How to speed up file transfer between two computers
HTML-код
- Опубликовано: 9 авг 2022
- This command is really useful when you are transferring a large amount of files. It not only helps you transfer files between different computers, but also helps you transfer files between hard drives on the same computer, between the computer and an external storage device.. This command is available on Windows operating system and you do not need to install any other software

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 .
Can you please elaborate using MD5 checksum.
I expect your more videos ... You are very intelligent man thanks for sharing your knowledge with us
So nice of you
Thanks for this great tip !
I have just been following your videos recently and found it is highly usefull. Thanks for sharing knowledge with us..
So nice of you
Thank you so much for all the work you do
You are so welcome
It is not a valid test. Data was cached on the second copy.
More than probably (cached) because there is no reason drag/drop takes much longer than CMD action. Actually, I tested two methods. Found exact same time in two methods.
I don't understand why there was no report and no person who tested as what I did.
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 !

Awesome sir thanks for sharing ❤️
Thanks and welcome
Awesome Sir
If you use multitheading copying files, will they be fragmented on destination disk?
Are you sure that the read/write operation have been completed at the time of command prompt return, rather than just being backgrounded?
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.
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.

Bagus, belajarlah juga mengenai sifat baik anak ini yang membagi ilmu kepada siapa saja dari suku dan agama manapun di dunia. Indonesia perlu belajar sifat yang baik dari orang lain....
*THANKS*
Welcome
Great~!!!
Thank you! Cheers!
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 ....
Btw: great video, and there's more commands like this, and i've found out that many "sysadmins" doesnt know about this command !!!!
I think they make only BAT files with simple copy commands in it ... from one drive to antoher ....
@@kokikocky4319 I use RoboCopy scripts with variables to make things easier and keep track as I use it to backup several servers nightly.
Thank you so much😀
very nice
Thanks
Good bless you
can we transfer specific date files alone using same command.
NICE
Thanks
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?
This requires a network to be used. If you have 2 computers both connected to the same internet modem you basically already have a network.
If you follow the steps as shown in the video you should be able to do this too. Just make sure you use the IP address shown on your own computers in the commands. ;)
Although robocopy can also be used to copy between 2 drives in the same computer... it's not really a good thing to use this to copy to a USB drive as USB drives usually have limited speeds for writing and the multiple threads used by robocopy will more likely hurt your speeds instead of improving them.
Unless one of the two ports is OTG. It won't work and damage 1 of the computers. Besides usb to usb is slow as shit. Get a reversing cat 5 and go gigabit Ethernet. All the setup rules apply for Ethernet, (assign ip, framesize etc...) A good Ethernet setup can see 500-900 MB/Sec. That's megabyte not megabit.
is this possible on linux (fedora/ubuntu) please.
Perfect
The time in which i will write this command my files would have already been copied through drag and drop😂😂
Thanks for sharing this!
Does this command only work with IP address or with the computer name?
Both
it works with IP addresses unless you have a working domain, workgroup or something setup for your hosts to know each other. so yes, it can work with hostnames if you have set them up properly, otherwise it will always work via IP
I want to copy files from external hdd to internal ssd any fast way to copy large file of 100gb
Hi Can you please make video on copying files from windows to linux pc
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.
But please tell me how to transfer files from windows 10 pc android phone in this much of speed
It is not sense, due to a different protocols? so when drag-n-drop uses SMB, and command line - SCP
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
I stopped using ES Explorer a while ago and now I'm all in Mixplorer, I really recommend it. It has the option to create an FTP server that you can then connect from any other device. Just be careful that FTP is really unsecure, but for your home usage should be fine.
Also, lately I've been using Syncthing to maintain synced folders between my different devices.
Both tools are open source and well known.
@@DavidCastillaGil Thanks for the information 🙏🏿
Thanks for this tip
It is possible to do the same on Linux ?
sure, in Linux you're probably looking for rsync tool, or just the standard cp and mv commands.
What is M32 in Cmd...🤔
Can I use any Number instead of it....
Example.I want use M36 ,M64 ,M100 like this...🤔🤔🤔
Did you found out ? He mentioned that
Brother any tip to speed my internet speed in Android.
We need a way to recover deleted files

Is this faster than TeraCopy and/or FastCopy?
Nice thing about RoboCopy is it's already installed in Windows. Just run it and boom you're done.
Robocopy might be faster* than Teracopy as robocopy can use multiple threads (default is 4) where as Teracopy uses 1 thread.
Fastcopy does appear to allow multiple instances, but that's only for multiple jobs. I don't see Fastcopy having multiple threads available.
* it does depend on the drive hardware you read from and write to if it can handle 'high drive operations payload'. 😉
@@usulatreides863 Thanks for reply. I try both few days,, if there are many small files, robocopy is much faster. however my major speed limit is daily backup abou 100+ 5GB-10GB video files to NAS (via 2.5Gbe ethernet),, in this case multiple threads acture slow down the copy speed. So now I mix use both.
@@MJLee-wl6kt The high number of threads in robocopy is nice when dealing with a big number of small files. For larger files sticking to the default of 8 might be better or test using only 4 threads even ;) .
1 thing to note about robocopy is that it doesn't show the number of active threads. It just looks like it's running 1 active thread.
Yeah im curious also
What meaning MT:32
Like
How many copied files will be defragmented?
Robocopy will not prevent copied files get written fragmented.
I copied 90 GB to another PC using this method , It's more than 24 hr so far and still not finish ... . really work ?.
Warum braucht das "Standard Kopieren" denn 3. mal so lange?? 🤔

How to make batch file using this command.
i will try
Excellent question 👍🏻👍🏻👍🏻
Why needs for batch file? Its better to automate some things by making batch files with strict command in it ...
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 ?
Bullocks, I've tried fast coping with your shown command and with no expected result!
SFTP
M:32 M:128 what does it mean? Can you describe
This defines the number of copy threads. The number is the number simultaneous copy threads.
/MT:32 would mean that 32 separate copy threads are used.
This is only useful if you a really high number of files to copy though.
Default is 8

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.
For more usage information run ROBOCOPY /?
Same to you bro!
Check your slashes, in Windows all paths have the backslash \ while the parameters for commands use the normal division sign /
You have to use ROBOCOPY /S C:\source\folder \\destination\folder
note the S parameter has the / while both paths use \
You didn't provide the actual command string you used, but... by going what you typed in the error it is likely you should have used:
others D:\test /mt:30
(spaced out and a : in the /mt operator)
Filezilla is better
