#
# This script:
#  1) Compacts Microsoft Outlook personal storage table (PST) data files.
#  2) Backs up PST data files into a date and time stamped folder.
#  3) Launches multiple applications.
#
# To set this script up to launch every time you log into Windows:
#  1) Create a Windows shortcut for this script with a target like the following (not including the # sign):
#     powershell.exe -command "& 'C:\Users\Rick\Documents\CloudStation\Rick Startup.ps1'
#  2) In "Run", type "shell:startup" to open the startup folder with shortcuts for apps which should open after logging into Windows.
#  3) Put the newly created shortcut for this script into the startup folder.
#  4) Are there any other shortcuts in the startup folder? Consider deleting the other shortcuts and having this script open those
#     application instead to avoid a situation where the launch of other apps could interfere with the execution of the AutoIT3 (au3)
#     script. To do this, copy the target for each shortcut in the startup folder and paste it into this script preceded by a & character
#     so that this script executes the shortcut, then delete the shortcut from the startup folder.
#  
# Potential future enhancements for this Powershell script:
#  1) I should rarely need to monitor disk space usage on the destination drive since I am backing up files to a Synology NAS that has
#     a huge amount of free disk space. However, if disk space usage becomes a problem, then I could enhance this script to do one of the
#     following:
#      a) Delete backup files older than X days.
#      b) Delete files with a certain day of the month in the backup name so that a sampling of old and new backup files are retained.
#      c) Do one of the above only when disk space is less than X GB available.
#  2) If I get into a situation where I am away from home with my laptop for multiple days, then I could enhance the script to back up
#     files to a USB drive when the NAS drive isn't detected.

# Call AutoIT script to compact all Outlook PST files, waiting for the script to complete before moving on to the next step
# in this PowerShell script. The code for the AutoIT script is here: https://gist.github.com/rickupton/16f9a7b445a668c70c61

# Launch multiple applications.
#  * AFTER au3 script runs so that AutoIT3 (au3) script doesn't run into problems due to other apps being open.
#  * BEFORE the lengthy copying of Outlook PST files begins so that other apps may be used during the PST file copy process.
