About BOOT files
The .boot file extension serves multiple distinct purposes, but it is most notoriously known as an extension appended by ransomware families like Phobos, Dharma/CrySiS, and STOP/Djvu. When these malicious programs infect a system, they encrypt standard files - such as JPG, ZIP, and PDF - and rename them with the .boot extension. Beyond ransomware, the format is also used by Microsoft for compressed installation setups, by Qihoo 360 Antivirus to isolate quarantined EXE executables, and by MediaTek for plain text Android system boot process logs. If your file is a victim of ransomware, the original data is locked behind strong encryption. Standard online converters cannot process these files because the internal file structure is completely scrambled. You cannot simply rename a .boot file back to JPG or PDF and expect your operating system or web browser to open it. Recovering the original formats requires specific decryption tools provided by cybersecurity researchers, not standard format conversion. This file format is exceptionally difficult to open or convert because it is often heavily encrypted or utilizes proprietary archive compression. Standard web converters fail because they lack the decryption keys or the specific extraction logic required for these payloads. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your BOOT file, detects the exact format, and lets you read the text inside.
If you want to convert BOOT file to GPT, INI, CFG, CONF, CONFIG, JSON, XML, YAML, YML, TOML, ENV or PROPERTIES, you can use Emsisoft Decryptor or similar software from the "Ransomware Encrypted File" category. In the File menu, look for Save As… or Export….
To convert ZSHRC, CONF, RCFILE, GITCONFIG, RC, PLIST, BASHRC, CONFIG, PROFILE, INI, PREFS or CFG files to BOOT, try Emsisoft Decryptor or another comparable tool in the "Ransomware Encrypted File" category.
The BOOT Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BOOT converter.
