You forgot to exclude "\DATA 1 Backup\" for the first folder pair. Also you probably have "ignore errors" active, otherwise you would have seen the warning *before* starting the sync.


Zenju,
Thank you, you are correct, I did have "ignore errors" active and configured for running as a batch ...

Plerry,
Thank you for the assist, I have made the changes that you recommended and all appears to be functioning as expected.
However I am still getting the error,
16:44:56 Warning The following folders are significantly different. Please check that the correct folders are selected for ...

To add to the above:
Unless you have disabled it, you did receive a warning from FFS to the extent that there was an overlap between one or more of your sync locations, causing above "unexpected" results.


I did get a warning after it was completed, I don't recall seeing anything before ...

Per your first left-right pair, you are synchronizing D:\ (left) to the root of Q:\ (right), thereby creating an overlap between your multiple folder pairs. This can cause the sort of problems you are experiencing.
Because D:\ does likely not comprise a (root)folder Data 1 Backup, the data in Q ...

Thank you Plerry, I'll look into that. It's always nice to have a fresh pair of eyes take a look.

boris,
First, I apologize, it was not my intention to suggest that you are not intelligent. We all have times when we just can't figure something out, no matter how hard we try, as in my handle.

In your posts I could feel your frustration as I have "Ben There" at times also.
"I have tried this ...

boris,
In reference to Your reply "I really wonder if being in a community group" is unfair and uncalled for and a sure way to find yourself unable to get help in the future.
Plerry gave a clear reference to solve the issue you have. By your own admission, you state that you are incapable of ...

I essentially have 6 drives, 3 operable and 3 backup. One internal, one external with 2 partitions and one external with 3 partitions for backup.

I have 7 "*.ffs_gui" files, three of these are on the main partition ...

UPDATE: Problem Solved - Explanation - New problem

Brain Fart Active: While I had verified that I had permissions to the files "*.ffs_gui", I had not verified permissions to the drive. So checking this I find that system is the only user that has write permissions. Apparently this is not enough for ...
