You can change the settings in the Batch Image Rotate/Flip Options dialog box to control where ACDSee places modified images, how to handle file duplication conflicts, and specify whether you want to preserve the last-modified date of the file when you use the Batch Rotate/Flip Images tool.
To Set the Rotate and Flip Options:
Rotate and Flip Options
| Force lossless JPEG operations | Rotates JPEG images without decompressing and re-compressing the JPEG information. As a result, the image does not lose quality when rotated or flipped. | 
| File options | Specifies where to place the new images. Select one of the following options: 
 | 
| Overwrite existing files | 
 | 
| Preserve last-modified dates | Retains the date and time properties of the file. | 
| Remember and apply the last rotation performed | Automatically applies the same settings the next time you rotate an image. | 
| Auto-close progress dialog if all operations succeed | Automatically closes the dialog box after all images have been adjusted. | 
| Save current settings as default | Stores the current settings and applies them the next time you use the Rotate/Flip Images Wizard. |
