FIX: Calculating the time required to copy the files error

2. Check storage for errors

windows 10 error the current active partition is compressed
  1. Type cmd in the Windows Search bar.
  2. Right-click on Command Prompt, and run it as an administrator.
  3. In the command line, type the following command and press Enter:
  4. If your system partition isn’t C, replace c: with an alternative letter assigned to your system partition.
  5. Restart your PC, and try copying files again.

Now, the aforementioned steps should help you speed up the copying process substantially, but the prerequisite condition is a fully functional storage.

If your internal/external HDD or USB are damaged or corrupted, the calculation and processing files will take a lot more time than needed.

In the worst case scenario, you won’t be able to manipulate files at all. This is a clear sign of the upcoming HDD failure, and we recommend backing up your data as soon as possible.

But, what we don’t want is rushing to conclusions. Instead of that, you have various ways to check the storage for errors.

There’s a lot of tools for doing so – some of them built-in utilities in Windows 10 and others third-party solutions.

We strongly recommend you to use Restoro. This is a great software that can check and clean your storage for errors. This system optimizer tool will restore any altered file in your system to protect your hardware.



Use Restoro and avoid any other calculating time error by keeping your storage healthy.

3. Disable your antivirus temporarily

Even though Windows 10 comes with the fairly competitive Windows Defender, the majority of Windows users still places their trust in third-party antimalware solutions. And rightfully so.

However, certain third-party antivirus suits don’t work well with Windows 10. They are, arguably, better than their peers in many regards.

They can slow down the system and affect the performance of the simplest of operations — this includes copying.

Namely, the real-time protection of certain antivirus solutions will try to scan the files while they’re being transferred.

And if you already have issues with the lackluster hardware or system bugs, that’s certainly something you don’t need.

So, we recommend disabling the antivirus for the remainder of the data transfer. Once you copied everything, you can perform a localized scan to check for the virus presence.

4: Use alternatives

There’s a lot of different third-party File Transfer tools which might just work. The majority of those (if not all) are free to use and rather simple to handle.

  • FastCopy – fast multi-thread copying tool, not the best design, though.calculating-the-time-required-to-copy-the-files
  • Copy Handler – fast and well-designed, lacks data verifier.calculating-the-time-required-to-copy-the-files

Finally, if you’re repeatedly unable to go past the Calculating the time required to copy the files error screen, but you can confirm that the storage media is healthy, maybe the Explorer is the problem.

We hope one of the above solutions helped you solve the annoying error. In case you have an alternative solution or questions regarding the enlisted ones, feel free to tell us in the comments section below.
