Bernd Eckenfels commented on VFS-661:
-------------------------------------
It hink it is a good idea to add FileObject#resolveCanonical() returning the
canonical FileName. For local files this would map to File#getCanonicalPath()
However I am not sure if the Cifs API does Support that anyway.
But for your usecase you could either use a case insensitive comparator or
store the URL in lowercase.
FileName resolveCanonical() instead of getCanonicalFile to make it clear it’s a
slow IO intensive method (not the missleading getter from java.io)
> Ability to get "real"/"native"/"physical" file name

> Key: VFS-661
> URL: https://issues.apache.org/jira/browse/VFS-661
> Project: Commons VFS
> Issue Type: New Feature
> Affects Versions: 2.2
> Reporter: Boris Petrov
> Priority: Major
>
> On case-insensitive file systems (local FS on Windows; Samba; etc) resolving
> a file ignores the case that is used. For example, if there is a folder like:
> *smb://localhost/share/folder* and is resolved with
> *smb://localhost/share/FOLDER* it would work and return the same folder.
> However, there is no method in the *FileObject* interface that allows us to
> get the "real"/"physical" name of the folder - i.e. *folder*. All of the
> methods would return *FOLDER* in this case.
> We have a major usecase where we need that. The only solution I can think of
> is getting the parent folder, going through its children and thus finding the
> correct case but the performance of that would be horrible.
