Powershell Script to Copy Files at Multiple Destinations Using Regex

Here is a parameterized Powershell script to copy the files from one location to multiple destinations. You can also rename the files and use various date formats to put the files in yearly/monthly folder. Once the files are successfully copied, you have an option to delete the file from source location.

Usage

<# Explanation - Source Excel file name contains 4 digit store number (example: "Report_Store_0278.xlsx"). We want to copy those files to "business" folder with only store number (i.e. "0278.xlsx") and also archive the same file in a folder with today's date (i.e. "archive\20180215\0278.xlsx"). Once copied, we want to delete the files from source folder.
#>
CopyFiles.ps1 -SourcePath '\\networklocation\source\' -SourceFilePattern 'Report_Store_\[([0-9]{4})\].*.xlsx' -CopyFiles '\\networklocation\business\${1}.xlsx','\\networklocation\archive\%date{yyyyMMdd}\${1}.xlsx' -DeleteSource 1

Source Code

# Copy the following code into a file called CopyFiles.ps1
param(
     
    [string]$SourcePath = $(throw "SourcePath param required"),
    [string]$SourceFilePattern = $(throw "$SourceFilePattern param required"),
    [string[]] $CopyFiles = $(throw "CopyFiles param required"),
    [int] $DeleteSource = 0
)
 
<#
$SourceFile = "C:\Temp\Opterus\Source\S([0-9]+).*.xls"
$CopyFiles = @("C:\Temp\Opterus\Destination\*.*", "C:\Temp\Opterus\Archive\%date{yyyyMMdd}\S`${1} Merchandise Report.xls")
$DeleteSource = $true
