Software / Apps For Syncing Between Devices

[joko]

Can anyone recommend what the best FREE software / apps available so I can sync documents etc between 4 devices.
i want to be able to make or edit a document on one device and view on the others.

a win7 laptop

a win 7 tablet pc.

a 7" samsung galaxy tablet

and an android phone.

i know there are various ones with a small amount of free space, but some have limits such as only 3 devices allowed, or only 100 files etc
also some have very limited space, so the more the better really.

i realise as i want free i will have to compromise somewhere - but i want all 4 devices connected

so any recommendations for me to try out?

thanks

on my laptop when i launch fiefox, under tools then options, i can select syn across all devices and it will sync my kobo arc tablet. is that what you mean?

similar, but that will only sync firefox, won't it?

not documents, folders, music etc

I use Google Docs for documents - can be accessed and edited from any pc/laptop/tablet in the world, if it is connected to the internet.

I would not want to sync all my music and photos across all devices - I have many GBs of music and it would not fit on my tablets or phone.

I do have a NAS hard drive - this is an external hard drive that connects to my router and stores everything. All my devices can connect to that over wifi.

Google Music stores all my music in the cloud and can be used on my Windows machines and Android, wherever I am. Both your tablet and your phone are Android so should work well.

Photobucket will store your photos in the cloud and can be accessed from any device that is connected to the internet.
