FreeFileSync Forum

@Plerry As far as I know, "Fail-safe file copy" uses ".ffs_tmp" even if a file is being newly created (without overwriting a pre-existing version). Otherwise an incomplete file would have the final filename.

Now I know what the bug is. When creating a *large* file, FFS does show the percentage for that file. "Pause" freezes the displayed per-file and total percentage, which is misleading because the file creation continues.

The worst part is that this makes FFS seem unreliable, as I described: The UI ...

Assuming you have kept "fail-safe file copy" checkmarked (in Tools/Options)
Yes.

if FreeFileSync (FFS) intends to overwrite an existing file by a newer/different version
No, I mean *creating* a file that didn't exist on the right. I clicked "Pause", FFS says "Creating file ...", but that ...

Some files have a different file name (ending with ".ffs_tmp") while being created, but not all files. I don't know what this depends on, maybe files without a file extension (without "." in their name) are affected. Version 14.5.

If a file creation gets interrupted for whatever reason (USB cable unplugs, PC crashes, power outage, forced reboot, ...), subsequent comparisons by file date and size won't detect the file as out of sync? This would lead to unnoticed data loss.

FreeFileSync should make file names and dates ...

You over estimate the competency of users. xCSxXenon, 19 Dec 2021, 17:48

You underestimate the competency of many users.

As usual in such situations, the software can say "if unsure, choose X". On the other hand, those who do know what they are doing should have the option.

Because files in different locations with identical size and timestamps are not always identical?
Increases data loss risk basically


Let the users decide whether they want to consider files with identical size and timestamp as identical. In many situations, users know that those files are ...

Why not consider files with identical size and timestamp as identical? That could be an option for the user to choose.

Or allow right click -> "Rescan" specific folders, so that I can rename them such that they are named the same (and FreeFileSync takes that into account), without rescanning everything (which takes long).

The main issue is that I want to sync a few files that are inside big renamed folders. So just ...

FreeFileSync often doesn't detect when a folder has been renamed or moved. Instead of renaming it at the other synched location accordingly, it suggests deleting it and copying it again (which takes much more time).

Please try to detect it automatically.

Or at least allow the user to tell ...

Just poll the setting exactly when errors occur. Like currently.

Currently, changing the setting is possible only in one direction and only at specific times. This limitation doesn't make much sense.

Example scenario:
* Undo an accidental click on "Ignore all"

or:
* Start sync, then it turns out that I have to leave, but want as many files as possible to be synched until I return, i.e. future errors should be ignored.

It would be good to be able to enable/disable "ignore errors" anytime (at the two locations where currently a static message is displayed that errors are being ignored).

Adding it as an option would be great indeed!

Any plans to fix this issue?

The waiting time makes it seem to the user like the button isn't working. No page nowadays takes 30 seconds to load.

How exactly does the offending formulation help to prevent spam, as opposed to a neutral formulation?

What about a less offending formulation, and no waiting time? The waiting time makes it seem like the button isn't working.

I tried including links to Wikipedia to make my post clearer, and the preview button reacted very slowly and yielded the following message:

It seems that FreeFileSync copies files in the order that corresponds to breadth-first search. Please allow the user to choose depth-first search instead, at least as an option. Depth-first search is default in most other software, and is more intuitive.

Depth-first search is also much better in ...
