Files with empty modification date cannot be filtered

[olivier]

Hi,
I am using your great software since some time, but each time I sync my profile some files get copied over and over.
Those are files copied on my laptop from linux, with a modification date at 1970. And on my driver for backup they have the modification date of the last sync. As the dates do not match, they are copied again at every run.
I tried setting time filters (like past 100 days; or as shown here https://freefilesync.org/manual.php?topic=all#select-time-span), but in both cases those files are shown in the list.
How could I do ?
Many thanks in advance

Are you using Windows or Linux, any which FreeFileSync version?

[olivier]

I am on Windows 10, using latest version 10.12

Can you try to sync only one of these files (= select one via mouse + press Enter) and send me a Process Monitor trace of the sync operation? https://freefilesync.org/faq.php#trace

Also, please try the following version (I have a hunch, regarding a workaround):

Hi,
Thanks for your quick feedback!
Here is log file, http://ge.tt/1jjPMJw2
Regarding beta software it looks the same. (at 1st sync it showed the files as usual, performed the sync and press refresh, the same files are shown again).

According to the process monitor log, you should have seen a warning message during file copying with more details regarding G:\QCNG\20 Etude\202 Electrique\doc fournisseurs\I2SE\calibration\evse.pib.
(Unless you've set "ignore errors", in which case the warning is still logged and shown on the results panel).

[olivier]

Yes, i've set the ignore error some time ago.

I've got a warning for recycle bin not supported
And error for each of my faulty files an error about modification date:

Impossible d'écrire la date de modification de "G:\QCNG\20 Etude\204 Logiciel\I2Se_calibration\calibreoui.b337.ffs_tmp".
A FAT volume can only store dates from 1980 to 2099:
write time (UTC): 01/01/1970 00:09:53 (116444741930000000)
Code Erreur 87: Paramètre incorrect. [SetFileTime]

For sure it explains the cause of the modification date of the files set the current date on my drive.
But how can I avoid those messages ?
As the sync type is 'mirror', it could be great if I could sync only files modified in my laptop in the last x days (thus not taking into account that the file on my backup drive has a recent modification date)

I'd simply "touch" these files from the Linux command line and be done with it.
