PC Refresh service – your computer renewed

Published by:

These days a PC that is a few years old will most likely still be quite capable of useful work, but might be held-back by particular components or original specification that can be easily updated. This is especially true for work-horse systems used for web access, database or document processing – rather than high end media work or gaming systems which do generally benefit from the latest processors & technology.

An internal spring clean with battery or main drive replacement or memory boost might be all that’s required to rejuvenate your system for a few more productive years at a fraction of the cost to buy new.

Windows Robocopy command common usage issues problems & gotchas

Published by:

Enclosing the source or destination in double quotes allows the use of paths with spaces in the folder names but DO NOT end with a trailing backslash ‘\’ as this will be interpreted as an escape character.

When using the task scheduler to run a robocopy command script be aware that using the account credentials of the logged-in user may be necessary for access to network drives referred to by the command. An administrator account may not have the necessary permissions.

Syntax
      ROBOCOPY Source_folder Destination_folder [files_to_copy] [options]

      ROBOCOPY "M:\" "X:Destination Folder\" DON'T USE EITHER OF THESE

      ROBOCOPY M:\ "X:Destination Folder" THIS WORKS
