How to open .BSD files on Linux

To open .BSD files on Linux, in a file manager, check the detected type; many distributions map *.bsd to chemical/x-crossfire via shared-mime-info.

Step-by-step instructions

  1. In a file manager, check the detected type; many distributions map *.bsd to chemical/x-crossfire via shared-mime-info.
  2. Try opening it with the chemistry/Crossfire-compatible application you use for chemical data; if none is associated, set an application association via “Open With…”.
  3. If detection is wrong or it still will not open, verify the file source and request an export to a better-supported format.

Alternative methods

  • Open .BSD in a browser-based viewer if desktop apps fail.
  • Try opening .BSD on Linux with a secondary app to rule out app-specific issues.
  • Convert .BSD only with trusted tools when direct opening is not possible.

Common issues

The file opens with the wrong app or shows as an unknown type

.BSD is not universally recognized across operating systems, and the chemical/x-crossfire identification is primarily a desktop MIME-database convention rather than an official, globally registered media type.

  1. Ask the sender what application created the file and whether it is a Beilstein Crossfire/Crossfire-related export.
  2. On Linux, update/rebuild MIME databases if needed and re-associate the file to the correct application via “Open With…”.
  3. Open from within the intended chemistry application using an Import/Open command instead of double-click.

“File is corrupted” or import fails

The file may be incomplete (transfer/download issue) or not actually a Crossfire/Beilstein file despite the .bsd extension.

  1. Re-download or re-copy the file and compare file size/checksum if the sender can provide one.
  2. Verify the format with the sender; request a fresh export from the source system.
  3. If you suspect the extension is misleading, identify it by content on a desktop system before trying other tools.

No software available on mobile to view it

Crossfire/Beilstein .BSD files are specialized chemical data files and typically require desktop chemistry software; mobile platforms often lack compatible viewers/importers.

  1. Transfer the file to a desktop OS where the appropriate chemistry/Crossfire-compatible tool is available.
  2. Ask the sender for an export to a more commonly supported chemistry interchange format used by your toolchain.

Security note

.BSD (chemical/x-crossfire) is a data file, but it may still trigger vulnerabilities in complex file parsers; only open it in trusted, up-to-date chemistry software, especially if it came from an untrusted source.
