DriveLetterView 是一款免費、免安裝的簡易工具程式，可讓您檢視系統中所有磁碟機代號，包括本機磁碟機、遠端網路磁碟機、CD/DVD 光碟機以及 USB 抽取式磁碟機 (即使目前並未插入 USB 裝置亦可檢視)。
這款軟體亦可讓您輕易地變更 USB 裝置與遠端網路共用磁碟機的代號及刪除目前並未插入的 USB 裝置的磁碟機代號。您亦可用這款軟體將所有磁碟機清單匯出為 txt/csv/html/xml 檔。
在 Windows 7/2008/Vista 中，若要變更或刪除磁碟機代號，請在主程式 DriveLetterView.exe 上按滑鼠右鍵叫出快顯功能表，然後點選「以系統管理員身分執行」。若無管理員權限，這一工具程式雖會顯示磁碟機清單，但您不能變更或刪除磁碟機代號。
注意：請將下載回來的繁體中文語系檔解壓縮後將 DriveLetterView_lng.ini 放在程式同一資料夾，程式啟動後即為繁體中文介面。

DriveLetterView 原文簡介：
This application is a simple utility that allows you to view the list of all drive letter assignments in your system, including local drives, remote network drives, CD/DVD drives, and USB drives – even if they are not currently plugged. It also allows you to easily change a drive letter of USB devices and remote network shares, as well as to delete a drive letter of USB device that is not plugged. You can also use the software to export the list of all drives into text/csv/html/xml file.
Note: In order to change/remove drive letters on Windows 7/2008/Vista, you have to right-click on DriveLetterView.exe and choose ‘Run As Administrator’. If you run it without admin rights, it can display the list of all drives, but you won’t be able to change/remove a drive letter.
