按类型组织文件(Organizing files by type)

 我有这个脚本，它定期运行以收集桌面文件，并通过文件类型将它们组织到备份驱动器上的单个文件夹中。 
 
function get-destbytype($ext) 
{
    switch ($ext)
    {
        { $ext -match '(jpg|png|gif|bmp)'} { "images" }
        { $ext -match '(divx|mpeg|avi)'} { "videos" }
        { $ext -match '(cs|js|java|py|class|vbs|jsp)'} { "code" }
        { $ext -match '(sql|ps1|pl|py)'} { "scripts" }
        { $ext -match '(zip|7z|rar)'} { "compressed" }
        { $ext -match '(ppt|pptx|doc|docx|pdf)'} { "documents" }
        { $ext -match '(csv|xls|xlsx)'} { "spreadsheets" }
        { $ext -match '(exe|dll|jar|ear|bat|cmd)'} { "executables" }
        { $ext -match '(txt|log)'} { "text" }
        { $ext -match '(msg|htm|html|lnk)'} { "miscellaneous" }
        { $ext -match '(properties|xml|ini)'} { "config" }
        default {"$ext" }
    }
}

$dirtyfolder = "C:\Documents and Settings\user\Desktop\"
$org = "$nas\Desktop\ORG"

ls $dirtyfolder/* | ? {!$_.PSIsContainer} | %{
  $dest = "$($org)\$(get-destbytype $_.extension)"
  if (! (Test-Path -path $dest ) ) 
  {
    write-host "creating $dest"
    new-item $dest -type directory
  }
  mv -path $_ -destination $dest 
}
 
 剧本经过了彻底的测试，在我能想象到的大多数情况下似乎运行良好。 最近当第一次遇到.csv文件时，它们被移动到名称的新文件夹中 
 
 code spreadsheets 。 
 
 这显然是因为.cs文件应该转到code文件夹，并将.csv文件转到spreadsheets文件夹，并且该脚本不区分.cs和.csv 。 
 
 我如何修改脚本不做这件事？ 
 
 也可以做什么来排除扩展名为.lnk桌面快捷方式？ 

I have this script which runs periodically to collect desktop files and organizes them by the file type into a single folder on backup drive.
 
function get-destbytype($ext) 
{
    switch ($ext)
    {
        { $ext -match '(jpg|png|gif|bmp)'} { "images" }
        { $ext -match '(divx|mpeg|avi)'} { "videos" }
        { $ext -match '(cs|js|java|py|class|vbs|jsp)'} { "code" }
        { $ext -match '(sql|ps1|pl|py)'} { "scripts" }
        { $ext -match '(zip|7z|rar)'} { "compressed" }
        { $ext -match '(ppt|pptx|doc|docx|pdf)'} { "documents" }
        { $ext -match '(csv|xls|xlsx)'} { "spreadsheets" }
        { $ext -match '(exe|dll|jar|ear|bat|cmd)'} { "executables" }
        { $ext -match '(txt|log)'} { "text" }
        { $ext -match '(msg|htm|html|lnk)'} { "miscellaneous" }
        { $ext -match '(properties|xml|ini)'} { "config" }
        default {"$ext" }
    }
}

$dirtyfolder = "C:\Documents and Settings\user\Desktop\"
$org = "$nas\Desktop\ORG"

ls $dirtyfolder/* | ? {!$_.PSIsContainer} | %{
  $dest = "$($org)\$(get-destbytype $_.extension)"
  if (! (Test-Path -path $dest ) ) 
  {
    write-host "creating $dest"
    new-item $dest -type directory
  }
  mv -path $_ -destination $dest 
}
 
The script was tested thoroughly and seems to run fine in most cases I could imagine. Recently when .csv files were encountered for the first time, they were moved into a new folder by the name
 
code spreadsheets. 
 
This is obviously because the .cs files are supposed to go to the code folder and the .csv files to the spreadsheets folder, and the script does not distinguish between .cs and .csv.
 
How do I modify the script to not do this? 
 
Also what can be done to exclude desktop shortcuts with extension .lnk?
