Checking for duplicate items:
The program will automatically compare new items that have arrived with items that you already have in this folder, and try to automatically merge the data in them.
By default, the auto-resolving duplicates algorithm ("Search and try to merge duplicate items...") is enabled in the Product "Options..." Advanced tab, available from the product menu.
If the program is not able to safely merge duplicates or resolve conflicts, the program will backup all problematic items into a special "Duplicate issues" folder and notify you. Then, you can deal with them manually.
The items that are detected as duplicate items, but cannot be merged, are placed into the "Conflicts" sub-folder. You can open both the original version (that is currently in your original folder), and the arrived conflicting version by right-clicking on the item in this folder and selecting "Compare With Original Item" in the menu.
If items are automatically merged during sharing, the original items stored in your folder before merging will be backed up in the "Backup" sub-folder. If there are many merged items in the folder, the original folder backup will be created here, with the exact date and time of the backup, with all the items stored there before they merging.
When you've reviewed the conflicts and any created backups, you can delete the "Duplicate Issues" folder. If any further conflicts or backup instances occur, this folder will be created again.
If auto-resolving feature is disabled, the functionality described here is also disabled and application will not check for duplicates at all.
NOTE: The sender will not receive any changes of the above if he uses the "synchronize only" mode or "view" right for sharing folder.
