For data sharing,
C:\users\Public is /sdcard/c in YouWave's Android
In your Gallery, you will see pictures in your C:\users\Public directory. You can copy your pictures to that directory and send them out through apps like WhatsApp.
For example, to copy out the pictures and videos that other people sent to you through WhatsApp, use "Open Manager" app, explore to /sdcard/whatsapps and your files are in one of the sub-directories. Copy a file and paste it in /sdcard/c directory. The file will be actually copied to your C:\users\public in your hard drive.
To copy a file in "Open Manager", long click the file, then click "copy" at the top. To paste a file into /sdcard/c, go to /sdcard/ then long click "c" directory, then click the "..." at the upper right corner, choose "paste". Now you have copied the file to your C:\users\public directory.
