Cyberduck Mountain Duck CLI

#8644 closed enhancement (wontfix)

Removed placeholder when the directory is no longer empty

Since S3 has no notion of directories, Cyberduck seems to be creating an empty file when you use the "new folder" command. Using the AWS-CLI (can install with homebrew, run "aws configure" after you install), I've verified that there is indeed a zero-byte file that seems to have a space character as its name. This is fine/needed when the directory is empty but once the directory has been populated then this "empty" file should be removed automatically. An alternative is to allow the user to see/delete this file since the user can do neither with Cyberduck at the moment.

Empty file that Cyberduck creates when creating new folders:

~ ❯❯❯ aws s3 ls s3://foo/bar
2015-03-05 17:02:01          0
2015-03-05 17:05:11          0

Should be easily reproduced by the following steps:

  1. Create an new folder in S3
  2. Place a file in that folder that you just created
  3. Use some other means of displaying that directory (Cyberduck won't show it as far as I can tell)
  4. Note the empty placeholder file that was created along with the file you place in that new directory

The placeholder is a key with the name of the directory and a application/x-directory content type set.

  • Resolution set to wontfix
  • Status changed from new to closed

The placeholder is deleted when removing the directory. If the placeholder would be automatically removed when uploading a file into it it would lead to unexpected results when removing all files from the path with the directory disappearing as well.
