Selected file.

When you set or modify the image processing properties, these properties are “assigned” to the selected file only. In both modes (thumbnail or normal) a File may be selected by a left mouse click on the file. Only one file can be selected at time.

Marked file(s).

If you wish to apply image-processing properties to more than one selected file, create a group of files by marking them. Use the right mouse button in thumbnail mode or check files in normal mode to make file(s) marked. Image processing properties, which have been set to a selected file, can be applied to all marked files using the “Apply to all marked” button. After clicking this button, its font color will be changed to red - it means that all corresponding properties have been applied to all marked files.

Please note, that the “Process Now” button activates all marked files only; therefore don't forget to mark all the files that you wish to include in the batch process.
