CDX Troubleshooting

Troubles Opening CDX Files

Microsoft Visual FoxPro Not Present

You encounter an error message such as "%%os%% Can't Open CDX Files" when trying to open your CDX. If this is the case, it's usually due to the fact that you do not have Microsoft Visual FoxPro for %%os%% installed on your computer. The OS won't know what to do with your CDX file, so double-clicking to load the file doesn't work.

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

Outdated Microsoft Visual FoxPro

In other instances, your Compound Index File file version may not be supported by your version of Microsoft Visual FoxPro. You will need to download a newer version of Microsoft Visual FoxPro if you don't have the right version. This problem is predominately due to having a Compound Index File file version that was created by a newer version of Microsoft Visual FoxPro than what you have installed on your PC.

Tip: Right-clicking on your CDX, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Conclusion: The majority of CDX file opening issues are due to not having the correct Microsoft Visual FoxPro version installed.

More Causes of Problems Opening CDXs

Assuming you have the right Microsoft Visual FoxPro version installed, other problems can prevent you from opening CDX files. Other CDX opening errors can be created by other system problems inside of %%os%%. Issues that aren't software-related:

• CDX file type Registry entries are wrong
• Corruption of the CDX file description inside the Registry
• Corrupt install of Microsoft Visual FoxPro or other CDX-related program
• Your CDX file is corrupted (issues with your Compound Index File file itself)
• Your CDX has adversely impacted by malware
• Hardware related to CDXs has device driver corruption
• Your PC doesn’t have enough available resources to open the Compound Index File file
