Help ! Mysterious large Group (5681 items, 1.9 GB) appeared in Global Inbox

I discovered a Group in my Global Inbox. I don’t know when it appeared. One thing is certain: I never deliberately created it.

The Group name is Conversion Engine EML RTF in the Global Inbox database.
Description of the group: it contains only one subgroup called applications and many many subgroups of Engine EML RTF/Applications which all seem to contain a wide variety of file types: “package”, txt, jar, htm, etc.
Items: 5681 in total, occupies 1.9 GB space. There are no indexed items, no duplicates and no replicants. File types: “package”, txt, jar, htm, etc.

I created a smart rule (see below) in the past to automatically convert my imported email messages (eml) to rtf so I could annotated them. Ironically, I had even checked with forum members that my smart rule was OK.


  • why would the group have been created ? could it be related to the smart rule ?
  • I will delete the smart rule. Can I safely delete the group ? How could I be 1,000% sure that it contains no index items. Below is the smart group I created to make sure there were no smart items. I really don’t want to mess up my Mac applications, so I would like to double check.

thanks in advance for your time and help

Neither DEVONthink nor smart rules import anything on their own, the most likely reason according to the screenshot seems to be drag & drop of a subfolder of /Applications onto DEVONthink’s Finder icon (or into DEVONthink’s Inbox folder or to a folder having attached folder actions).

Does smart group return any indexed items? Otherwise there are none.

Thank you Christian.
I had another look:

  • The group in question contains a series of subgroups which correspond exactly to all the subfolders of my applications folder which is very strange. I don’t think it could be a be a drag and drop error.
  • it remains strange that the name of the group that suddenly appeared
    — corresponds exactly to the name of the smart rule and
    — also that the name is Conversion Engine EML RTF which is very unusual. In other words it is unlikely that the resemblance with the smart rule name is simply a coincidence.

please note that I never consciously drag and drop into DevonThink

I wonder if it could be a glitch if I added a Finder or Pathfinder DevonThink add-on. Is there such a thing, so I can remove it ? thank you

The only add-on for the Finder is the sidebar alias for the Global Inbox. There is none for PathFinder.

I can’t find the add-on in Finder, and I don’t know which “folder” in the sidebar could be the DevonThink one (because I want to remove it). Where could I find information on it the DevonThink Finder add-on, including removing it ?.
thank you very much

If I drag and drop into the sidebar icon, are the files in DevonThink imported or indexed ? thanks

Imported. That’s always the default behavior.

OK, I found the add-on. thank you

You’re welcome :slight_smile:

Do you think you may have accidentally dragged and dropped the /Applications folder on the Inbox alias? (PS: Stranger things have happened… and some intentionally! :open_mouth: )

Yes, and I would add that I am error prone.
My question may be academic, but I am still puzzled by the question I asked @cgrunenberg here

That is indeed highly unusual. No precedent for it, I’m afraid.
