Some Windows users report that after downloading zipped folders, trying to access it later is impossible. They get a message saying that the compressed folder is invalid. So why does this happen? Can it be fixed? Here are our answers.

Why is my zip file saying invalid?

Some of the most common reasons for your zip file bringing up an invalid error message include:

Damaged hard drive – If there are bad sectors on your hard drive, this may cause errors when creating or opening files. Outdated OS – If you’re running an older version of Windows, there’s a good chance you don’t have all the latest updates installed on your computer. Corrupt file – The file may have been downloaded from a bad website or a website that specializes in malware. Extension mismatch – Some applications will not open zip files unless they have been added as an extension on your computer.  Insufficient storage – If there isn’t enough disk space available on your computer when you try to extract all your files from a compressed folder, things can go wrong pretty fast. Outdated software – If you haven’t updated your compression software in a while, it may fail to open or extract files because of compatibility issues. Viruses/malware – Sometimes, there are bugs in your system which prevent them from correctly extracting certain types of files. Insufficient permissions – You may get access to the compressed (zipped) folder is denied message if you do not have sufficient privileges to access the folder where your zip file is stored. 

How do I fix a compressed zipped folder invalid?

A few workarounds that could help you get out of this rubble include:

Ensure you’re running the latest version of your file compression tool. Check the permissions on your files and folders to ensure they are correct. Also, ensure you’re using an administrator account, as local accounts have some restrictions. Make sure that you have enough space on your computer’s hard drive for the file to unzip. Change the file extension. For instance, if you had a .zip file, rename it to .rar and try opening it again. Try to repair corrupt files using the CHKDSK utility. Redownload the files using a different browser.  Run Windows Update to install the latest updates. These updates fix bugs and security holes in Windows.

1. Restart File Explorer

2. Run the DISM and SFC scans

3. Scan for viruses

4. Reinstall the compression software

If you don’t have the same version of the software installed on your computer as the person who sent you the file, it might not work properly. In some cases, an update that caused the problem with your compressed folder may have been released. However, reinstalling the software from scratch can often fix this issue and make your compressed folders work again. SPONSORED

5. Try a different file compression software

If reinstalling does not work, you may need to try using another compression program instead of the one you have. This might seem overkill since most people only use one program to compress their files. However, sometimes there are issues with certain programs that can cause this type of problem with your compressed folders. If downloading another program seems over the top, try online compression tools. You can also attempt to repair the corrupt zipped folders and then try opening them again. Aside from compressed folder issues, you may be interested in password-protecting your zipped folders to prevent unauthorized access.
