TeraCopy 3.0 alpha

December 30th, 2014 56 comments

Feel free to test this new alpha version:

  • Faster copy, especially to/from network locations and with small files.
  • Single tabbed interface for multiple file transfer operations.
  • Copy files using elevated Windows Service and Volume Shadow Copy.
  • Unlimited number of files, the internal file list stored on disk instead of memory.
  • Create MD5 checksum filelist after copy.

Not present in this version: moving and deleting files, displaying/editing file list, overwriting files.


Note: Temporarily removed auto-install of TeraCopy Windows service due to false alarms of antivirus software. If you want to try it, please run TeraCopyService.exe /install in Admin mode.

Upcoming TeraCopy 3 features

December 12th, 2014 52 comments

A new version of TeraCopy is currently being rewritten from scratch. The goal is to make it faster and more extensible. Planned features include:

  • Unlimited number of files, keep file list on disk instead of memory.
  • Immediate start of copying instead of waiting for calculation of total files size.
  • Verify copied files with MD5/SHA-1 instead of CRC32, option to create .md5/.sha file list.
  • Show file list as browsable folders, show only failed files.
  • One window for multiple file transfer operations.
  • “Save bandwidth” mode

TeraCopy 3 beta is expected to be released early next year.

Update from December 7:

The new copy engine is ready and shows a good speed with both large and small files. Testing was done with a single 8 Gb file and 9 000 small files (300kb in size). In both cases speed was on a par or slightly faster than in Windows copy. MD5 hash calculation was on during the large file copy. Small files copying speed improved a lot after disabling Windows Defender.

Update from December 12:

TeraCopy now can avoid UAC prompts while reading files usually requiring elevation. This will eliminate possible ‘access denied’ errors in a middle of the copy process. For security reasons this feature will be available only to non-elevated administrators, users with a ‘standard account’ will still be required to start TeraCopy with admin privileges.

Update from December 17:

Copying using Volume Shadow Service is ready. Used usually in backup applications, it allows you to copy files locked by other applications.

TeraCopy 2.3 beta 2

December 30th, 2012 66 comments

  • Added: Additional check for trimming file, useful on D-Link NAS devices.
  • Added: ‘Confirm drag and drop’ option.
  • Fixed: Removing files from filelist when not enough disk space.
  • Fixed: Skip button now works on error files.
  • Changed: Flashing window instead of tray notification.


TeraCopy 2.3 beta

January 30th, 2012 84 comments

What’s new:

  • Added: Choose between TeraCopy and Explorer on every drag’n’drop operation.
  • Added: Moving files within the same drive without launching TeraCopy.exe.
  • Added: ‘/Report’ command line key.
  • Fixed: Problem copying some locked files.
  • Fixed: Unnecessary verification of skipped files.
  • Fixed: Conflict with Google Chrome on Windows XP.
  • Fixed: Dropping files into TC window now possible in Waiting mode.
  • Fixed: Use %UL instead of %L in Total Commander buttons for Unicode support.
  • Added: Resolving linked network folders to real path on Windows XP.
  • Added: Option CopyCreationTime to ini file.

Probably fixed VMware problem as well. Please use carefully, it’s not fully tested.


Update: to reactivate the new drag’n’drop confirmation dialog in this beta version, set parameter ConfirmDrag to 1 in HKEY_CURRENT_USER\Software\Code Sector\TeraCopy with Registry Editor.

A rather useful tip from Andy Malcolm, you might want to test it, even if you have another AV:

Just a quick note to recommend that you suggest to your customers that they list teracopy.exe as an exclusion in Avira Antivirus on-access scanner. The reason being that I noticed full CPU usage when using your product with Avira and it was the Avira process wasting cycles, when I excluded your program from avira on access, your program, which had been somewhat unstable, started copying files 8 to 10 times faster than it had been before, my CPU usage dropped off to a more reasonable level and it seems to have resolved stability issues.

TeraCopy Portable

Version 2.27 was updated the server with a new installer – now you can easily install a portable version as well. Just point the installer to your flash drive and select ‘Portable version’. Start menu shortcuts will not be installed and no changes to registry will be made. This also means no drag-and-drop integration.
