In addition to what MiK546 said, if you want to send more than 1 file at a time then first navigate to the directory where your files are, click on the menu and click "Share", now you can select more than 1 file to send. Using bluetooth is ok for small files, say a few MBs, anything larger would be really tedious.

Bluetooth ~ 70KB/s
WiFi ~ 1 - 2MB/s

go to file manager → long press on file → share → bluetooth. or you can go to your computer and search for devices(turn on bluetooth on phone) and connect it, than search for browse device or something like that(not sure how it's called in windows and where is it, as i' linux user). than in data folder all the emmc data

thanks at all of you,but i knew already this method,i want to know if it s possible to read a folder in my laptop because randomly the other day i connected my phone to my friend laptop and opening the file manager i saw his laptop . . than s way i m asking because i want to do the same with my laptop.

why not use wizard mounter and mount a folder on ur laptop.
i use it and ubuntu and windows share mounts fine.
windows share is really slow in default file manager though for some reason but i use midnight commander to browse the network and works a treat.
