When you are moving the standard installation of AutoCAD 2023 or large project files, choosing the right platform is critical for speed and security.

Encrypt first, then transfer. Use Internxt or Proton. And always split those massive AutoCAD assemblies. Bottom Line: Encrypt first, then transfer
When you need to send legitimate, large project files securely, the following services offer robust free tiers: Bottom Line: Encrypt first
For projects exceeding 1GB, the user must pivot to a more aggressive, though still free, strategy: . Services like Google Drive or MEGA (which offers 20GB free) provide robust transport encryption (TLS 1.3), but server-side access is technically possible. To achieve true "secure transfer," one must encrypt the AutoCAD file before upload. The free, open-source utility 7-Zip (or its command-line equivalent) is the ideal partner. By right-clicking a collection of .dwg files and selecting 7-Zip > Add to archive , the user can choose AES-256 encryption—the same standard used by the U.S. government for classified documents. Creating a self-extracting archive ( .exe or .7z ) with a 32-character password ensures that even if the free cloud host suffers a breach, the AutoCAD data remains mathematically indecipherable. The receiving party only needs the same free password to decrypt. This two-step method (compress, encrypt, upload) turns any free cloud provider into a secure vault.
