FreeFileSync Forum

The topic "Disk full" has been discussed already several times in this forum.
E.g. viewtopic.php?t=8897&p=31857

It is not necessarily you (yourself) that opened or modified a file.
Some software tools (like e.g. some anti-virus programs) have the nasty habit of doing that for you ... ;-)

I am not sure what is, or is not, being logged in those cases. Irrespective of logging: the sync is not automatically performed by FFS the next time the target is/becomes on line. However, you could use RTS for that purpose: The function of RealTimeSync is to execute a command line ... when a direct...

> Why do i have in batch file left and right pairs in a given order > but FFS does not consider the order at the end? Order is only relevant if there are dependencies between sync locations, forming an overlap. Overlaps must be avoided, because they create potential sync conflicts or ambiguities. An...

(I re-used you location notation, although the combination of drive-letters and forward slashes appears strange or simply incorrect to me) The fact that you first list C://folder/folder -> D://folder/folder as your first folder pair AND then D:// -> P:// as your second folder pair does not mean that...

> I am running FFS on a work computer (managed by the organization)

Looks like illegal use: https://freefilesync.org/faq.php#commercial
So, perhaps it is just your companies way to protect itself against legal liabilities.

Note that HOSTNAME and ComputerName are different beasts.
You (harryytm) never reacted to my initial reply about ComputerName ...

> The reason given is always that it doesn't exist on the right size. This suggests you are not using the proper left-right base-locations. If you are sure your right-side files are in the desired location, then you should define your left and right base-location such that the path to your files rel...

> ... and what on earth is a folder pair? The absolute very first item of the FreeFileSync (FFS) Manual is: "Basic Usage: 1. Choose left and right folders." which obviously constitutes a (left-right) folder pair ... It seems you are trying to sync between Y:\Games and Y:\Games\C drive stuf...

Instead of using the "Time stamp (Folder)" option in Versioning, try using "Time stamp (File)" or for your case (keeping just a single previous version) "Replace". When using the "Time stamp (Folder)" option, files may get deleted from "older" Versio...

Have you tried to follow the manual?

> but it appears that FFS is not capable of doing this.
By now, you should have understood that it is not FFS, but rather Linux that is not capable of doing what you want.

It depends on what type of encryption is applied. As FreeFileSync (FFS) works at file-level, if your encryption is also at file-level, FFS will gladly sync files in their encrypted form. Similarly, if you can mount your encrypted drive or folder(s) as a seemingly unencrypted drive or folder (some en...

Zenju's E-mail address can be found at the bottom of the FFS Home page.

In Windows, next to typing \\nas\share1 in the FFS location window, you can also drag a folder from e.g. Windows (File) Explorer and drop it into the FFS left or right location window. I believe on a MAC you can do the same by dragging a folder from Finder and drop it into the FFS left or right loca...

Not an automatic one:

viewtopic.php?t=7690

But it seems you already discovered the manual way to do it.

Theoretically, files can have an identical checksum and still differ in content.
That is however very, very unlikely, and, as explained in said threads, not the reason why FFS does not use hashes.

> I am assuming in sync settings, this would just be the mirror option? Both the Update and Mirror sync variant will only modify your right-side location ; not your left-side location. The Update sync variant will not delete any item from your right-side location that does not (or no longer) exist i...

For good reasons, FreeFileSync (FFS) does not use hashes (as discussed in this forum in multiple threads).
Instead, FFS uses a plain bit-by-bit comparison.

The problem seems to be that you created an overlap between your two folder pairs. Your first right location is D:\ , your second one D:\Photos . But D:\Photos is obviously part of D:\ , so there is your overlap. I would expect FreeFileSync (FFS) gave you a warning to that extent. There are (at leas...

There is no reason to expect that the FFS estimate would be more accurate than what e.g. Windows (File) Explorer predicts.

Correct. Any Excluded or not Included files and folders are simply not considered for any sync actions. The deletion of all not \202?\ folders and their content from your backup seems a one-time action and should be not too hard to do manually. If you want, you could also use FFS: Leave your Include...

After running a Compare:
Tools / Export File List

You could consider using Versioning. That will retain all files deleted or overwritten (updated) by FFS, in a self-selected location, for as many versions as you select and for as long as you select.

In- and Exclude Filter definitions are relative to the root of your base locations.
If Main is one of your base-locations, you need to exclude
\FolderA\A_Exclude\
not just
\A_Exclude\

In- and Exclusion Filter rules are relative to the root of your base-locations. Because your base-locations are D:\ and E:\Backup (and not D:\Dropbox and E:\Backup\Dropbox ), you need to exclude \Dropbox\.dropbox.cache\ Your present exclude rule \.dropbox.cache\ would exclude the folder .dropbox.cac...

> If I drag a folder drop on the + icon, will automatic add another new path. If I drop on the address bar, then replace the exist path. Could make sense. The location dropped onto the "+"-icon would then obviously become the left-side location of the new pair. On the other hand, it saves ...
