Knime Local work spaces keep dissappearing

KNIME Analytics Platform

I keep working on a project in my local workspace, make sure to save every time im done and even when i shut out of the app and come back later its still there. but twice now there’s been a bug fix or update and when i come back i have nothing anymore. can’t find my files anywhere

^Also I have a backup folder in my computer with the project name in it, but the project is under a folder and every single thing inside is as well almost like there’s no actual file to open.

Hi @brenttucker, I’ve not heard of anybody having this problem, so I have a few questions which may help somebody work out what’s going on.

  1. What version of KNIME are you using and on what OS ?
  2. Are you saving the project on your local hard drive or a network share?
  3. Are you saving it to a cloud-backup/sync drive such as onedrive?
  4. When you mentioned a bug fix or update, do you mean an update to KNIME, or an update of something (e.g. the OS) external to KNIME?
  5. Are you sure that each time you open KNIME, it is looking at the correct workspace? Is it possible you are choosing a different (empty) workspace and that your project is in a different (still local) workspace?
  6. Do you have any other projects which are affected / unaffected, or is this your only project that is affected in this way?
  7. Would you be able to upload screenshots of what you are seeing in your backup folder, and also in your KNIME workspace, when you look there using your operating system’s file explorer.

Hi @brenttucker , when you performed the upgrade to 5.4, did you use the options within KNIME itself to update, or did you do a fresh download of 5.4?

Thanks for posting the screenshot of your backup folder. The “KNIME_project” folder is the form I would expect to see of an actual KNIME project called “KNIME_project”. KNIME doesn’t have a single openable project file, but instead the workflow will be held as a folder containining individual xml (and other config) files in subfolders for each node within the workflow folder (e.g. KNIME_project).

Where is your current KNIME workspace? Is it this?

c:\users\<username>\knime-workspace

I know you said that there is nothing in it other than the examples, but could you upload a screenshot of that, just to be sure?

You also could try this:

  1. Make sure KNIME is currently closed.
  2. I’ll assume that your workspace is as above. Create a new folder in there called recovered_projects
  3. Manually copy the KNIME_project folder (and all its contents) directly to
    the “recovered_projects” folder you just created

so you’d then have a folder called something like this:

c:\users\<username>\knime-workspace\recovered_projects\KNIME_project

and that folder should have all the subfolders etc that we see in your above screenshot

  1. Open KNIME
  2. You should be able to navigate to the recovered_projects folder and then in that should be the copy of the backup KNIME_project
  3. You can then copy/move/“save as” this project to somewhere else.

btw, the reason for creating the recovered_projects folder was simply to avoid accidentally overwriting and corrupting any existing project in your current workspace called “KNIME_project”.

I did the update after i already had to files disappear, it was a thing that said it was “repairing the app” on my company computer. I am curious though if everything in the workspace becomes folders them how can you upload that to knime to reopen the workflow?
