UltraDefrag 5.0.5 (32-bit)

UltraDefrag 是一款完全免費的開源磁碟重組工具，主要用來整理硬碟碎片、提升讀寫效率。它最特別的地方在於支援開機時執行重組，能處理系統檔案或鎖定中的磁區，這在一般重組軟體中較少見。此外，它也提供針對單一資料夾或檔案的重組，以及精簡的命令列模式，適合進階使用者。這套軟體長期以來持續維護，更新頻率不算高，但在同類工具中屬於穩定且評價不錯的選擇，並非主流首選，但有一定支持者。

如果你需要一套免付費、可攜帶或免安裝的重組工具，而且偶爾想處理開機時才能動的系統檔，UltraDefrag 會是實用的選項。與 Glary Utilities 這類整合型優化工具相比，它功能單一、專注在重組，沒有多餘的系統清理或登錄檔修復，因此更輕量。授權為開源軟體，使用上沒有付費疑慮，但官方介面以英文為主，雖然內建多國語系且可切換中文，但部分說明文件仍以英文呈現，對不熟悉英文的使用者可能需要稍微摸索。

UltraDefrag是一款完全免費且速度極快的磁碟重組軟體，與其他軟體不同之處，它具備有在開機時可執行重組工作的功能。
