Sync fails because new files are addeded before removed files are deleted?

[wombat]

Hi All:

Love the program but have run into this issue several times.

When mirroring a drive to a backup, most often new files are to be synced and removed files are to be deleted. However, is some cases the target drive is nearly full, and the program appears to try to add new files before it deletes the ones to be removed. When that happens, the sync fails.

Is there a setting to instruct FreeFileSync to delete files from the target drive before it starts to add new files, or is that a potential feature request??

Many thanks in advance,

wombat

FFS does deletions first.
If you have it set to delete files to the Recycle Bin though, this isn't freeing space on the drive

Only correct if you disable "Fail-safe file copy" (in the FFS GUI under Tools / Options);
not if you enable "Fail-safe file copy".
See e.g. viewtopic.php?t=9094#p32788

Thanks xCSxXenon and Plerry!

Got it : ) I have some pretty large files, so if FFS is duplicating even a few of them, I'll run out of space.

IS there a setting for how deleted files are handled as well ("Delete files" method referred to in the referenced post)?

I don't see that option under Options in version 14.6.

This is true. I had incorrectly assumed that OP had enough free space for at least a temporary duplicate of the largest file. FWIW, if you are that close to the edge, you are likely losing performance and should upgrade the drive(s)

It's in FFS options

Don't look under Options.
For at least 14 years, the "Delete files" method can be found in the Synchronization Settings (F8), and is nowadays called "Delete and overwrite".

Found it, thanks!!!
