File

While the reappearing “catalog.json” file can be an annoyance, it’s important to note that the file serves a crucial purpose for the proper functioning of the Microsoft Store app. Deleting or disabling the file permanently may cause issues with the app’s ability to retrieve and display accurate information about available applications, updates, and other relevant data.

Why Does the “catalog.json” File Keep Reappearing?

Now that we know what the “catalog.json” file is, the next logical question is: why does it keep reappearing in the temporary directories, even after being deleted? There are several potential reasons for this behavior, and the root cause may vary depending on the specific system and configuration.

  1. Microsoft Store App Behavior

The primary reason for the reappearance of the “catalog.json” file is likely due to the behavior of the Microsoft Store app itself. When the app is opened or refreshed, it may attempt to download and update the catalog file from Microsoft’s servers. This process ensures that the app has the latest information about available applications, updates, and other relevant data.

Even if the “catalog.json” file is deleted from the temporary directory, the Microsoft Store app will likely recreate it during its next update or refresh cycle. This behavior is intentional and is designed to keep the app’s catalog up-to-date.

  1. System Restore Points and File Backups

Another potential reason for the “catalog.json” file’s reappearance could be related to system restore points or file backups. Windows creates restore points periodically or when certain events occur, such as installing a new application or driver. These restore points contain snapshots of system files, including the “catalog.json” file from the temporary directory.

If a system restore is performed or if Windows relies on a backed-up version of the “catalog.json” file during a repair process, the file may be restored to the temporary directory, causing it to reappear even after being deleted.

3.Third-Party Software Interference

In some cases, third-party software or utilities may be the culprit behind the reappearing “catalog.json” file. Certain applications or system optimizers may inadvertently recreate or restore the file during their operations, undoing any previous deletions.

Additionally, some antivirus or security software may flag the “catalog.json” file as potentially harmful and automatically restore it to its original location, causing it to reappear repeatedly.

  1. Synchronization Services

If you’re using cloud synchronization services like OneDrive or Dropbox, it’s possible that the “catalog.json” file is being synced across devices or backed up to the cloud. Even if you delete the file locally, the synchronization service may detect the change and restore the file from the cloud or another synced device, leading to its reappearance.

  1. Permissions and Ownership Issues

In rare cases, permissions or ownership issues with the “catalog.json” file or the temporary directory itself could be contributing to the file’s persistent reappearance. If the file is owned by a system account or has specific permissions that prevent its deletion, it may be automatically recreated by Windows or other system processes.

Potential Solutions and Workarounds

While the reappearance of the “catalog.json” file may be frustrating, there are several potential solutions and workarounds that you can try:

  1. Disable the Microsoft Store App

If you don’t use the Microsoft Store app and don’t need it running on your system, you can consider disabling or uninstalling it. This should prevent the app from attempting to update the “catalog.json” file and causing it to reappear.

To disable the Microsoft Store app, follow these steps:

  • Open the “Start” menu and search for “Turn Windows features on or off.”
  • Locate the “Microsoft Store” entry in the list and uncheck the box next to it.
  • Click “OK” to apply the changes and restart your computer if prompted.

Alternatively, you can uninstall the app entirely by following these steps:

  • Open the “Start” menu and search for “Add or remove programs.”
  • Locate the “Microsoft Store” entry in the list of installed programs.
  • Click on it and select “Uninstall.”
  • Follow the prompts to complete the uninstallation process.

Note: If you rely on the Microsoft Store for installing and updating applications, it’s generally recommended to avoid permanently deleting or disabling the “catalog.json” file. Instead, consider the workarounds and solutions outlined earlier, such as disabling the Microsoft Store app if you don’t use it or modifying file permissions to prevent the file from being recreated unnecessarily.

  1. Clear Temporary Files and Restart

Sometimes, simply clearing out all temporary files and restarting your system can resolve the issue of the reappearing “catalog.json” file. This approach can help reset any processes or services that may be responsible for recreating the file.

To clear temporary files, you can use the built-in Disk Cleanup utility in Windows:

  • Open the “Start” menu and search for “Disk Cleanup.”
  • Select your primary drive (usually C🙂 and click “OK.”
  • Check the box next to “Temporary files” and any other unnecessary file types you want to remove.
  • Click “OK” to start the cleanup process.

After the cleanup is complete, restart your computer and check if the “catalog.json” file has reappeared.

  1. Modify File Permissions

If permissions or ownership issues are causing the “catalog.json” file to reappear, you can try modifying the file’s permissions or taking ownership of it. This approach should be used with caution, as improper modifications can lead to system instability or other issues.

To modify the file’s permissions, follow these steps:

  • Navigate to the temporary directory where the “catalog.json” file is located (e.g., “C:\Users[Username]\AppData\Local\Temp”).
  • Right-click on the “catalog.json” file and select “Properties.”
  • Switch to the “Security” tab and click the “Edit” button.
  • Add your user account with “Full control” permissions or take ownership of the file.
  • Click “OK” to apply the changes.

After modifying the permissions, try deleting the “catalog.json” file again and see if it reappears.

  1. Disable System Restore and File Backups

If you suspect that system restore points or file backups are causing the “catalog.json” file to reappear, you can try disabling these features temporarily. However, be aware that disabling system restore and backups may leave your system more vulnerable to data loss in case of issues or system failures.

To disable system restore, follow these steps:

  • Open the “Start” menu and search for “Create a restore point.”
  • Click on “Create a restore point” in the Control Panel.
  • In the System Protection tab, select your primary drive (usually C:) and click “Configure.”
  • Select “Disable system protection” and click “OK.”

To disable file backups, you’ll need to consult the documentation or settings of your specific backup solution (e.g., OneDrive, Dropbox, or third-party backup software) and disable the backup or synchronization of temporary files or the “catalog.json” file specifically.

  1. Disable Antivirus or Security Software Temporarily

If you suspect that your antivirus or security software is interfering with the “catalog.json” file, you can try temporarily disabling or uninstalling the software to see if the issue persists. However, be aware that disabling security software may leave your system vulnerable to threats, so exercise caution and re-enable the software as soon as possible.

To disable your antivirus or security software, consult the documentation or settings of your specific software and look for an option to temporarily disable protection or real-time scanning.


The reappearance of the “catalog.json” file in temporary directories can be a persistent and frustrating issue for many users and IT professionals. While the file itself is generally harmless and serves a legitimate purpose for the Microsoft Store app, its persistent presence can be a nuisance.

By understanding potential reasons for this behavior, such as the Microsoft Store app update process, system restore points, third-party software interference, sync services, or permissions issues, you can better assess the cause and therefore find the correct solution
