I use a folder/file Syncing program called FreeFileSync (FFS). It's not intended to ensure the copy you have is exactly the same as the original author had before you acquired it. All Teracopy was ever intended to do was copy a file that you already have to another location of yours, then verify that the copy made is exactly the same as the file you already had. If you like this app then it can be installed with:
I then checked the repos and it looks like ultracopier is in the Mint repos. I checked the website and it listed Ultracopier. It's just a good way of assuring yourself about the integrity of the newly copied or transferred files.Īh, ok TeraCopy is checking for corruption during file transfer. As for as I know, TeraCopy creates the checksums on-the-fly, then copies the files and compares their checksums to the original ones. I am not thinking about downloads, but local file transfers on the computer. There is a big difference between verifying file integrity from the author's hands and verifying that a file isn't a corrupted download. If TeraCopy is producing both checksums (before copy and after copy) then TeraCopy could be producing a checksum of a hacked file and you won't know the file was a hacked copy of the author's file. Is that what TeraCopy does? Or does TeraCopy simply create a checksum before copy and then compare that to another checksum TeraCopy produced from the downloaded file? The difference is that someone can replace the author's file on the server with a hacked copy and the user won't know the difference without the author's checksum. Now, in order for TeraCopy to do what I'm assuming it does, it needs the checksum that the author produced and then match that checksum to the file after you have received it. If the checksum the author has produced does not match the checksum that you have after receiving the file, then the integrity of said file cannot be confirmed.
In order to verify that the file you received is an exact copy of the file as it was when it left the author's hands, both you and the author need a matching checksum. I'm not sure TeraCopy did what you think it did.
Is there any way to make the built-in file transfer utility in Nemo do this? Or would you need a completely different file manager? This feature is something I miss on Linux. It does this by CRC checksumming them on the fly. For Windows, there is this nifty program called TeraCopy, which automatically verifies the integrity of all files that are copied/transferred.
