Is it possible to transfer in parallel for only modified tasks of different developers

If you mean by “synchronizing” to use SVN or GIT, that does not work for the binary files, since it changes the file-date by the checkout and there is no way to preserve it (at least was it on that way a couple years ago when I looked at it).

What works for me is to to archive the project by 7-Zip with the following options and restore it then from there on another computer:

7zG.exe a -t7z -mtc -mta -mmt=on "%SAVE_PATH%\%Year%-%MonthDay%-%DayMonth%%PRJ_NAME_EXT%\%PRJ_NAME%.7z" "..\%PRJ_NAME%"

Software like rsync might work as well with the right parameters, but I never tried it.
