How to open .BSD files on Windows
To open .BSD files on Windows, confirm the file’s origin: ask the sender which application generated the .BSD file and whether it is a Crossfire/Beilstein export.
Step-by-step instructions
- Confirm the file’s origin: ask the sender which application generated the .BSD file and whether it is a Crossfire/Beilstein export.
- If you have the originating chemistry/Crossfire-compatible software installed, use its File → Open (or Import) rather than relying on double-click.
- If you do not have compatible software, request the sender to export/convert it to a format your tools support (do not rename the extension as a “conversion”).
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.
- Ask the sender what application created the file and whether it is a Beilstein Crossfire/Crossfire-related export.
- On Linux, update/rebuild MIME databases if needed and re-associate the file to the correct application via “Open With…”.
- 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.
- Re-download or re-copy the file and compare file size/checksum if the sender can provide one.
- Verify the format with the sender; request a fresh export from the source system.
- 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.
- Transfer the file to a desktop OS where the appropriate chemistry/Crossfire-compatible tool is available.
- 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.
