Write access forbidden

Tobias Dietrich

Is it possible in notepad++ to set an option that I can´t open the same file with write access.
In microsoft word if I want to open the same file twice I will get an message that the file is already opened.
We have the problem that several persons edit one file with notepad++. I will get an message if an other person has opened the file already.

Please can you help me?

at this time are you seeking a plugin or script who notify if file has already opened in npp or another editor ?

Tobias Dietrich

Yes an plugin or if there is any setting to change this.

rinku singh

document list panel can show you file has set as read only

setting > preference > general > document list panel

Tobias Dietrich

With document list panel I can´t see that the file is already opened by an other user.

rinku singh

yes i have c# code for write a plugin for notify if file in use (file is busy) but not sure it works file who in use by other user

protected virtual bool IsFileLocked(FileInfo file)
{
    FileStream stream = null;

    try
    {
        stream = file.Open(FileMode.Open, FileAccess.Read, FileShare.None);
    }
    catch (IOException)
    {
        //the file is unavailable because it is:
        //still being written to
        //or being processed by another thread
        //or does not exist (has already been processed)
        return true;
    }
    finally
    {
        if (stream != null)
            stream.Close();
    }

    //file is not locked
    return false;
}

I don´t know, how I import this code as plugin.

rinku singh

file is just not busy by npp

Tobias Dietrich

I don´t know what I should do with this c# code.

@Tobias-Dietrich ,

Currently you cannot know that another person has already opened the file.
It is because the file is kept open for a very short time (only when reading it or writing it) and then it is immediately closed.

Ok many thanks for your answer. I know that other editors can lock this file during it is in use.
Is that option planned for development?

I don’t know but I don’t think so.
