How to copy a file to a directory in Java 7

Question

I\'m trying to copy a number of files to an output directory in Java 7 using Path and Files. This doesn\'t work:

Files.copy(Paths.get(\"/my/file.txt\"), Paths.ge         


        

Answer 1

From docs Java 7:

copy(Path source, Path target, CopyOption... options)

Copy a file to a target file.

So you must specify destination file.

I have a large number of files

You can get file name by splitting source path and append to destination folder.

Answer 2

The easiest way:

Path file = /* path to source file */
Path to = /* path to destination directory */
Files.copy(file, to.resolve(file.getFileName()));

Answer 3

The command appears to be attempting to replace the directory itself. Try specifying the filename in the target directory

Files.copy(Paths.get("/my/file.txt"), Paths.get("/my/output/directory/file.txt"));
