Summary
Ensuring the security of our data is crucial in today's digital world. Whenever we share sensitive documents or information, encryption is vital to shield it from unauthorized interception. Let's focus on transmitting files via LINE on PC, and explore two robust encryption software options that not only safeguard our data but also underline the significance of protecting our information with diligence.



I. About LINE

LINE is an instant messaging software developed by “LINE Co., Ltd.”, a subsidiary of Naver Group in Japan. It supports Android, iOS, and PC. Users can send messages, watch live broadcasts, make mobile payments, and access news.

LINE now supports online transfer of files other than pictures with the latest version update. However, it is important to note that file transfer on the LINE platform does not include encryption processing, posing a potential security risk for information leakage. To enhance file confidentiality, it is advised that LINE users encrypt their files before utilizing the file transfer function.

II. About the file format

Before introducing how to encrypt files, let’s introduce several common file formats:

1. Exe File

The full name is “executable file”, translated as executable files in Chinese, including “DOS”/“16-bit”/“32-bit” executable files. Encrypting a confidential file into an EXE format allows direct decompression without a password. Additional decryption software is widely used.

2. GFL File

Files in GFL format are special, and specific software is required to decrypt them, for example: use “Renee File Protector” to Encrypt the file into GFL format, and then the recipient needs to use “Renee File Protector” or other specific decryption software to unlock the file.

3. Zip File

Zip format is a compressed file format that allows for encryption and reduction of memory space. However, its public nature has led to the abundance of cracking software for this format.for this format abounds.
After understanding these three common encrypted file formats, the following two safe and efficient encryption software will be introduced to you to help you encrypt files.

Files with Renee File Protector

Renee File Protector is a professional file protection software that enhances file security. It effectively locks and hides files on both local computers and external hard drives, while also restricting file operations.
