Szenario (illustrated by the attached screenshot):

Undeletable.png 
  1.  Using drag & drop (setting: move into TheBrain), I've moved a folder from the file system into TheBrain.
  2. As the folder was empty I chose to forget it.
  3. Then I opened the report area to display the 'Forgotten' thoughts.
  4. Using the menu in the 'Sort' line, I chose to delete all forgotten thoughts.
  5. Then I got this silly GERMAN error message (my translation into English: Source and target paths must have identical root directories. You cannot move across volumes). Source and target were/are on the same volume!

This message is silly, because I chose English for my interface language. So where does this message come from? Why can't I delete an empty folder within TheBrain?

Right now, I'm stuck with these forgotten thoughts that I can't delete.

Reinhard,

Thank you for sharing. I'm attempting to replicate this issue.  Can you confirm that the "functional programming in Python" folder was empty and you moved it into TheBrain.  Then forgot the thought.  Then deleted all forgotten Thoughts from the report - correct?

Thank you,
Matt

Matt,
thanks for your response! Let me try to illustrate this with yet another video clip.
It might help if you read this text in parallel to the video clip and start and stop the clip at the corresponding sentences of the following description.

Szenario:
I have copied this very page to an empty folder using the 'Save as' command of Firefox.
In my Brain, I have created a thought named 'Undelete Demo'.
At this point the video starts.

At the top you see my brain, at the bottom the copied page (two files).
First, I drag & drop both files onto the thought 'Undelete Demo'.
During this process an 'Unexpected Error' happens (second 00:08).
I accept the default in the corresponding dialog box an click on 'Continue'.
The drag & drop process finishes.
Then I open the 'Notes' area of the thought.
Besides 'Notes', the two imported files (one folder + one file) ar shown.
The I open the context menu of the thought 'Undelete Demo' and select 'Forget "Undelete Demo"'.
After that, I close the Notes area and open the Report area with Thoughts 'Forgotten' selected.
There you see my undeletable thoughts together with the newly forgotten 'Undelete Demo'.
Now I try to delete all forgotten thoughts.
A 'refresh' shows, that this didn't work (at 00:50).
Now I choose 'Delete "Undelete Demo"' from the context menu of the forgotten thought.
But this also doesn't work.
I reopen the Notes area of the thought (at 01:05) and try to delete the folder attachment (at 01:09).
This gives a final 'Error while deleting' 'Contraint' (at 01:14).
From then on the thought is undeletable.

This process is reproduceable.
I guess, that the first error ('Unexpected Error' at 00:08) is the decisive factor.
Somehow TheBrain doesn't seem to able to import all of the contents of the folder.
Normally, it's not a problem to move such folders around that have been created by Firefoxes's 'Save as' command.

I hope, this helps a little more.

PS: That's not a Firefox problem. The same happens with Chrome.

Matt,
I cannot confirm that the folder was empty, but probably there was an error while copying the folder into the brain.

Reinhard,

Since we can't replicate this issue in house, would it be possible for you to create a small, test Brain with an undeleteable thought in it?  Send us the .brz and we'll see if we get the same results...

Thank you,
Matt

On Oct. 16th, I already sent a brain to your support team ('Att: Matt Caton, Unforgettable Thoughts')
I just resent it to your support.
And the attached zip file contains a brz file with an undeletable thought.

Hi, Matt,

I've just procuded yet another video clip to demonstrate the whole process from a new brain to an undeletable thought,
Attached are the clip and the brz (both in zip archives).

I'm afraid I may have an easy answer in the case of the first "Undeletable" Brain you've shared.  You cannot delete the HOME thought.  The Undeletable Brain you sent has just one thought, it's the home thought and it cannot be deleted.  If I create a new thought and assign it as the home thought, I can then go back to the "Undeletable" and delete it.

I'll test with your other shared .brz to verify if this is the case for others of if more testing is needed. Just wanted to keep you posted.

Disregard the previous message. I now see that your TypeScript thought was already forgotten. I'm now seeing that the Thought cannot be deleted... this is a good step forward.  I'll keep you posted.

Thank you,
Matt

Reinhard,

We believe running the Data Integrity Scan in the current build of v10 will resolve this issue. I've followed up with you in your support ticket.

Thank you,
Matt
