How to put comments on Batch File, VBA, Java, PowerShell and Python

Comment on any programming language is extremely helpful.
It will ease the debugging process.
And it will make the code or the function easy to read or remember on what the piece of code or function is doing.
If the program runs for years and a new OS is release and the program runs into compatibility issues.
And the next programmer who comes along and who knows it will be you again.
If the program has comments then it will be easy to read the source code.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

gci d:\WorkFolde…
