java - file.createNewFile() IOException "No such file or directory" [closed]

Question

While coding Java had this problem: file.createNewFile() throws IOException "No such file or directory". Checked out other answers but nothing seems to be helpful. Any ideas?..

Answer 1

It's likely that you're trying to create the file in a directory that does not exist.

Use mkdirs() to create any missing parent directories first.

File file = new File("foo/bar.txt")
file.getParentFile().mkdirs();
file.createNewFile();

Answer 2

I think you are trying to create a new file in a directory that does not exist. The whole path needs to exist, only the file can be non-existent.

Answer 3

Oh, I got it. It appeared to be more Windows problem than Java. Actually, even with UAC disabled random app still have no rights to write something on C: (or whatever it is on your system) on Win8. Never got this problem using Win7 though. Using "Run as Administrator" on IDE does not help as it doesn't give such rights to Java compiler. So, I just moved my projects folder to other disk. Also, you can change access rights, but it was easier for me. And yes, nobody mentioned about a chance of this happening in other questions, so I hope it'll be helpful to anyone.

Answer 4

You need to create the Folder first. createNewFile cannot create them:

File folderFile = new File("c:\\this\\folder\\has\\subfolders");
folderFile.mkdirs();

File myFile = new File(folderFile,"myfile.txt");
myFile.createNewFile();
