How can I send large files from my device to my computer, without using a cable?
If your remote pc has Linux, you could do it through scp command.

See here an explication of the command. You could run this command from a terminal emulator like this one.

Short example:
scp -r path/to/folder user@remote-PC:/path/to/where/to/save/the/filesscp path/to/file user@remote-PC:/path/to/remote/location/where/to/save/file* -r option means recursively copy entire folder.

If your remote pc has windows, take a look at pscp.



Another way is to install ES File Explorer File Manager. * Select the local files you wish to transfer (actions -> copy) * In LAN section access a folder from your remote PC and paste (actions -> paste) the selected files.* The folder from remote pc has to be shared with write permission.
