What is a BLF file?

Log file created by the Common Log File System (CLFS), a Microsoft Windows component used for creating transaction logs; contains metadata that is used to manage access to the log data; can be created using the CLFS (API); used with "containers," which are associated files that hold the log data.

More Information

BLF files are commonly seen in the Windows user directory (C:\Users\[user]\). This is because the Windows component that writes user-level registry information to the NTUSER.DAT file in that directory uses CLFS logging. There may also be .REGTRANS-MS log container files in this directory, which store the log data. Another common location for BLF files is the following directory:
C:\Windows\System32\SMI\Store\Machine\

Base log files are system files that are hidden by default in Windows. In general, you should not modify or delete them, since they can contain important user and system-level information, such as user passwords, account settings, and application settings.

NOTE: Because CLFS logs are used with transactions, they can potentially be left in an inconsistent state. This has been known to cause issues with Windows updates where BLF files are left in an inconsistent state. Consult the Windows support documentation to resolve this issue.

What is a BLF file?

Embroidery design file created by MasterWorks, a digitizing program used to create digital embroidery designs; stores shapes, colors, and outlines for the design; used for storing and editing a design before exporting it to a machine-compatible stitch file format.

More Information

BLF files provide greater flexibility when creating designs, since users can work at a higher level with shapes and outlines instead of at the lower machine-specific stitch and thread level. This non-destructive editing process enables the designer to export a stitch file at any time without causing any of the original design elements to be changed.

NOTE: Example export stitch formats include .PES and .DST file.
