If no free decrypter exists, the only safe way to get your files back is to completely wipe your hard drive and restore your files from a backup made before the infection occurred. To help me give you the exact steps you need: Where did you find this _D.rar file? Are your other personal files still opening normally ?

Creators use tools like WinRAR to break a large file into segments labeled .part1.rar , .part2.rar , or custom alphabetical indicators like _A.rar , _B.rar , _C.rar , and _D.rar .

Because files ending in .rar simply represent a standard compressed archive, the exact meaning of a file named _D.rar depends heavily on where you found it and how your computer is behaving. 📁 Scenario 1: A Split Multi-Volume Archive

To extract these files, you must have all parts saved in the exact same folder. Right-click the very first file in the sequence (usually part 1 or _A.rar ) using WinRAR or 7-Zip and select "Extract Here". The software will automatically pull data from _D.rar to complete the file. ⚠️ Scenario 2: Ransomware Infection

Do not pay the ransom. Cybercriminals frequently take the money and disappear without providing the decryption key. 🛑 What to do if it is Ransomware

If you downloaded a large program, game, or database, the creator may have split the massive file into smaller, more manageable parts.
