Send files from one mobile to another (Android)

Send files

When you two Android devices on the same wifi network, a simple solution is available to transfer files between them: ES File Explorer File Manager. (Note that there are other products by the same company with similar names, so use the link.)

• Install the app on both mobiles and launch it on both.
• Browse to the required (source) folder.
• Long press to select one or more files (or folders).
• Select Send to send the files to another mobile.
• Accept the request on the other mobile.
• Select the folder to save the files in.

This solution does not require you to turn on/off settings, use the cloud etc.

File/folder synchronization

If you are after synchronization between devices, take a look at the Android app SyncMe. While this app is highly rated, it has an issue in Lollipop - when synchronizing with a remote folder that has a new folder, it cannot create a (matching) new folder in the local SD card. This is due to changes that were done in Android with respect to writing to an SD card. The developer apparently has to rewrite quite some code and test it thoroughly - he's working to fix the issue.
