You can use the adb push command to copy files from the local workstation to the Android device. The following is the syntax for using this command:

adb push <local> <remote>

<local> refers to the location of the file on the local workstation and <remote> refers to the path on the Android device where the file needs to be stored. For instance, the following command-line output shows filetest.pngcopied from the computer to the Pictures folder of an Android device:

adb push C:	emp	est.png /sdcard/Pictures
[100%] /sdcard/Pictures/test.png

You can only push the files to those folders for which the user account has privileges.
