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?

Understood. I’m also talking about sending a full zip over to the flash drive, then unzipping it on that same flash drive.

Music files are large enough to not get affected by overhead like sending a ton of 1kb files. I see no significant difference in transfer time sending 100 10mb files or a single 1000mb file.

This is a totally different story with actually small files (ie kilobytes). Music downloads are not small, they’re multiple megabytes.

Well if you're unzipping on the flash drive, that's a whole mountain worse than copying device to device. Why would you want to torture the flash drive and your patience like that?

Right… that’s what I’m saying! My entire point.

Sending a zip of music files to a phone, then decompressing that zip on the phone, seems like a really stupid idea to me. You’ve now set up a situation where you’re reading and writing to one drive rather than reading from one and writing to another.

I feel like you are suggesting they would decompress the file over USB from the computer after it is transferred, and not use the phone to decompress it after it is transferred... Once it is transferred to the phone, just use the phone to decompress it.

No, that is not what I am suggesting at all.

Decompressing the zip on the phone is an inefficient operation, as you are reading and writing to/from the same storage device. It’s much more efficient to forgo the zip altogether and just transfer the files from one device to the other. No zipping whatsoever.

As said in other comments, it’s MTP that’s the issue here. Just use USB mass storage. MTP blows.

Did we forget MTP is specifically what was being discussed?

[–] deranger@sh.itjust.works 2 points 6 days ago* (last edited 6 days ago) (1 children)

I don’t see that specified anywhere, just looked at OPs history. MTP blows. Surely that’s not the only option on Android these days?

It sure is

Edit, looks like someone at least made an ADB version https://github.com/T0biasCZe/AdbFileManager
