Postup řešení

1. 1 First, check the file extension. Right-click the file and select Properties. Look at the 'Type of file' field. If the extension doesn't match the actual file content, it might be corrupted or misnamed. For example, a file named 'report.pdf' might actually be a text file. Try opening it with a different program that matches the actual content.
2. 2 If the file is a system file or a program file, try running the System File Checker. Press Win+R, type 'sfc /scannow', and press Enter. This will scan and repair corrupted system files that might be causing the error.
3. 3 If the error occurs when opening a specific file type, reset the file association. Go to Settings → Apps → Default apps. Scroll down and click 'Choose defaults by file type'. Find the file extension (e.g., .txt) and select the correct app. This ensures that the right program opens the file.
4. 4 If the file is from an external source (like a download), it might be corrupted. Download the file again from the original source. If it's a document, try opening it in a different application like Notepad or WordPad to see if it's actually a text file.
5. 5 If the error occurs in a specific application, try reinstalling that application. Go to Settings → Apps → Installed apps, find the app, and click Uninstall. Then download the latest version from the official website and install it. This replaces any corrupted program files.
