The sw file extension is mainly related to some older 16-bit RAW audio format. Most likely no longer actively used.
The sw file stores some kind of RAW PCM audio data.
Awave Studio still supports this file format and can open it.

Free Pascal is an open-source compiler suite, and an SW file provides assembler source for projects built with it. The file is normally plain text containing processor-specific assembly instructions, symbols and directives.
Free Pascal can use assembler source as part of a program's build process. The assembler code is combined with other Free Pascal source and compiled into the program or object code required by the target platform.
This file type is associated with the Windows and OS/2 versions of Free Pascal. Because it contains platform- and processor-dependent source code, it is intended for use within the corresponding Free Pascal toolchain rather than for general interchange.
An SW file can be opened for inspection or editing in a plain-text editor. To use it as source code, open the relevant project in Free Pascal on Microsoft Windows and include the file in the project's build configuration as required.
The source may not be meaningful when opened as a document because its instructions depend on the target processor and the surrounding Free Pascal project.
There is no general-purpose conversion for an SW file. It is source code, so its usual use is to assemble or compile it with the appropriate Free Pascal toolchain rather than convert it to another file format.
Moving the source to another assembler or target requires manual changes to the assembly syntax and platform-specific code. Compilation produces program or object output, not a converted SW file.

Swiss-Prot is a manually curated biological database of protein sequences. It was created in 1986 by Amos Bairoch during his PhD and was developed by the Swiss Institute of Bioinformatics and the European Bioinformatics Institute, now EMBL-EBI. Swiss-Prot is maintained as the reviewed section of the UniProt Knowledgebase by the UniProt consortium.
The database aims to provide reliable protein sequences with detailed annotation, including protein function, domain structure, post-translational modifications and variants. It also aims to minimise redundancy and provide extensive integration with other biological databases.
A .sw file contains the database's flat-file records rather than a conventional relational database. The MIME type for this format is chemical/x-swissprot.
A .sw file is a plain-text database file. It can be viewed with a text editor on Windows, macOS or Linux, although the structured records are easier to use with bioinformatics software that supports Swiss-Prot or UniProt flat files.
For searching and annotation rather than simple viewing, use the current UniProt database services or a compatible sequence-analysis tool.
A .sw file does not normally require conversion for archival or text-based use. Individual protein records can be exported from UniProt in formats such as FASTA, XML or tab-separated text, depending on the intended use.
Because annotations and sequences can be lost when changing formats, conversion should be performed with a tool that understands Swiss-Prot or UniProt records.
