Encrypted files have 99% sure have rewritten the original files. Copying the encrypted files will keep them encrypted and that's all.
Your one and only hope to "restore" files is to just unplug the computer right away as soon as they're encrypted, don't even use it. Take the disk out, plug it into another computer (as a secondary drive, DO NOT boot from it) and then try recovering there.
More you use the drive higher the chance of you overwriting the old version but there's likely no old version.
When a file is modified it will likely stay in the same spot:

After it changed it remained in the same inode, didn't move, overwritten, stuff underneath permanently lost, NTFS probably works the same way.
