Extract text from BLG files
To convert your BLG file to another format, you need Performance Monitor or other System software.
To convert other file formats to the "Performance Log" file type, you need software like Performance Monitor or a similar tool.
The .BLG extension primarily refers to the Windows Performance Monitor Log, a proprietary binary format used by Microsoft Windows to record system metrics like CPU usage, memory allocation, and disk activity over time. While efficient for recording data without bogging down the system, the raw binary nature of these files makes them inaccessible to standard analysis tools like Microsoft Excel or database importers. Users typically need to parse these logs to troubleshoot server hangs or memory leaks, but are forced to use the clunky relog.exe command-line utility or the legacy Performance Monitor interface (perfmon.exe) just to extract readable data. For practical analysis, the best workflow is converting .BLG to CSV (Comma Separated Values) or TSV.
Less frequently, a .BLG file is a BibTeX Log File generated during LaTeX document compilation. These are plain text files containing error messages and processing statistics for bibliography citations. They don't contain the actual references (found in BIB files) and are typically only useful for debugging compilation errors. You can open these directly as TXT files.
Convert.Guru analyzes your BLG file, detects the exact format, and lets you read the text inside.
Users also converted GLB, X_T, DBG, MP4, EXE and CSV files.
If you want to convert BLG file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Performance Monitor or similar software from the "System Performance Logging" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to BLG, try Performance Monitor or another comparable tool in the "System Performance Logging" 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 BLG converter.
