How to use adb command to push a file on device without sd card

I did it using the push command, which has syntax:

adb push filename.extension /sdcard/0/

Example of copying directory, and sub-directory content:

adb push C:\my-location\data\. /storage/emulated/0/Android/data

Note that push did just hang in latest platform-tools (33.0.1, at time of writing) for a certain amount of files, beside the adb.exe suddenly taking 5MB+ instead of 1.5MB, hence I just did replace the adb.exe with one I had from 28.0.0 version of platform-tools (I did not downgrade the entire platform-tools, because adb.exe is kind of stand-alone).

I don't say there is any conspiracy around data folder,

But my Samsung device puts limits on my USB file transfer, beside Android v11+ not allowing access to data folder anymore, hence I needed above command to work with 100% speed (without hanging one hour for little more files).

Follow these steps :

go to Android Sdk then 'platform-tools' path on your Terminal or Console

(on mac, default path is : /Users/USERNAME/Library/Android/sdk/platform-tools)

To check the SDCards(External and Internal) installed on your device fire these commands :

• 1) ./adb shell (hit return/enter)
• 2) cd -(hit return/enter)

now you will see the list of Directories and files from your android device there you may find /sdcard as well as /storage

• 3) cd /storage (hit return/enter)
• 4) ls (hit return/enter)

you may see sdcard0 (generally sdcard0 is internal storage) and sdcard1 (if External SDCard is present)

• 5) exit (hit return/enter)

to come out of adb shell

• 6) ./adb push '/Users/SML/Documents/filename.zip' /storage/sdcard0/path_to_store/ (hit return/enter)

to copy file

From Ubuntu Terminal, below works for me.

./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/'
