func Copy ¶

func Copy(destFileName string, srcFileSys fs.FS, srcFileName string) (err error)

Copy copies a file or a directory from a source FS to disk. In case of a directory, all nested subdirectories are recursively copied as well. If a file already exists at the destination, it is overwritten.

If a source file name ends with an underscore, one underscore is trimmed before copying. The corresponding destination file name will not include that underscore.

func Exists ¶

func Exists(fileName string) (exists bool, err error)

Exists indicates if the named file or directory exists on disk. The file name is resolved relative to the current OS working directory.

func Mkdir ¶

func Mkdir(dirPath string) (created bool, err error)

Mkdir creates a directory, if it doesn't exist. The directory path is resolved relative to the current OS working directory.
