If you use a local Windows file system as the back-end storage for your self-hosted CentreStack installation, perhaps you've come across a problem of not being able to make copies of the back-end storage folders due to total file paths exceeding the Windows 260 character limit in Windows Explorer.
If you run into this problem, simply use Robocopy in a command prompt window to perform your copy operations. Robocopy is included with Windows (Vista and above), so you don't need to install anything. Here are the steps:
1-Open a command prompt window by pressing Windows Key + R. This will open the Windows Run box.
2-Type "cmd" and press the OK button.
3-Type "robocopy [SOURCE FOLDER PATH] [DESTINATION FOLDER PATH] /E"
4-Once you execute the command, the entire folder structure will be copied to the destination folder no matter how long the aggregate file paths are.
For more information about the robocopy command, type "robocopy /?" on the command prompt.
