Y01 File Complications

Troubles Opening Y01 Files

Corel WordPerfect X8 is Not Installed

You attempt to load your Y01 file and get an error such as "%%os%% Can't Open The Y01 File Extension". If so, it typically means that you don't have Corel WordPerfect X8 installed for %%os%%. Your operating system cannot associate your Y01 with Corel WordPerfect X8, so double-clicking the file won't work.

Tip: If you know of another program that can open your Y01 file, you can try opening it by selecting the application from the programs listed.

Corel WordPerfect X8 Requires Update

Sometimes your installed version of Corel WordPerfect X8 won't support your Corel Paradox Secondary Index file. Download the latest Corel WordPerfect X8 version from the Corel website to ensure you have the correct one installed. Your Corel Paradox Secondary Index file was probably created by a newer release of Corel WordPerfect X8 than what's currently installed your computer.

Tip: You can sometimes get hints about the right program version by right-clicking on the Y01 file, selecting "Properties", and looking at the version information.

Primarily, problems experienced when opening Y01 files are due to having the incorrect version of Corel WordPerfect X8 installed on your computer.

Other Y01 File Issues

You can still experience errors opening Y01 files even with the latest version of Corel WordPerfect X8 installed on your PC. There can be external issues inside of %%os%% that are causing these errors when opening Y01s. Other contributing causes:

• Invalid Y01 file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Unintentional removal of the description of the Y01 file inside the Windows Registry
• Corrupt install of Corel WordPerfect X8 or other Y01-related program
• Your Y01 file is corrupted (issues with your Corel Paradox Secondary Index file itself)
• Your Y01 is infected with malware
• Hardware associated with Y01 has outdated drivers
• Windows has inadequate resources to open your Corel Paradox Secondary Index file
