function Position-ExplorerWindow { <# .SYNOPSIS Opens, resizes, and arranges multiple Explorer Windows at specified paths in a grid fashion to fit a screen, or multiple screens. .DESCRIPTION This script / module has the ability to quickly open multiple Explorer Windows at specified paths in an grid, arranging them to fit a screen, or multiple screens (no limit, really), in a predictable and orderly fashion. All you have to do is to add the folders into the script config, and run the script, and you get a grid of Explorer windows. This is most useful when working with half a dozen or more folders simultaneously, because it saves time and effort rearranging and fitting Explorer Windows into a nice and orderly fashion, so that they can be easily accessed. Background: An Explorer window cannot be opened at a specified coordinate on the screen through its command line. Because the author could not find any working solution that could conveniently open multiple Explorer windows in specified folders arranged in a predictable and orderly fashion on the screen, there had to be a tool that could do this. .PARAMETER Paths # Defines the paths (folders) the Explorer windows should show. # Enter one path per line. Edit between the single-quotes. # E.g. $Paths = ' # D:\My Data Folder\Data1 # D:\My Data Folder\Data2 # D:\My Data Folder\Data3 # D:\My Data Folder\Data4 # \\MYSERVER\public # \\192.168.0.1\\share # ' .PARAMETER ModeEasy # Simple Mode. In this mode, most defaults are used. # If you hate configurations, simply use this with -Paths .PARAMETER DestinationScreenWidth # Resolution of the Destination Screen (think of this as block of pixels, and not necesarily a Monitor's resolution) where the Explorer windows will reside. # For Single-Monitor setups, in most cases should match your Monitor's resolution. # For Multi-Monitor setups, you may also think of this a pooling of a block of pixels spanning your screen(s). You may use 3840 x 1080 to pool multiple monitor pixels together, or use 640 x 480 to select a smaller pool .PARAMETER DestinationScreenHeight # Resolution of the Destination Screen (think of this as block of pixels, and not necesarily a Monitor's resolution) where the Explorer windows will reside. # For Single-Monitor setups, in most cases should match your Monitor's resolution. # For Multi-Monitor setups, you may also think of this a pooling of a block of pixels spanning your screen(s). You may use 3840 x 1080 to pool multiple monitor pixels together, or use 640 x 480 to select a smaller pool .PARAMETER DestinationMonitor # Physical position of the Destination Monitor where the Explorer windows will open # NOTE: # This is ignored if you have only 1 monitor. # Possible values: 'M', L', 'R', 'T', 'B' # E.g. 'M' - Destination Monitor is the Main Monitor # E.g. 'L' - Destination Monitor is to the left of the Main Monitor # E.g. 'R' - Destination Monitor is to the right of the Main Monitor # E.g. 'T' - Destination Monitor is to the top of the Main Monitor # E.g. 'B' - Destination Monitor is to the bottom of the Main Monitor # Default: 'M' .PARAMETER Rows # Define the number of rows of Explorer instances # E.g. 4 - a maximum of four explorer instances will be stacked vertically in a column. The 5th-8th windows will be stacked on the next column to the right of the previous column. And so on. # Default: 4 .PARAMETER Cols # Define the number of columns of Explorer instances # If a value greater than 1 is specified, columns of x windows will stack horizontally (where x is a defined in $Rows) # E.g. A value of 2 means that 2 columns of x explorer instances will be stacked horizontally # Default: 2 .PARAMETER OffsetLeft # How many pixels left/right the Explorer instances should be shifted from the Top-Left Corner(0,0) of the Destination Monitor. Useful in the case of multiple-monitor setups. # Best to be left as default (left-most of Destination screen) # E.g. Single Monitor setups: # 0 positions the windows on the Main monitor, starting from its leftmost edge # E.g. Multi-Monitor setups: # 0 positions the windows on the Destination monitor, starting from its leftmost edge. # x the windows the windows on the Destination Monitor, x pixels right of its leftmost edge. # -x positions the windows on the Destination Monitor, x pixels left of its leftmost edge. # Default: 0 .PARAMETER OffsetTop # How many pixels up/down the Explorer instances should be shifted from the Top-Left Corner(0,0) of the Destination Monitor. Useful in the case of multiple-monitor setups. # Best to be left as default (The very top of destination screen) # E.g. Single Monitor setups: # 0 positions the windows on the Main monitor, starting from its topmost edge # E.g. Multi-Monitor setups: # 0 positions the windows on the Destination monitor, starting from its topmost edge. # y the windows the windows on the Destination Monitor, x pixels down of its topmost edge. # -y positions the windows on the Destination Monitor, x pixels up of its topmost edge. # Default: 0 .PARAMETER Flow # Arrangement of Explorer Windows # Whether windows should flow left-to-right, or top-down fashion # 'X' - Left-to-Right fashion. # --------- # | 1 | 2 | # --------- # | 3 | 4 | # --------- # 'Y' - Top-Down fashion # --------- # | 1 | 3 | # --------- # | 2 | 4 | # --------- # Default: 'Y' .PARAMETER DebugLevel # Debug level # 0 - Off # 1 - On .EXAMPLE Example 1a: This opens 4 windows: all 4 windows stacked vertically, occupying a total of half your Main full-HD Screen. Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 1920 -DestinationScreenHeight 1080 -DestinationMonitor 'M' -Rows 4 -Cols 2 -Flow 'Y' Example 1b: This is the same as Example 1, except instead of stacking vertically, windows flow in a zig-zag fashion: the first 2 windows are stacked horizontally in one row, then the next 2 are stacked horintally on the next row below. Each window's width is 1/2 the screen's width, and height 1/4 the screen's height. Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 1920 -DestinationScreenHeight 1080 -DestinationMonitor 'M' -Rows 4 -Cols 2 -Flow 'X' Example 2: This opens 4 windows: 3 windows stacked vertically on the left half of your Main full-HD Screen, and 1 window on the top occupying 1/3 of the right half of your Main full-HD Screen. Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 1920 -DestinationScreenHeight 1080 -DestinationMonitor 'M' -Rows 3 -Cols 2 -OffsetLeft 0 -OffsetTop 0 -Flow 'X' Example 3: This is the same as Example 1a, except the windows are on your Left Monitor. Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 1920 -DestinationScreenHeight 1080 -DestinationMonitor 'L' -Rows 4 -Cols 2 -Flow 'Y' Example 4: This is the same as Example 2, except the windows are on your Right Monitor. Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 1920 -DestinationScreenHeight 1080 -DestinationMonitor 'R' -Rows 3 -Cols 2 -OffsetLeft 0 -OffsetTop 0 -Flow 'X' Example 5: This is a nice hack if you have 2 screens. You want the windows to span two screens, rather than being confined to a single screen. Assumes your second screen is to the left of your Main Monitor. This will open 4 windows: 2 your Left Monitor, 2 on your Main monitor, arranged horizontally, each taking up 1/2 the width and 1/2 the height of each screen Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 3840 -DestinationScreenHeight 1080 -DestinationMonitor 'L' -Rows 2 -Cols 4 -OffsetLeft 1920 -OffsetTop 0 -Flow 'X' Example 6: This is a nice hack if you have 3 screens. You want the windows to span three screens, rather than being confined to a single screen. Assumes your second screen is to the left of your Main Monitor, and the third is to the right of your Main Monitor. This will open 6 windows: There will be on the first row, 2 windows your Left Monitor, 2 on your Main monitor, 2 on your Right Monitor, arranged horizontally, each taking up 1/3 the width and 1/3 the height of each screen Position-ExplorerWindow -paths @('D:\My Data Folder\Data1', 'D:\My Data Folder\Data2', 'D:\My Data Folder\Data3', 'D:\My Data Folder\Data\', '\\MYSERVER\public', '\\192.168.0.1\share') -DestinationScreenWidth 5760 -DestinationScreenHeight 1080 -DestinationMonitor 'L' -Rows 3 -Cols 3 -OffsetLeft 3840 -OffsetTop 0 -Flow 'X' .NOTES ################################################################################################################################ # Dependencies: # # - UIAutomation PS module: https://uiautomation.codeplex.com/wikipage?title=Getting%20a%20window&referringTitle=Documentation # ################################################################################################################################ #> [CmdletBinding()] Param( [Parameter(Mandatory=$False,Position=0)] [switch]$ModeEasy , [Parameter(Mandatory=$True,Position=1)] [String[]]$Paths , [Parameter(Mandatory=$False,Position=2)] #[ValidateRange(640, [int]::MaxValue)] [Int]$DestinationScreenWidth , [Parameter(Mandatory=$False,Position=3)] #[ValidateRange(360, [int]::MaxValue)] [Int]$DestinationScreenHeight , [Parameter(Mandatory=$False,Position=4)] [ValidateSet('M', 'L', 'R', 'T', 'B')] [String]$DestinationMonitor = 'M' , [Parameter(Mandatory=$False,Position=5)] #[ValidateRange(1, [int]::MaxValue)] [Int]$Rows = 4 , [Parameter(Mandatory=$False,Position=6)] #[ValidateRange(1, [int]::MaxValue)] [Int]$Cols = 2 , [Parameter(Mandatory=$False,Position=7)] #[ValidateRange(0, [int]::MaxValue)] [Int]$OffsetLeft = 0 , [Parameter(Mandatory=$False,Position=8)] #[ValidateRange(0, [int]::MaxValue)] [Int]$OffsetTop = 0 , [Parameter(Mandatory=$False,Position=9)] [ValidateSet('X', 'Y')] [String]$Flow = 'Y' , [Parameter(Mandatory=$False,Position=10)] #[ValidateRange(0, 1)] [Int]$DebugLevel = 0 ) begin { # NOTE: No longer using UIAutomation Module. # Import Dependency - UIAutomation Module #try { # Import-Module UIAutomation -ErrorAction Stop # [UIAutomation.Preferences]::HighlightParent = $False # [UIAutomation.Preferences]::Highlight = $False #}catch { # throw $_.Exception.Message #} # Error preference $callerEA = $ErrorActionPreference $ErrorActionPreference = 'Stop' if ($PSVersionTable.PSVersion.Major -gt 5) { Write-Host "Module is only supported on Powershell v5 or lower." return } # Get all main monitors resolution # Doesn't work for Windows 7 PSv2 #$mainMonitor = Get-Wmiobject Win32_Videocontroller #$mainMonitorWidth = $mainMonitor.CurrentHorizontalResolution #$mainMonitorHeight = $mainMonitor.CurrentVerticalResolution # Get all main monitors resolution # From: https://stackoverflow.com/questions/7967699/get-screen-resolution-using-wmi-powershell-in-windows-7/7968063#7968063 # The returned screen objects appears to be in order of the physical position of the monitors, from left to right, # regardless of what the monitor's ID in Control Panel's / Settings 'Identify' feature shows.
