If you encounter an "Access is denied" error when trying to extract a downloaded zip file, it typically means that your system does not have the necessary permissions to perform the operation.
Here are some steps you can try to resolve the issue:
Run the extraction process as an administrator : Right-click on the zip file, and select "Extract all" from the context menu. Then, when prompted for the extraction destination, click "Browse" and choose a location where you have write permissions, such as the Desktop or a folder in your user directory. Before clicking "Extract", check the box that says "Show extracted files when complete".
Check file permissions: Ensure that you have the necessary permissions to access and modify the destination folder (in this case, the "Downloads" folder). Right-click on the folder, select "Properties", and navigate to the "Security" tab to review the permissions. Make sure your user account has "Full control" or "Modify" permissions.
Temporarily disable antivirus or security software: Sometimes, security software can interfere with file extraction processes. Try temporarily disabling any antivirus or security software you have installed and then attempt the extraction again.
Use a different extraction tool: If the built-in Windows extraction tool continues to give you trouble, try using a third-party extraction tool such as 7-Zip or WinRAR. Don't change location of files: During extracting those zip files there may be some default location maybe in c drive so extract there don't extract in downloads. I HOPE THIS HELPS YOU
If none of these steps resolve the issue, you may need to seek further assistance from technical support or forums specific to your operating system and file extraction software.
