File "missing" is mostly due to problems such as unattention of the saving path, name memory deviation, file hiding or cloud synchronization. Efficient management suggestions: Classify by project, time, and type, make good use of quick access, clean and archive regularly, and standardize naming.

There is no native folder password function, because the operating system focuses on account permissions and full disk encryption. Windows and macOS ensure security through mechanisms such as BitLocker and FileVault to avoid vulnerabilities caused by simple passwords. A common alternative is to encrypt folders with compression software such as 7-Zip, select AES-256 and check "Encrypted File Name", and delete the original file after generation. For higher security requirements, you can choose BitLocker encryption VHD, create encrypted .dmg images on macOS, or create encrypted containers using VeraCrypt. EFS can bind user-encrypted files, but it is poorly portable. It is recommended to compress and encryption in daily life, and select system-level or professional tools for sensitive data.
