About EFS files

EFS (Encrypting File System) is a file encryption service provided by Microsoft Windows operating systems. It allows users to encrypt individual files and folders, as well as entire volumes, to protect them from unauthorized access. EFS files are generally identified by the .EFS extension.

EFS files can be converted using a variety of software, such as various tools, DiskInternals EFS Recovery, and Stellar EFS Data Recovery. These tools can be used to convert EFS files to other file types, such as .ZIP, .RAR, .TAR, .7Z, .PDF, .JPEG, .PNG, .GIF, .TXT, .DOC, .DOCX, and .XLSX.

When converting EFS files, it is important to consider the security of the files, as the encryption may be lost during the conversion process. Additionally, due to the complexity of the encryption, conversion of EFS files can be difficult and time-consuming. Furthermore, the encryption used by EFS is not as strong as other encryption methods, making the files vulnerable to attack.

For these reasons, it is recommended to use a free and easy online website, such as Convert.Guru, to convert EFS files. Convert.Guru offers a secure and simple way to convert EFS files, without the need for any additional software or tools.


The EFS Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best EFS converter by continuously improving quality, usability, and reliability.
