Database Version 6

[informacione]

I am not able to open my DBLite file.

Getting:

Failed to open database: Invalid database version: 6

Can you do smth on this?

Thank you in advance

The error message (Invalid database version: 6) comes from the exception catch when creating an instance of LiteDatabase. Can you try running this with this DB file to see if it works?

public void OpenDatabase(string filePath)
{
    try
    {
        var liteDatabase = new LiteDatabase(filePath);
    }
    catch (Exception e)
    {
        Console.WriteLine("Failed to open database: " + e.Message);
        throw;
    }
}

Thank you Julian, Maybe you thing that I am some kind of coder :) I don't know where to put this code?

I understand, to run this you would have to have some basic dotnet programming skill. Are you sure this file is from LiteDB version >= 4? How old is this file?

You can also try on other viewers: A GUI viewer tool: https://github.com/falahati/LiteDBViewer LiteDB Manager tool : https://darwich.mx/downloads/

Yes I have found a way to open it with LiteDBViewer4 - this app converts me to name.v3.db from name.db Only after this i can open the file with LiteDbExplorer.

The problem is that I can not turn the file back to its original version after making the changes.

Thank you again

This project relies on and directly uses LiteDB v4 assembly, if core LiteDB v4 is not compatible with older versions this project is not also in a simple way. You can try an old version of the original project (maybe 0.5), see: https://github.com/JosefNemec/LiteDbExplorer/releases

Another option to try would be to create a new build of this project by doing the dowgrade of the LiteDB DLL version (require dotnet skill), but something must break due to version Breaking changes.

Anyway when I have time I will try to test this to see if it works. I will also take advantage to implement the upgrade process as in LiteDbExplorer.

Without pretense of supporting versions prior to 4 this issue will be closed.

In version 0.8.0 the error message on the case was improved and in the future a tool will be added for one way migration from version 3 to 4.

If you have more information and/or questions please comment or open a new one.
