function Get-BPAFolder {
    <#
        .SYNOPSIS
            Gets AutoMate BPA folders.
 
        .DESCRIPTION
            Get-BPAFolder gets folders objects from AutoMate BPA. Get-BPAFolder can receive items on the pipeline and return related objects.
 
        .PARAMETER InputObject
            The object(s) to use in search for folders.
 
        .PARAMETER Name
            The name of the folder (case sensitive). Wildcard characters can be escaped using the ` character. If using escaped wildcards, the string
            must be wrapped in single quotes. For example: Get-BPAFolder -Name '`[Test`]'
 
        .PARAMETER ID
            The ID of the folder.
 
        .PARAMETER FilterSet
            The parameters to filter the search on. Supply hashtable(s) with the following properties: Property, Comparator, Value.
            Valid values for the Comparator are: =, !=, <, >, contains (default - no need to supply Comparator when using 'contains')
 
        .PARAMETER FilterSetMode
            If multiple filter sets are provided, FilterSetMode determines if the filter sets should be evaluated with an AND or an OR
 
        .PARAMETER Path
            The path containing the folder.
 
        .PARAMETER Parent
            Get folders that contain the specified folders. This parameter is only used when a folder is piped in.
 
        .PARAMETER Type
            The folder type: AGENTGROUPS, CONDITIONS, PROCESSAGENTS, PROCESSES, TASKAGENTS, TASKS, USERGROUPS, USERS, WORKFLOWS
 
        .PARAMETER SortProperty
            The object property to sort results on. Do not use BPAServer or TypeName, since those are custom properties added by this module, and not exposed in the API.
 
        .PARAMETER SortDescending
            If specified, this will sort the output on the specified SortProperty in descending order. Otherwise, ascending order is assumed.
 
        .PARAMETER BPAServer
            The AutoMate BPA management server.
 
        .INPUTS
            Agents related to the following objects can be retrieved by this function:
            Workflow
            Folder
 
        .EXAMPLE
            # Get folder "My Folder"
            Get-BPAFolder "My Folder"
 
        .EXAMPLE
            # Get folder containing workflow "My Workflow"
            Get-BPAWorkflow "My Workflow" | Get-BPAFolder
 
        .EXAMPLE
            # Get workflows in "My Folder"
            Get-BPAFolder "My Folder" -Type WORKFLOWS | Get-BPAWorkflow
 
        .EXAMPLE
            # Get folder "My Folder" by path
            Get-BPAFolder -Path "\PROCESSES" -Name "My Folder"
 
        .EXAMPLE
            # Get subfolders of "My Folder"
            Get-BPAFolder "My Folder" -Type PROCESSES | Get-BPAFolder
 
        .EXAMPLE
            # Get folders using filter sets
            Get-BPAFolder -FilterSet @{ Property = "Path"; Comparator = "contains"; Value = "WORKFLOWS"}
