If you are looking for file encryption software on Windows, GiliSoft File Lock Pro covers the core workflow: encrypt files and folders, decrypt them when needed, add password-based access control, and use portable encrypted packages for data that needs to travel more safely.
Encrypt files and folders so private data becomes unreadable without the right password or decryption method.
Move between encryption, decryption, locking, and hiding depending on how much protection you need.
Use portable encryption when files must be shared or carried outside the main PC.
What Is File Encryption?
File encryption is the scrambling process that makes files unreadable until the proper decryption method has been employed. The most common use of file encryption software is to protect private files, documents, and other sensitive information from unauthorized access.
File Encryption and Decryption
Encrypting and decrypting files means applying an encryption algorithm to computer files so they cannot be read in normal form. Once decrypted with the correct method, the files return to a readable state for legitimate use.
Portable Encryption Workflows
One useful capability from the original File Lock Pro workflow is portable encryption. The software can package and encrypt a folder into an executable file with AES-based protection, making it easier to move important data across systems without exposing the original files in plain form.
Why This Search Phrase Still Matters
Many users still search directly for file encryption instead of more specialized security terms.
This page preserves that clear search intent while mapping it to the broader protection workflow inside File Lock Pro.
It also creates a clean path to password protection, file locking, and portable encryption pages.
