Folders with spaces at the end of the name can not be accessed through the Windows Explorer

[HarrySTrueman]

Steps to reproduce

1. Open a browser and log in to owncloud
2. Create a new folder with name "test "
3. Open the folder and upload one file
4. On Windows open the Windows Explorer (Win+E) and open the WebDav URL for your owncloud instance
5. Click on the new foldername ("test ")

Expected behaviour

The uploaded file should be listed inside the Windows Explorer.

Actual behaviour

An empty folder is shown. If you remove the space at the end of the foldername, then the file will be shown in the Windows Explorer.

Browser log

[michaelstingl]

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. However, it is acceptable to specify a period as the first character of a name. For example, ".temp".

(found in MSDN: Naming Files, Paths, and Namespaces)

[HarrySTrueman]

This could be prevented by the owncloud WebFrontend. At the moment such filenames are allowed.

[PVince81]

I'm ok with preventing this in the frontend

[cdamken]

Problem still exist:

Error Message: Filename ends with a space.

OC 10.0.7 in docker on ubuntu.

Desktop Client 2.4.1
