Understanding FDL Issues

Typical FDL Opening Challenges

Corel WordPerfect X8 Removed

If you attempt to load your FDL file, you experience a message such as "Can't Open FDL Files". Generally, this is experienced in %%os%% because Corel WordPerfect X8 isn't installed on your PC. The typical path of opening your FDL with a double-click won't work because %%os%% cannot make the program connection.

Tip: If you have another software that you know opens FDL files, you can select it by hitting the "Show Apps" button.

Outdated Corel WordPerfect X8

In some cases, you might have a newer (or older) version of a Corel Paradox Secondary Index file that is unsupported by your installed application version. If you've got the wrong version of Corel WordPerfect X8 installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

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

Conclusion: The majority of FDL file opening issues are due to not having the correct Corel WordPerfect X8 version installed.

Associated Difficulties Loading FDL Files

In the majority of cases, installing the right version of Corel WordPerfect X8 will resolve your issue. There can be external issues inside of %%os%% that are causing these errors when opening FDLs. These issues include:

• Something has caused file corruption of your FDL
• Your FDL is infected with malware
