#12731 closed Bug report (wontfix)

FileZilla trims trailing spaces from directory names when creating directories, but not when downloading files

Reported by: Jon Penn Owned by:

Component version: FileZilla Pro 3.59.0 Operating system type: Windows
Operating system version: 10 (build 19044) x64


I find this issue when connecting via SFTP to MacOS's built-in ssh server, though I expect the issue occurs with all SFTP servers.

To reproduce

  • On the server create a directory ending in a space (ex: "Test ")
  • Add some files to the directory (ex: "1.txt", "2.txt", etc.)
  • Connect to the server via SFTP using FileZilla on Windows
  • Attempt to download the directory


  • FileZilla will create the directory "Test" (notice no space)
  • FileZilla will attempt to download "1.txt" to "Test \1.txt"
  • FileZilla will encounter an error because the folder "Test " does not exist


  • Manually create "Test " NOTE: most Windows utilities will trim spaces from a folder name. I was able to create the directory using WSL 1.0
  • Re-try downloading the folder
  • FileZilla will create the folder "Test", but will download files to the "Test " folder you manually created.
  • You can manually delete the empty folder "Test"

Proposed solution

FileZilla should either

  • Correctly create directories with spaces OR
  • Always trim spaces from folder names

Trailing spaces are not supported on Windows.


Do not end a file or directory name with a space or a period. Although the underlying file system may support such names, the Windows shell and user interface does not.
