MEGA vs TeraCopy

Linux, Windows and Mac.

All files uploaded to Mega are first encrypted on the users side. To access files a decryption key must be supplied. For ease of use, the decryption key can be appended to the URL you share.

50 GB trial for new accounts after registering for a month, then 15 GB. There's also three upgrade plans, starting at 500GB and $110/yr. 15GB may not seem much, but Dropbox only offers 2GB for the free plan. This is better than Google Drive because Google Drive storage is shared with all the Google services you are using.

Just drag and drop files in the browser window, then create a link for sharing. You will need an account to create a link. To streamline the process for new users you can start uploading as soon as you access the website and create an account while it's uploading.

They will never look through your files unless they ask for permission.

It deletes files much much faster than built in Windows file manager.

TeraCopy can automatically check/verify the copied files for errors, by calculating their CRC or other checksum/hash value.

TeraCopy skips badly copied files during the copying process, and then displays them at the end of the transfer "Verify" with checksum/hash, so you can see which files to re-copy. See also, OpenHashTab for Windows and DeadHash for Windows, Linux, Android.
