About CBM files

A .cbm file is a highly fragmented format, most frequently acting as a Backup Cache Bitmap created by Carbon Copy Cloner or a compiled machine learning model from CatBoost.

In backup scenarios, Carbon Copy Cloner uses .cbm files to track block-level changes on macOS drives, speeding up incremental backups. The primary disadvantage of this format is its proprietary, internal nature. It contains raw binary cache data that cannot be read by standard text editors or web browsers. Opening it manually will only display garbled text.

Alternatively, data scientists use .cbm for gradient boosting on decision trees via the Yandex CatBoost library. By default, CatBoost saves models in this proprietary binary format. This creates a hard vendor lock-in, limiting interoperability because deploying the file requires the specific CatBoost runtime environment installed on the host machine. You might also encounter .cbm as a game cheat database file used by CheatBook, or even an ancient Commodore 64 BASIC program.

Conversion Recommendations:
Converting a Carbon Copy Cloner cache file is generally not recommended, as it only holds temporary backup state data. However, for machine learning models, converting your .cbm file is highly practical. For web and cross-platform deployment, convert CatBoost models to JSON, .ONNX, or CPP formats. For cheat databases, extract the content to standard TXT or CSV files to make the data universally readable. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
