GuidesWriting files

Copy a file to another location with Bun

This code snippet copies a file to another location on disk.

It uses the fast Bun.write() API to efficiently write data to disk. The first argument is a destination, like an absolute path or BunFile instance. The second argument is the data to write.

const file = Bun.file("/path/to/original.txt");
await Bun.write("/path/to/copy.txt", file);

See Docs > API > File I/O for complete documentation of Bun.write().
