Encryption from the Context Menu. The feature integrates an encryption option directly into the menu that appears when you right-click any file or folder in Windows Explorer. This integration eliminates the need to open the main application for basic operations, streamlining the data protection workflow.
AES-256 Algorithm. It employs the Advanced Encryption Standard algorithm with a 256-bit key. This encryption standard is the same one used by government agencies and military organizations for protecting classified information, guaranteeing a very high level of security against unauthorized access.
Integrated Password Generator. Includes a tool that generates complex, random character sequences. These passwords, combining letters, numbers, and symbols, possess high entropy, which significantly increases resistance to brute-force and dictionary attacks.
Entire Folder Encryption. The functionality allows you to select a complete directory for processing. The software recursively encrypts all files contained within the selected folder, maintaining the internal structure, which is suitable for large projects or private data collections.
Decryption via Double-Click. Files encrypted with the program have a specific extension and association. Double-clicking on one of these files automatically initiates the decryption process, prompting for the correct password to restore the original content.
Drag-and-Drop Method. Offers support for dragging and dropping items directly into the main application window. Users can select multiple files and folders from different locations and drop them onto the interface to initiate bulk encryption or decryption.
Cross-Platform Protection. Encrypted files generate a protected data container. This container can be transferred and stored on any system or device. Access to the content is only possible with the correct password, regardless of the platform where the file resides.
Secure Deletion of Originals. During the encryption process, the software can delete the original unencrypted files. This deletion is performed using methods that overwrite the data, preventing subsequent recovery through specialized software, complementing the security of the encryption.
Minimalist User Interface. The main application window presents basic controls and a clear workspace. This design focuses on the essential actions of encryption and decryption, avoiding complex menus and reducing the learning curve for new functions.
Support for Multiple Formats. The encryption process is independent of the file type. The application can process text documents, spreadsheets, images, executable files, databases, and any other format, as it operates at the byte level, encapsulating the entire file.
Visible Operation Progress. During the encryption or decryption of large volumes of data, a progress bar and numerical counters display the current status of the operation. This feedback allows the user to estimate the remaining time and confirm that the process is actively running.
Password Management in Memory. The password entered by the user for an operation is kept temporarily in the system's RAM only for the duration of the encryption or decryption process. It is not stored on the hard drive or sent to external servers.

The development of Abelssoft FileCryptor is carried out by Abelssoft GmbH, a German software company founded by Christian Abels. The company started its operations in the year 2000. The first public version of FileCryptor was released in the year 2025, as a modern tool within its catalog of Windows utilities focused on security and privacy. The application is written in the C++ programming language, leveraging robust cryptography libraries and modern Windows APIs to implement the AES algorithm and system integration.
