Description sgunfio 2011-05-27 10:45:04 UTC 
Hi,
i've a project stored on a samba server,
if i rename a directory in file system then refresh, the system is unanble to detect the changement, also if i've two subdirectories  with the same name, but differetne case, I get  just one (e.g. Pages and pages)

Thank you

Are you running on a window machine? Your samba server is using some Unix/case sensitive filesystem? If so, then I can imagine the mess...

Win7 on an ubuntu box via samba.
It's like netbeans is performing an no-case comparison:
if is already in the tree don't add / update the information

To rephrase: you are running Ubuntu Linux. Inside of VirtualBox you have running Win7 and you are accessing the filesystem of Ubuntu Linux via samba.

I can probably create some system property that would define whether files should be case sensitive or not and you could use it to override the defaults.

Is there a native API to query the case sensitivity of FS?

we do it from Java like:
    static {
        boolean caseSenstive;
        try {
            File tmpFile = File.createTempFile("CaseSensitiveFile", ".check"); // NOI18N
            String absPath = tmpFile.getAbsolutePath();
            absPath = absPath.toUpperCase();
            caseSenstive = !new File(absPath).exists();
            tmpFile.delete();
        } catch (IOException ex) {
            caseSenstive = Utilities.isUnix() && !Utilities.isMac();
        }
        TRUE_CASE_SENSITIVE_SYSTEM = caseSenstive;
    }

    public static boolean isSystemCaseSensitive() {
        return TRUE_CASE_SENSITIVE_SYSTEM;
    }

of course you can do the same on any mounted disk without creating temp file,  i.e. get existing file from list of existing files and check if Upper/Lower search returns the same java.io.File

Finally I managed to do something with this issue: ergonomics#be300d5b00bc. Let me know if it addresses your problem a bit.
