How Can I Copy Encrypted Files to Another Computer Safely?
Asked by

I have several PCs on my home network, and I've encountered an issue when I try to copy an encrypted file from one PC to another that doesn't have encryption enabled. Every time I attempt this, Windows prompts me asking if I want to copy the file in an unencrypted format. Unfortunately, there's no option that allows me to keep it encrypted during the transfer. Is there a way I can change this behavior and ensure the file remains encrypted, even though the other computer isn't set up for encryption?

You’re correct; encryption is linked to hardware keys, and you have to decrypt the file before transferring it. Directly copying encrypted files to a non-encrypted environment typically leads to decryption during transfer.

Unfortunately, you can't copy the file while keeping it encrypted if the destination computer doesn’t support it. The encryption is managed by your operating system, and it will default to transferring the file unencrypted. If you need to keep it secure during transfer, consider using an encrypted file transfer method like HTTPS.

If you’re dealing with NTFS encryption, it’s tied to the account on the original PC. Unless both computers are on the same domain and the accounts are compatible with NTFS, the encryption won’t carry over. Therefore, if your computers aren’t domain-linked, the file will just lose its encryption during the copy. To keep it secure in transit, consider copying it to a USB drive with encryption software first.
