我在使用Canon Digital Photo Professional 4.0 ( dpp400u2.exe ) 轉檔時有遇到如上的錯誤訊息，現象為：
1. 按下Convert and Save有5%機率按下convert後不會轉檔也沒事情發生。有95%機率會跳出錯誤訊息 "Under these settings, files will be saved with duplicate file names"
2. 按下Batch convert也會有此情形
3. 關閉DPP後重開沒有用
4. 砍掉DPP4再重裝沒有用
5. 調整轉檔畫質/轉檔大小沒有用
6. Batch模式下，選別的檔案沒有用，調畫質大小沒有用，更改批次檔名沒有用。

解法：
把 "%appdata%\Canon_Inc_IC\DPP4\Application\Temp\" 資料夾內的暫存檔與裡面的目錄全部刪除。



The issue is the error message
"Under these settings, files will be saved with duplicate file names"
will occur when I try to convert/batch convert photo:
1. There is 5% chance when i press "Convert" in "Convert and Save" and nothing happened, none of photo would be converted. 95% chance will jump out above error message.
2. "Batch convert" happened, too.
3. Issue still occur with close DPP and open again.
4. Issue still occur with remove DPP4 and install again.
5. Issue still occur with change image quality and resolution
6. "Batch convert", issue still occur with change batch convert photo, and 3. 4.

Short term solution:
Delete all files and folders in "%appdata%\Canon_Inc_IC\DPP4\Application\Temp\" folder.
