The lightest, fastest FTP server that allows you to connect to your phone over wifi to upload and download files. Any FTP client can be used. File explorer and Web browser also can be used.

Some of the similar tools are SwiFTP Server, Wireless File Transfer Pro (using this you can remote instal apps also) and a much larger , Wifi File explorer. Using the last one you can only download files as zipped versions.
Now they have another app, by which you can share the whole of memory card or just one folder and with password protection to safeguard the files. This app is about 260 kb only.

Eshare
This is another app and though slightly bigger size ,looks a better and stable one with a better GUI, WiFi File Transfer . It is possible to transfer files both ways with this app. ( However this app has a restriction of uploading file size only upto 5MB to the android device, for which you have to go for the pro. Otherwise there are no limits)
