Method 3: Enable the Long Path Support in Registry Editor
If you are using Windows 10 1607 or the later version, you can enable the Long Path Support via Registry Editor to solve the issue. To be specific, you can disable the MAX_PATH limit in Windows. Before modifying Registry keys, you’d better back up the key for accidents.
Here is a simple guide:
1. Press Win + R to open Run.
2. Input regedit and press Enter to open Registry Editor.
3. Navigate to the following path:
Computer > HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > FileSystem.
4. Find LongPathsEnabled and double-click on it.
5. Modify the value data to 1.
6. Click OK to keep the change.
Then, you can quit Registry Editor and operate the file or folder to see whether you can copy or move them successfully.
Method 4: Use the xcopy Command
When we search for this issue on the internet, we find that some users reflect that they solve it using the xcopy command in an elevated command prompt. This method is worth trying.
If you don’t know how to do this work, you can follow this guide:
1. Click Start and search for cmd.
2. Right-click the first result and select Run as Administrator.
3. Copy and paste the following command line to the elevated Command Prompt:
xcopy *path to source files* *path to destination* /O /X /E /H /K
Here, *path to source files* and *path to destination* are simply placeholders for the exact paths. You need to replace the placeholders with the real locations before hitting Enter.
4. Press Enter.
We believe that Destination Path Too Long should be solved after using the above methods.
