TeraCopy v3.26

billon on 15 Oct 2017
  • 13MB (uncompressed)
  • Released on 14 Oct 2017
  • Suggested by AntBond

TeraCopy lets you copy or move files at the maximum possible speed. It uses dynamically adjusted buffers to reduce seek times, as well as asynchronous copy to speed up file transfers between two physical hard drives. When an error is encountered during copying/moving, TeraCopy will automatically retry and skip the files that cannot be transferred instead of aborting the entire operation. It also shows failed file transfers and lets you recopy only problem files.

Once the destination directory is selected, files can be dragged-and-dropped onto the window, even while a transfer is in progress. Once files are transferred, the Verify option uses a CRC check to see if files are identical.

System Requirements: Vista / Win7 / Win8 / Win10
Writes settings to: Application folder
Stealth: ? No. Creates some files in the user folder.
Unicode support: Yes
License: Freeware
How to extract:
  1. Download the installer and launch
  2. Choose the destination folder
  3. Select "Portable version" and uncheck the option to "Associate with checksum files"
  4. Launch TeraCopy.exe

This is one of the few programs I keep on my flash drive in my _sys_exts folder. I install this on almost every computer i touch. I'm almost 100% portable with this as one of the VERY few exceptions. It's invaluable for moving large groups of files and the shell context menu integration is a must.

I've not toyed with portable shell integration. i use cafe to do all my file launching. Any suggestions on how to get the context function portable would be appreciated.

I wasn't sure which one to download so I picked the "portable" version. AVG has warned me that teracopy is infected. Surely a false positive, but I seldom have this happen. There's the off chance that the file has actually been infected, but I doubt it. I'm updating as of now to see if this remedies the situation.

a 2009-09-11 14:20

No sir. Still says its infected. A little vague. Does "SHDOCVW" or "Win32/Heur" ring a bell to anyone? AVG knowledge base gives no information.

Webfork 2009-09-11 15:34

Lifehacker LOVES this program and I can see why.

"Heur" means a "heuristic" virus detection, or a possible detection, not something based on a documented virus. If you Google it, you'll see that it probably has something to do with the SHDOCVW.DLL call.

Anyway the program comes up clean on both ClamWin and Comodo AV, which are usually much more paranoid than AVG (see MailPV and Produkey).

Queue 2009-09-11 16:56

Personally, I've found AVG to be one of the most paranoid and false-positive-heavy AV scanners in existence.

FastCopy is a smaller alternative to TeraCopy.

TeraCopy's basically the gold standard in this category however.

Jerry Chrane 2009-09-13 07:56

Weighing in on the AVG detection of a virus in the portable version, AVG did report an infection as well as Drive Sentry reporting suspicious activity and virus behavior. I'd have to recommend that this product not be downloaded or installed.

Queue 2009-09-14 20:06

Out of 41 virus scanners, 6 came up with heuristically detected positives (oddly, AVG WASN'T on the list when I checked). This is a little higher than normal for false positive detections, but still very indicative of a false positive. However, this isn't that odd for a program like this: it bypasses standard system file copy routines and uses other various tricks to achieve as good of file copying speed as possible.

Ignoring that intelligent malware doesn't use tricks like this because it will get them caught, I can't stress enough that knowing how to evaluate anti-virus detections is more important than actually using an anti-virus/malware scanner.

This program isn't malicious and it isn't ''infected'' with anything.

p3ngwin 2009-09-26 09:16

i too would love to know if it's possible to install onto USB drive and have the context menu options.

AntBond 2009-10-30 12:07

I always use ESET because it has less false positives and detect almost every virus or trojan.

BGM 2009-12-06 20:40

It might be possible to add portable context menus with PowerPro portable. It has the ability to add things to the windows explorer menu. Another alternative might be to temporarily add a registy entry to the * for all files, and then delete the key on removal of the drive. You can do this with PowerPro. I use Powerpro to add a reg key to open all files with Notepad2, and then when I close my powerpro, the reg key is deleted.

Mike S. G. 2010-01-19 12:53

I'm not sure if the info posted on TeraCopy (How To Extract) is dated but the latest version 2.12 is an Inno setup and not a self extracting exe. The last version stated as portable is 2.05 which I can't even find the download link, I just downloaded it a month ago but it looks to have been taken down.

Regardless, TeraCopy is an excellent app for anyone who moves files on a regular basis, and wants the added benefit of speed and verification of a successful move (or copy).

Mike S. G. 2010-01-19 15:46

Follow up:

Thanks for updating the information.

BTW, I must be blind as a bat, the link to the portable is right there on their site (still 2.05 / but there). :)

bassiliin 2010-01-19 17:43

File named "Portable" (without extension) in app's folder keeps settings in app folder

Portable Paul 2010-01-22 07:36

i love the context menu option of this program, the only way to get it integrated into the shell is to use one of the portable explorer replacements. i'm sorry i can't remember which one but it's one that's on portableapps.com

donald 2010-06-15 18:51

Please note there is a portable download from the application homepage.
The download is in a .paf extension installer and may not extract directly to a hard-drive.

Kermode 2010-09-11 16:11

Doesn't allow you to queue copy to several different destinations.

Kermode 2010-09-11 17:14

And it doesn't even work very well. I set it to move a lot of files from A to B and when it said it was "finished" most of the files were still left on A so I had to return to using damn Explorer - tsk tsk.

spicydog 2011-03-12 18:47

Please take a look at this thread http://www.portablefreeware.com/forums/viewtopic.php?f=5&t=8168&p=31997 (#p31997) and if you have any idea let me know.

Version 2.2 is out using the direct like below.


Magibon 2011-11-24 16:33

A new installer for v2.7 has been released.

the installer will give you the option to install as "Portable".
* drag & drop feature will not be available

CRC-32: 303ff877


abc 2012-06-23 01:32

I've was able to copy about 10 GB of files from an aging and extremely noisy and slow hard drive via a USB adapter -- Would have gotten a head ache had I copied from windows explorer, or tried to. PS. 0/42 flagged by virus total, it's clean. PSS. Development seems to have slowed down but there's a beta floating that adds some features / fixes some issues.


spicydog 2013-01-09 12:04

As of v2.3 (despite I use it in the portable mode) TeraCopy stores its license in the user's appdata folder... Can anybody suggest a way to force TeraCopy to store its license in the same directory where TeraCopy.exe is run from (just as it was in previous versions)?

Despite it is a beta I have been using v2.3 (now at beta 2) for a while and I found it to be very stable and reliable.

Over a year ago I have requested the developer to introduce a specific feature and since it has been (finally) implemented in v2.3 I prefer to avoid previous versions... I just do not understand why they changed the location where the license is stored from the application folder to the AppData folder!


spicydog 2013-01-09 12:09

Actually I just realized that I requested that feature almost 2 years ago... Time flies, fellas ;)


kac0802 2013-02-11 22:38

The following should work (got info from http://en.kioskea.net/faq/9814-portable-minecraft-minecraft-on-your-usb-key you can look at it if you need clarification of following instructions):
---- create a folder in the same folder as the exe named "data"
---- open Notepad and type:
set APPDATA=%CD%\data
---- save as portable_TeraCopy.bat (or whatever you want to call it. just make sure it still has a .bat extension)
---- make sure Notepad did NOT save it as portable_TeraCopy.bat.txt
---- optionally use Bat to Exe Converter (http://www.portablefreeware.com/index.php?id=1660) to make it an executable
---- run the bat (or created exe) to run TeraCopy and it should save anything it would save in the user's AppData in the data folder you created instead


kac0802 2013-02-11 22:46

PS: I haven't tested the above to ensure it works, but it should work in theory.


joby_toss 2013-02-12 13:02

@spicydog: what license file?


spicydog 2013-02-15 14:13

@ kac0802: I wish it would have worked, but thanks anyway for your suggestion.

Also please consider that I mostly (as in 99.9% of the times) control TeraCopy via ctrl+C and ctrl+V so even if the batch trick would have worked, to implement a suitable workaround it would be quite complex.


spicydog 2013-02-15 14:17

@ joby_toss: The license file to use TeraCopy as Pro rather than free... Since the introduction of this new version I have been using TeraCopy without the license so it runs as freeware.


spicydog 2013-02-15 14:18

If anybody finds out a working solution, please PM me :)



Midas 2013-02-15 15:15

As a fellow Teracopy user, my guess is that you'll have to portabilize the install version with a launcher...


joby_toss 2013-02-15 17:38

@spicydog: Oh, I only use the free version (like the majority of TPFC users), so I think only Code Sector can address your issue.


spicydog 2013-02-17 09:22

@ Midas: I still hope that in a never version TC will return to the previous default behavior, if not I will just continue using it as freeware

@ joby_toss: You are probably right mate but they are so bloody unresponsive


Peter202 2013-07-18 12:33

The instructions are very poor!

First: in extracted files there is no TeraCopy.exe file.
Second: This new folder where should be created and how to name it?

Please, clarify!


Midas 2013-07-18 13:53

@Peter202: if you use Universal Extractor (RTFM, please), TeraCopy.exe is located inside the {app} folder in extracted path; you can create the new folder wherever you prefer, and give it whichever name you like, as long as you remember those and it works -- that's the beauty of portable.


Peter202 2013-07-18 18:31

When i try to extract the files with Universal Extractor it gives error:

Signature detected: Inno Setup Setup Data (5.4.2)
This is not directly supported, but i'll try to unpack it as version 5309
; Version detected: 5402
Critical error: The setup files are corrupted. Please obtain a new copy of the program.
Unpacking failed. This version is not supported.

With 7zip i can extract the files, but there is no app folder. These are all extracted files:



JohnTHaller 2013-07-18 19:07

TerraCopy can only be opened with one of the unofficially updated Universal Extractors. Either the one Lupo did or the illegally updated one that didn't release the source code will work as they include the updated InnoUnp.exe. It won't work with Universal Extractor 1.6.1 base version or 7-Zip.


JohnTHaller 2013-07-18 19:12

You can also just run Inno Unpacker on it directly. Grab it here: http://innounp.sourceforge.net/ And just place innounp.exe and terracopy.exe in the same directory and run innounp.exe -x terracopy.exe from the command line. That's all Universal Extractor is doing under the hood after it figures out what kind of installer it is.


Peter202 2013-08-25 08:57

How can i set TeraCopy is default copy program instead of windows explorer? In application folder there is one reg file DefaultHandler.reg but if i open the file and add the registry value to the registry it still doesn't change to default copy program.


hamasaki 2013-10-22 19:18


Great help, thank you. Just one thing, its teracopy, not terracopy. Hence the command line example was slightly wrong.


joby_toss 2013-12-08 17:52

@Peter202: you need to adjust the paths inside that .reg file accordingly.


finiderire 2014-07-26 12:00


I can't find Teracopy Portable.
When I run the downloadable executable it runs an installer which ask for Program Files (which means, not portable).
Thank you for you help


Configuration :
Teracopy Portable Version 2.0 beta 3
Windows 8.1 Pro x64


finiderire 2014-07-26 12:02

Hi again,

Read this :
" Download the installer and extract.
The application files are in the {app} folder.
Rename Portable.txt file to 'Portable' (remove .txt)."

SO let's change my question : why not providing the program as a Zip file already "prepared" ?

Launch TeraCopy.exe.


finiderire 2014-07-26 12:05

Hi again,

This did not even work, no app after Extract (using 7-ZIP Portable).

Let's say I forget this app forever.



I am Baas 2014-07-26 13:35

"Let's say I forget this app forever."

Good. Can you forget this Website too?


Checker 2014-07-26 13:41

@ finiderire: The word 'extract' at the 'How to extract:' is a link to an application called 'Universal Extractor'.
Use this to extract the installer file and follow the rest of the 'How to extract' instructions.


webfork 2014-07-27 19:55

finiderire: "why not providing the program as a Zip file already "prepared" ?"

We are just listing this; we didn't develop it. Feel free to contact the developer at the "website" link and ask. The method that we have is a trick that enables portability on a great many terrific apps. Please see the site FAQ.


BottleOfWater 2015-03-24 21:26

I feel as though the size of this application is incorrect. Even after deleting all unnecessary items the size of my TeraCopy is still 3.35MB. Is there something that I am missing?


Checker 2015-03-25 03:26

@ BottleOfWater: Thanks ... and corrected ;)
