robocopy D:\ E:\ /Copyall /S /E /dcopy:T /b /R:3 /W:1 /Log:C:\robocopy-log3.txt /NP

This command is using the Robocopy (Robust File Copy) utility to copy all files and directories from the source directory "D:" to the destination directory "E:" while preserving all file attributes and timestamps. Here's a breakdown of the different options used in this command:

robocopy: This is the command to invoke the Robocopy utility.

D:\: This is the source directory from which files and directories will be copied.

E:\: This is the destination directory where files and directories will be copied.

/Copyall: This option copies all file information, including data, attributes, timestamps, security, and owner information.

/S: This option copies subdirectories, but not empty ones.

/E: This option copies subdirectories, including empty ones.

/dcopy:T: This option copies the directory timestamps, but not the file timestamps.

/b: This option copies files in Backup mode. This means that Robocopy will bypass file security restrictions and copy files that would otherwise be skipped due to lack of permissions.

/R:3: This option sets the number of times Robocopy will retry a failed copy operation. In this case, Robocopy will retry three times before giving up.

/W:1: This option sets the time, in seconds, that Robocopy will wait between retries.

/Log:C:\robocopy-log2.txt: This option specifies the path and filename of the log file that will be created to track the progress and results of the copy operation.

/NP: This option prevents the progress of the copy operation from being displayed in the command prompt. This is useful when running the command in a batch file or script.
