    Copy Files Conflict: Overwrite Older Files ala Teracopy


    I've been using Teracopy since Win7 and when it encounters file conflicts, it gives you the option to overwrite older files automatically or with the press of a button. The Win 8 copy dialog allows you to compare files and skip those with the same date and size. There is copy and replace option but I do not see one to replace if file is newer or skip if file is older
    Click image for larger version

    1) Is there an option similar to the Overwrite older or do you just have to compare files individually?
    2) When it says same "date" does it just mean the day or is the time accounted for as well for example if I had a file that was updated a few hours after the original, but on the same day, would it recognize that as a difference?

    PS: Has anyone done a side-by-side comparison of Win 8 copy vs Teracopy?

    In Teracopy, when it detects one or more dupe files that are in the destination, a dialogue box will pop up giving you a choice to either copy over or rename and for a single instance or multiple instances. I usually tell it to "Skip All". It checks the files for Names and Sizes, and if a file is exactly the same in name and size and date, usually Teracopy skips it by default. This is because you can resume a huge copy process started in Teracopy if it gets interrupted: You can resume such a copy process by just dragging the whole folder over the half-copied destination, then Teracopy checks all the files and blanks out the ones that are already copied.

    In the case of what you showed up in your pic, I think Teracopy may have skipped that file by default, only copying the ones that are not already there. But if it gives you a dialog box, just choose "Skip All". I'll have to check it's behaviour.

    Teracopy is better for copying a folder with a bunch of sub folders from one drive to another. I use it to copy a Data Set that's about 500 GB in size: Working with a file set of that size, Teracopy is the best way to do it. If you want to not use Teracopy for local copying of a few files, right click on the folder to be copied and drag it over to the destination. then release the mouse and in the selection popup, choose "Copy" and not Teracopy. There will also be a "Move" and Teramove selection as well.

    By default, Teracopy takes over the regular single left click copy and move functions of explorer. Normally, this is not an inconvenience, unless you are tampering with protected System folders. In that case, you need to use "Unlocker" for copying to certain system folders.

    Thanks for sharing your Teracopy experience. The pic above was actually from the default Win 8 copy dialog. And is Unlocker working in Win8?

    The Unlocker Program works, but the installer has a bit of Malware in it, it wants to install "Delta Toolbar" which is a nasty bit of programming. This can be avoided by choosing "Custom Install" and de-selecting the toolbar.

    The toolbar makes most AV programs detect the whole installer as malicious, and it is blocked by Malwarebytes and Eset NOD32. But I guarantee you, the Unlocker program itself is safe. You have to add the Installer into the list of allowed programs for Malwarebytes and Eset - Just don't install the Toolbar.

    I've used Teracopy a lot, and for very large blocks of data it is the best. One of my computers was locking up randomly in the middle of a Teracopy process, and I was able to resume it and carry on from where it had been interrupted. You just have to repeat the same Copy actions, for instance if you dropped a huge folder into a subfolder on another drive, and it gets interrupted just do it again exactly how you did it the first time, and then it will simply resume from where it was interrupted.

    Funny enough, I contacted the developer of Unlocker a few years ago and told him that his product had adware in it (I think NOD32 marked it as you said) and he flat out denied it. I swore off the program after that. I'm glad to see that the Delta toolbar is optional, as long as you pay close attention to the install.
