The Comparison before the Mirror Sync shows the files in the top folder?
If Yes, then what are the errors thrown in the Sync operation?

You need to use the "Mirror" variant:
"Update" is not an option of it, is a totally different variant.

Additionally, you need to use the "Mirror" variant instead of the default "Two way".

Hi HeinzB,

your PowerShell script is very well done, but you should save it in UTF-8 with BOM and then reload it:
it's currently saved in UTF-8 without BOM, and PowerShell doesn't identify it correctly thus crashing on the double quotes seen as â€œ and â€ instead of “ and ” (Windows/PowerShell ...

If I remember correctly, copying files from a FAT32 memory stick to NTFS leads to difference in files times (seconds).
Is this your scenario?

But there are two other things I have observed.

First:
Why this file is missing on the right?

The error you're receiving on Windows

isn't just caused by an excessively long filename, but rather by a whole host of other possible reasons:

Thanks Zenju!
Now the colon works as expected!

Appending a colon in the Exclude filter, the folder is not excluded but the files in it are excluded, despite they are not *.db.

I have noticed that this way will be filtered out also this folder and its files despite they are not *.db:
c:\Users\Dave\AppData\Local\Microsoft\OneDrive\EBWebView\Default\EdgeCoupons\coupons_data.db

Appending a colon (:) to the filter expression, like stated in the manual, doesn't seem to work ...

The way Drag & Drop works now seems pretty useless to me.

If I select a folder, it does its job and places it where I drop it.

If I select multiple folders, it only considers the first two and places one on one side and one on the other, depending on where I Drop it.

But it's unlikely that a ...

1) Try disabling in Tools / Options the radio-button [x] Copy DACL, SACL, Owner, Group

2) You're launching FFS with Administrator privileges, and Drag and Drop doesn't work between apps launched with Administrator privileges and apps launched without Administrator privileges.

I linked this section of the Manual just to explain the OP the mechanism of the sync.ffs_lock file.

Backing up the entire C: drive with FFS is not a good idea, there are more suitable tools for this.

With FFS, it's better to select only specific folders containing data.

Anyway, my guess is that the disk has some logical corruption.
I suggest you to check and correct it with the following ...

I ran the following test on a PC that doesn't have symbolic links created by me, which therefore only contains the standard Windows 10 symbolic links.

Hi Allen,

They have changed the link, I have updated my post with the correct one.

To view this system folder you need to untick also "[x] Hide protected operating system files" in Folder Options.

If you need these two options, FFS must be run as administrator.

Maybe you had UAC disabled before while it is enabled now?

Uncheck them and try again.

I have seen this type of corruption when I had my pc set to dual boot with different Windows versions.

Hi Plerry,
I think wttyyyy meant file path or name valid for the Cloud file system but not valid for the Windows file system.

Running the setup file is the only action needed, but the .key file must be present in the same location of the setup file during the install.

On the NAS:

- create a directory named "Source A" and move the relevant files and directories in it
- duplicate "Source A" in "Source B" and "Source C"

Please show your sync configuration.

Why did you need to copy the Thunderbird Profiles 2021 directory contents to C:\Users\bjac\Documents\Data ?
It is not better to leave it alone and copy it as is when you copy C:\Users\bjac\Documents\Data with sub-directories to the external drives?

A setup like this?

Source A (Mirror to) NAS\Source A\
Source B (Mirror to) NAS\Source B\
Source C (Mirror to) NAS\Source C\

This way they are all independent from each other.

Please give me the exact folder names, may be there is something strange/wrong with those names.

Did you push the Compare button again after the renames?

The filenames are not identical: on the left side the year is four digit while on the right is two digit and there is an underscore after 20.
