Conflicts
Go to the “Conflicts” window choosing the Options:Conflicts item from the “Option” menu, or clicking on the “Conflicts” icon on the drawer view. You will be shown the panel represented by the picture here aside. On this panel you can tell FS how to behave in case of conflicts.

A conflict can occur when FS is going to delete or replace a file which has something new since the last sync/backup. "Something new" means that the file FS is going to delete has been modified or it has just been created after the last sync/backup. The conflicts are the following:



A - Backup and Exact Backup
1 - If both the files have been modified after the last backup and the source file is the most recent. User's choices: skip, replace destination (ask or not).

2 - If a destination file has a more recent modification date than its related source file. User's choices: skip, replace destination (ask or not).
B - Exact Backup only
1 - If after the last exact backup a destination file has been modified, and its related source file has been deleted. User's choices: skip, delete destination (ask or not).

2 - If after the last exact backup an item has been added to a destination folder, and its related source parent folder has been deleted. User's choices: skip, delete destination (ask or not).

C - Sync and Exact Sync
1) If both the files have been modified after the last synchronization. User's choices: skip, copy the most recent (ask or not).

D - Exact Sync Only
1) If after the last exact sync a file has been modified, and its mirrored file has been deleted. User's choices: copy back the file, delete the file (ask or not).

2) If after the last exact sync a file has been added to a folder, and its mirrored parent folder has been deleted. User's choices: copy back the file, delete the file (ask or not).

E - File versus Folder
1) If a file is going to replace a folder with the same same User's choices: copy the file and replace the folder, don't copy the file, leave the folder untouched (ask or not).

Ask
If you mark the check-box "Ask", you will be asked by a dialog window for choosing the proper behavior when a conflict occurs. On this dialog (see picture here aside) you will be able to see the pathnames of the two files, their modification and backup dates, and you will be able to:

• Open the files with their application and inspect their contents.
• Reveal the files in the Finder.
• In case of sync and if both the files exist, you will even be able to invert the direction of the copy (source-destination to destination-source and vice-versa).
• Skip these files or continue the sync/backup.

If the Sync/Backup had been launched by a timer (or by the Sync&Quit option on the Preferences panel), FS would not display this dialog for asking, but it will behave as specified by the radio-buttons on the Conflicts panel.
