I work on a lot projects, some local saved, some accessing via ftp, sometimes working withe an USB-Stick, sometimes changed from another person...
So if I come home I sometimes have to update my local project directories. For this a synchronisation tool / assistent would be great - for a simple examle like the filezilla feature which can mark new, resized or not existent files with different colors.
(For the aspect, that another person has made changes, file (code) compare would be great too - but that was requested in a different post already - and yes, I gave my appropriate vote )
