Update:

I have changed:
Preferences > Transfer > Edit > Transfer mode
from 'Autamatic' to 'Binary' and now the file transfer with the right size.

Cheers

Hi all,

Thank you very much in advance for helping.

I've observed that every time I synchronise a directory, some files always needed to be updated.
Look closely, I noticed that the reason why this happens is because the file size is different.
So a 610Kb file in my computer, it transformed into 593Kb when I upload it to the server.
It happens with xml and js files.

Any idea why this happens?

Thanks
