Summary

Unable to clone the repository in Windows and getting the below error:

error invalid path - filename
fatal unable to checkout working tree

Environment

• Windows
  
  

Cause

Windows reserves certain file names. So when it tries to create a file that uses a reserved base name or uses special characters it will fail.

Please refer to the Naming a file Windows documentation:

Do not use the following reserved names for the name of a file:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed immediately by an extension; for example, NUL.txt is not recommended

Solution

• Check the git repository you are trying to clone and analyze if there are any file names consisting of the Windows Reserved Characters.
• Rename the file by removing all the reserved characters in the remote git repository. 
• Try cloning the repository again and it should clone without any issues.
