Extract text from backup files (BK)
To convert BK backups to another format, you need Samsung Smart Switch or other Backup software.
To convert other file formats to the "Application Archive File" file type, you need software like Samsung Smart Switch or a similar tool.
A .bk file is primarily used as a generic application backup, typically generated by various software platforms to save user configurations, mobile device states, or databases. The most prevalent uses include mobile device backups via Samsung Smart Switch, SQLite database backups for browsers like Google Chrome, and Adobe FrameMaker book files.
Because .bk is an arbitrary extension rather than a strict, standardized format, its internal architecture varies drastically. Many .bk files are essentially renamed ZIP archives or plain text JSON and SQL files. The main disadvantage is that the .bk extension obscures the true MIME type. This causes operating systems to throw errors when users try to open the file directly. Proprietary formats, like those exported by Machenike keyboard software or encrypted Samsung backups, are locked to their specific ecosystems and require the original app to function.
Users usually need to convert or extract .bk files to migrate contact lists, restore databases, or recover lost system settings. The ideal target formats depend heavily on the file's internal signature. Renaming the file to ZIP often allows for quick extraction, while text-based payloads can be parsed as JSON or SQL. Forcing a format shift on an encrypted backup will corrupt the data.
This file format is notoriously difficult to open or convert because standard web tools rely entirely on the extension rather than inspecting the actual binary header. Our platform analyzes the internal byte structure of the .bk file.
Convert.Guru analyzes your BK file, detects the exact format, and lets you read the text inside.
Users also converted BK09, SNMM, SPBM, SDOC, BAK, BK_BACKUP, BK!, ZIP, SCW, WBK, BK2, ENC and LIST files.
If you want to convert BK file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Samsung Smart Switch or similar software from the "Application Data Backup" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to BK, try Samsung Smart Switch or another comparable tool in the "Application Data Backup" category.
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 BK converter.
