recurseCopyDuplicates.ps1

Enter file contents here<#
20150910 dc - Recursively copy files specified of the same name.ext from various folders
and then write to a new path renamed for each instance with numerical values incrementing

Be careful we use Get-Content which loads the entire file listing into memory. Hint: If the file list
becomes something like 1 TB; this will be loaded entirely in memory. The alternative is to
modify the listing using a new object to stream the file rather than load all at once.

Usage: recurseCopyDuplicates.ps1 -s SourcePathToSearch -f FileNameToFind.Ext -d DestinationPath

Examples:
Always include the trailing blackslash "\" in your path
recurseCopyDuplicates.ps1 -s 'C:\foo' -f repeatingData.txt -d 'D:\foo bar\'
recurseCopyDuplicates.ps1 -s C:\foo\ -f *.csv -d D:\foobar\
