What is an A1 file?

An A1 file is an archive created by the Free Pascal compiler on the go321v1 platform. It likely contains compiled Pascal source code. A1 files can be automatically deleted using delp, a Free Pascal file deletion tool.

More Information

When compiling .PAS and other Pascal-related files, Free Pascal creates many non-executable files. These files are used during the compilation process but are not needed afterward.

A1 files are extraneous archives created during the Free Pascal compilation process. Free Pascal creates A1 files when used on the go321v1 platform. On other platforms, Free Pascal creates .a, .aw, and .ao files, which are the same as A1 files.

How to open an A1 file

A1 files are not meant to be opened. If you have Free Pascal installed, you can use the delp file deletion tool to automatically delete A1 files and other extraneous Free Pascal files.
