What Does 0x800700CE Mean?

The filename or extension is too long. The full path exceeds the maximum length (260 characters by default).

Real-World Causes

  1. 1Deeply nested folder structure creating long paths
  2. 2Long file names combined with deep directory paths
  3. 3Extracted archive contains paths longer than Windows allows
  4. 4Cloud sync tools creating deeply nested folder structures

Symptoms

  • Cannot create, copy, or move files with long paths
  • File extraction from archives fails
  • Sync tools report errors on specific files
  • Cannot delete deeply nested folders

DIY Fix

Beginner-friendly steps you can try at home

  1. 1Shorten folder names in the path
  2. 2Move the parent folder closer to the root (e.g., C:\)
  3. 3Enable long paths: Settings > System > About > Advanced system settings or Group Policy
  4. 4Use 7-Zip to extract archives with long paths (it handles them better)

Advanced Fix

For experienced users and IT professionals

  1. 1Enable Win32 long paths via Group Policy: Computer Configuration > Administrative Templates > System > Filesystem > Enable Win32 long paths
  2. 2Use '\\?\' prefix in commands to bypass the 260-character limit
  3. 3Use robocopy (which supports long paths) to copy files

Frequently Asked Questions

What is the maximum path length in Windows?
The legacy limit is 260 characters (MAX_PATH). Windows 10 version 1607 and later can support paths up to approximately 32,767 characters when long path support is enabled via Group Policy or the registry. Not all applications support long paths yet.
