Fix Error 0x800700ce, the Filename or Extension Is Too Long

Encountering Error 0x800700ce: The Filename or Extension Is Too Long can be frustrating, especially when you’re trying to copy, move, or delete files in Windows. This error usually appears when the full path of a file—including folder names and the file name itself—exceeds the maximum path length limit of 260 characters set by Windows. Fortunately, there are several effective solutions to overcome this issue, from enabling long path support to renaming or relocating files. In this guide, we’ll walk you through step-by-step methods to fix this error and make file management smoother.

2. Rename Files or Folders

• Shorten the file names or folder names in the path.
• Example: Change C:\Users\JohnDoe\Documents\Projects\Work\Reports\2025\January\FinalVersion\Drafts\VeryLongFileNameExample.txt
  to
  C:\Users\JohnDoe\Docs\Report.txt.

3. Move Files to a Root Directory

• Cut and paste files to a folder closer to the root (like C:\Temp) to shorten the overall path.

4. Use Command Prompt (Robust File Operations)

If File Explorer fails to delete/move the file:

1. Open Command Prompt (Admin).
2. Use the robocopy command to move or copy files: robocopy "C:\SourceFolder" "C:\DestFolder" /E /COPYALL /MOVE

Or use the del command for deleting:

del "\\?\C:\Very\Long\Path\to\File.txt"

The \\?\ prefix allows bypassing the MAX_PATH limit.

• Extract it there.
