How to speed up file transfer between two computers 

I use this command in a script to distribute builds ( more than 1 gigs ) to several workstations as part of scheduled tasks overnight, since years now. Developers should script all their repetitive tasks for more efficiency . I also suggest using MD5 checksum to make sure file transfer didn't corrupt any file here and there after compressing the whole thing .

I tested with 80GB transfer between D:\ and E:\. Both are within a same computer, and RAID 0 NVMes. D:\ = RAID 0 of 500GB + 500 GB. E:\ = RAID 0 of 1TB + 1TB. The D:\ is a drive on which I work, and the E:| is a backup after I work on D: Results = same using the CMD and Windows10's drag/drop. The speed of the two tests were, don't be surprised, 2,700MB/sec for both. 80GB = 80 giga-bytes (not giga-bit). File transfer speed = 2.7GBps = 2,700 Mega-byte per second !

I expect your more videos ... You are very intelligent man thanks for sharing your knowledge with us

It is not a valid test. Data was cached on the second copy.

I have just been following your videos recently and found it is highly usefull. Thanks for sharing knowledge with us..

Dont use /S it's better /E, couse with /S robust copy will copy subdirectories, but not if its empty, it wil skip it ... There's more usefull options ... Type "robocopy /?" (Without qutes to see more options for Robust File Copy ... ) very usefull command, but if you dont know how to use it, better stick with drag'n drop ....

Said twice before. I will say it again. The destination computer will fragment all the files. All the time saved is multiplied exponentially on wasted seeks on reading that data. Read,move,read,move,read,move,read is much slower than read,read,read,read. A un-fragmented file is taken as just one long read. If you are going to argue an SSD has no seek time. A fragmented file on SSD still requires processing through the device driver on every move. A mechanical drive requires moving between tracks, which is minimized by read ahead in the drive. Which occurs if you are read 1 sector or more. The drive will read the one sector request and cache more tracks ahead (all occurring asynchronously of the PC). A large cache on a fast Sata drive is a must.

Are you sure that the read/write operation have been completed at the time of command prompt return, rather than just being backgrounded?

Elizandro Rodrigues de Mello is correct, the files on the destination PC copied using the 1st method aren’t actually wiped from the drive, they are simply marked as deleted. Although your suggested method of transfer could be faster if comparing USB 2 and Gigabyte LAN.

Seems to work reasonably well when you want to copy an entire directory. Not very practical though if you only want to copy a half dozen files out of a directory containing many files.

The time in which i will write this command my files would have already been copied through drag and drop😂😂

いつも有意義な動画をありがとう！ 動画を見ていてとても面白いです！

Thank you so much for all the work you do

Thanks for this great tip !

terima kasih pak.. saya dapat ilmu baru lagi.. salam dari kota baubau, indonesia

Awesome sir thanks for sharing ❤️

What is M32 in Cmd...🤔 Can I use any Number instead of it.... Example.I want use M36 ,M64 ,M100 like this...🤔🤔🤔

I'm unfamiliar with sharing folders on 2 different PCs; I assume you just use any old USB cable to connect the two, but what command(s) must you issue after that so the source PC can view the target PC?

Awesome Sir

Thanks for sharing this! Does this command only work with IP address or with the computer name?

*THANKS*

If you use multitheading copying files, will they be fragmented on destination disk?

But please tell me how to transfer files from windows 10 pc android phone in this much of speed

I want to copy files from external hdd to internal ssd any fast way to copy large file of 100gb

can we transfer specific date files alone using same command.

Hi Can you please make video on copying files from windows to linux pc

Thanks for this tip It is possible to do the same on Linux ?

Brother any tip to speed my internet speed in Android.

It is not sense, due to a different protocols? so when drag-n-drop uses SMB, and command line - SCP

I copied 90 GB to another PC using this method , It's more than 24 hr so far and still not finish ... . really work ?.

Perfect

What meaning MT:32

very nice

Good bless you

is this possible on linux (fedora/ubuntu) please.

Warum braucht das "Standard Kopieren" denn 3. mal so lange?? 🤔

NICE

Great~!!!

Thank you so much😀

Bullocks, I've tried fast coping with your shown command and with no expected result!

Anh dùng phần mềm gì để nói tiếng anh vậy

Is this faster than TeraCopy and/or FastCopy?

How many copied files will be defragmented?

We need a way to recover deleted files

I use es explorer to copy file from pc to mobile but it doesn't transfer more than 100kb data. So i use data cable which is very annoying. Any help? Thanks

Not working

Not speed with me🙄

Rtx 3070 ti Crashing Hi , I have recently started mining. Rtx 3080 LHR X 4 Rtx 3070 ti X 2 Nicehash (dagger/NBminer) Everything running smoothly, until: 1 of the 3070ti keeps turning off after 30 min. Lowered overclocks, and then started turning off after 12 hours or so. It completely shuts down the power supply as well. Restart the computer, turn the card off and on and then runs for another 12 hours and does the same again. I've tried to replace the riser, I've changed positions using another riser slot and still the same issues. Card was used by a friend over the wknd and ran for 48 hours with no problems. This afternoon it keeps giving a: Cuda error: out of memory (err_no=2) Device 4 exception, exit ... Any help ?

🙏🙏🙏

M:32 M:128 what does it mean? Can you describe

I waste my time just to see this.

I got this below error ERROR : Invalid Parameter #4 : "othersD:\test/mt30" Simple Usage :: ROBOCOPY source destination /MIR source :: Source Directory (drive:\path or \\server\share\path). destination :: Destination Dir (drive:\path or \\server\share\path). /MIR :: Mirror a complete directory tree.

Filezilla is better
