Part 1. Causes of Compressed Zip Folder Error

If you are denied access from a ZIP folder, or Windows 11/10/8.1/8/7/XP declares the folder to be invalid, it’s tough to pinpoint the exact cause of the problems. However, since these are common issues, we know that they can be caused by the factors listed below.

  • Presence of malware in the zipped archive.
  • The file wasn’t downloaded correctly or is corrupt.
  • The tool used for compression or decompression has errors.
  • You lack sufficient permissions to access the archive.
  • You didn’t set your %TEMP% variable properly.
  • Damaged ZIP archive header.
  • A mismatch is found during the CRC (cyclic redundancy check) checksum.
  • Part 2. How to Fix Compressed Zip Folder Error in Windows

    Knowing the causes makes it easier to troubleshoot and fix the compressed ZIP folder error. In this section, we’ll explore the best ways to fix the compress folder access denied error as well as when the ZIP folder is invalid.

    1Fix Compressed Folder Access Denied Error

    The compressed folder access denied error is quite clear – your user account does not have the required permissions to access or modify the ZIP folder. Hence, you’ve been forbidden from opening the archive. Here, you’ll learn how to gain access and in turn, get rid of the access denied error.

    Method 1: Fix the TEMP environment variable

    To begin troubleshooting the compressed folder access denied error, the first thing to do is to repair the TEMP environment variable. Here’s how to do it:

  • Right-click on This PC and select Properties.
  • Select Advanced System Settings from the left-hand panel.
  • Click on Environment Variables.
  • Select TEMP in the User Variables, then click on Edit. (If there’s no TEMP variable, click on the New button and create one.)
  • set TEMP environment variable

  • Set the variable value as:

  • Hit the OK button, then restart your computer or log out and back into your user account, and check if you can open the compressed folder normally.
  • If this doesn't help, then it may mean that you don’t have sufficient permissions for the %TEMP% folder, check the next method.

    Method 2: Request Permission for the %TEMP% Folder

    Having fixed the TEMP environment variable, you now have to ensure that your user account has permissions to modify the TEMP folder, follow the steps below.

  • Launch File Explorer.
  • In the address bar, type in %temp% and hit ENTER.
  • Right-click on an empty area in the File Explorer window and select Properties.
  • Navigate to the Security tab and click on Edit.
  • Look for Users on the list. If it’s missing, add it.
  • Edit the right of Users and give it permission to Modify, click on OK to save.
  • set permission for TEMP folder

    2Fix Compressed Zip folder Is Invalid Error

    If you see this specific error, then you can be sure that the issue is not from your user account, computer, or zip folder settings. The error clearly means that the zip folder itself is corrupted, or the tool used for compressing it malfunctioned. Use the following methods to repair your corrupt ZIP folder.

    Method 1: Repair Corrupt Zip Folder with WinRAR

    Step1: Download WinRAR on your PC and launch it.

    Step2: Browse for the corrupted ZIP file and right-click on it. Select the Repair or Repair archive option from the context menu.

    Step3: Choose the directory in which you want to save the repaired file. Ensure that you mark the Treat the corrupt archive as ZIP checkbox and then click on the OK button.

    NOTE: Following the repair, the output file will be saved in the location you chose in step 3. This folder will be named _rebuilt.zip.

    Method 2: Repair Zip Folder with Command Prompt

    WinZip has a command line support add-on that enables you to fix corrupt zipped folders. After setting it up, follow the steps below to repair your corrupt ZIP folder using Command Prompt.

    Step1: Press the Windows + R combination to open the Run dialog box.

    Step2: In the Run dialog box, type in cmd and run command prompt as administrator.

    Step3: Use the cd command to navigate to the directory of the faulty ZIP folder. i.e., cd path/to/the/folder.

    Step4: Run the following command: “C:\Program Files\WinZip\wzzip” -yf zipfile.zip. (replace zipfile.zip with the name of your zip file.)
