由日本人開發、不用安裝兼小巧的免費軟體，能為您恢復被永久刪除(Shift+ Delete! 、清空資回收筒)的檔案。雖然其恢復資料能力有限，但論速度不俗，對於恢復剛刪除的資料，幾分鐘就可以做到。

DataRecovery is freeware and written by TOKIWA
to undelete accidentally deleted files even from recycle bin.

But DataRecovery doesn't assure that all files deleted can be recovered successfully.It mostly depends on your system/configuration and we can't support each of all those varieties.
