Issue: How to fix error 0x800700CE: The filename or extension is too long?

Hello. I am unable to rename folders on my Windows 10 computer. I receive the error “0x800700CE: The filename or extension is too long.” Renaming files worked perfectly fine, what could be the issue?

Solved Answer

Windows is dependent on thousands of processes working in the background to keep it running smoothly. People can start experiencing bugs, crashes, freezes, and errors if something goes wrong. This can seriously disrupt the workflow and prevent people from completing important tasks. Some users have encountered an error “0x800700CE: The filename or extension is too long.”

This error seems to prevent users from renaming certain files, folders, or both. It can also make files and folders inaccessible, impossible to open or view because the error prevents it. It is unknown what could be causing such an issue, but some users reported that the behavior started after installing third-party security programs. If you have downloaded any antivirus tools recently, it is worth trying to uninstall them first, and seeing if that helps.

Some users said that simply running a File and Folder Troubleshooter has helped to fix the issue as well, so we included this step in our guide. Unfortunately, not all people were so lucky. Some said that they tried everything and nothing worked. The 0x800700CE error only stopped appearing after they performed a clean install. So keep in mind that this might be something you have to do if the issue will persist.

Troubleshooting can be a lengthy process so you can try running a maintenance tool like ReimageMac Washing Machine X9 that can fix most system errors, BSODs,[1] corrupted files, registry[2] issues, and so on. The software can also clear cookies and cache[3] automatically, so you would not have to worry about browser activity tracking. Otherwise, proceed with the steps below if you are ready to begin the process that could fix the “0x800700CE: The filename or extension is too long” error.
