Step 1: Right-click on the target file and select (Properties).
Step 2: In the pop-up window, select the (Security) tab.
Step 3: In the (Group or user names) list, select the target user name. Then click the (Edit) button.

Step 5: Click (OK) to save the modified operation. Then you can open, modify or delete the file.
3. Check the program or file path
If the path of the program or file is incorrect, it will also result in the inability to run the program or open the file. You can check the path of the file. Specific steps are as follows.
To view the location of the target file, right-click on the file and select (Properties) > (General).
Kind tips If a shortcut is unable to access a file, it could mean that the file’s path has been changed. In such a scenario, you can fix the issue by navigating to the program or file’s location and re-creating the shortcut.

If you have anti-virus software installed on your computer, you can try to temporarily disable the anti-virus software. In some cases, antivirus software blocks access to files. You can try the following steps to disable antivirus software.

Step 2: In the opened (System Configuration) window, select the (Startup) tab. Then click (Open Task Manager).
Step 3: In the pop-up window, select antivirus software. Next, right-click and select the (Disable) button. You can then try to run the program or open the file.
