How to Fix Destination Path Too Long Error in Windows 10

With the imminent end of life support for Windows Server 2008 and Windows 7, file server migrations maybe part of your upgrade plan to Windows Server 2019 or Windows 10.

However, file server migrations with file names and paths that are too long will still fail.  Moreover, the Storage Migration Service will fail to the Azure cloud.


And note, the new Windows 2019/Windows 10 Path Too Long setting is not fully integrated into the entire system, so CMD.exe and Windows Explorer will not copy paths that are too long. 


For Windows 10 users that encounter the "Destination Path Too Long Error" while attempting to  copying, delete or move files from a source location to a separate location or drive. 

Windows Operating System has a MAX PATH variable that determines a limit to the number of characters applicable in the path of a file which is 260 in normal circumstances. When you make an effort to copy a file from the location, the destination path calculated is the sum of characters existing in the source path and filename. And as this number surpasses 260 you confront with "Destination Path Too Long Error", or many others.
