 C:\> robocopy /E /COPYALL C:\Program Files\PROGRAM_FOLDER N:\Program_Files\PROGRAM_FOLDER

robocopy should be used to matching SOURCE_FOLDER to DESTINATION_FOLDER, FOLDER to FOLDER. Usually, DESTINATION FOLDER might not be existing before execute command. And make a link for substituting original folder.

 C:\> ren PROGRAM_FOLDER PROGRAM_FOLDER_   
 C:\> mklink /J PROGRAM_FOLDER N:\Program_Files\PROGRAM_FOLDER

Login credientials forgotten

Attached (or extended) storage make sometimes permission issues. For better performance, caches and temporary files are forced to locate attached one. However, caching files can have conflict with permission problem.

Symptom: Login credentials saved are not recognized and requires fresh new authentication. – login credentials are not stored as cache.
