I have a gaming laptop and a phone, both of which have USB 3.2 Gen 2 and Gen 1 ports. I also use a USB 4 Type-C cable. Now, recently, I have downloaded music files of over 300GB. If I transfer them one by one, it takes a lot of time. Today, I compressed the folder to a single zip file, and the transfer finished in less than 20m. Why is that so?


Do you use any GUI program for this or just plain old cmd?
Adb is a command line program. To copy your music folder from home on your PC to internal storage on your phone, you would just open a terminal abd type
adb push ~/Music /sdcard. Pressing tab will autocomplete folder and file names. For some reason/sdcardon android is actually the internal storage. If you have an SD card, it will be in/storage/card_name, where card_name is the UUID of the partition on the card.You do have to enable USB debugging on your phone before you can use adb to transfer files though.
