Now, it is important to not mess up the ordering (some ciphers will tolerate this, but some will not) DECf(C) != B, and DECv(DECf(C)) != A (probably). "ENCv" and "DECv" are the volume-wide (VeraCrypt) encrypt and decrypt functions, using VeraCrypt's key for that volume.) "ENCf" and "DECf" are the per-file encrypt and decrypt functions, using the key you supply. ("A", "B", and "C" are placeholder variables for the actual data, not literal values. Encrypted file is read off the disk and into the per-file decryption utility: DECf(DECv(C)) = DECf(B) = A.

Encrypted file is download from a cloud service to an encrypted volume: ENCv(download(B)) = C.

Encrypted file is uploaded to a cloud service: upload(B).

Encrypted file is read off of the encrypted file system (for example, to upload): DECv(C) = B.

Encrypted file gets stored on an encrypted file system: ENCv(B) = C.

File gets encrypted using per-file encryption utility: ENCf(A) = B.

The cipher neither knows nor cares whether the input data is already encrypted there's no special flag saying "this data is encrypted already!" that might get somehow confused. Encryption doesn't "distort" anything it's a reversible mathematical transformation of the input data.

There is absolutely nothing wrong with encrypting files on a volume (hard disk) that is also encrypted.
