You can use custom sorting to customize the order of files in the File List pane. After custom sorting your files, ACDSee automatically saves the file order for the selected folder until you change it or delete the custom sort.

To customize the sorting order of your files:

1. In Manage Mode, select one or more files.
2. Drag the selected files to a new location in the File List.
3. To delete a custom sort, click View | Sort, and select Delete Custom Sort.

For more information about sorting your files, please see Sorting files in the ACDSee Help file.
