LR Classic Preview Cache Error - cannot delete db-journal file

My PC Specs - Windows 11, Lightroom Classic V13, RAW files on External HDD. 

I received this error today morning - Lightroom encountered an error while reading its preview cache and needs to stop. 

As per earlier suggestions - I have tried to delete the Lightroom Catalog-v13 Previews.lrdata folder - however, there are two files which are not being deleted - previews.db-journal &  root-pixels.db-journal - with the error stating Adminstrator permission is required. The Security settings of this file already has ALL permissions (including Delete) to Everyone/Admin.

I have deleted all the remaining files in the Previews folder.    

Any idea how to resolve this problem ?

    That could maybe help.

    First, please try resetting the preferences: https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html

    This helps with all sorts of issues, and they are not being reset when uninstalling and reinstalling.


    Ok - so i have now uninstalled the App and re-installed the latest version V13.1. I also shifted the Lightroom Folder from External HDD to C Drive. (Maybe that was the problem - Lightroom Catalogs on the External HDD ??)

    I can now open the LrC successfully. 

    Thank you so much for your help and patience in guiding me through this process.

    Just to make sure: Did you stop LrC before trying to delete? Eventually, even restart the PC before trying to delete?

    Yes - LrC was not running while trying to delete. I even restarted the PC - same issue. 

    However, the first time the error occured, i closed LrC and restarted it, instead of waiting for LrC to stop by itself. Maybe thats the reason for the journal files to remain in the folder ?? But the question still remains - what next ?

    The journal files are usually only there while LrC is running and vanish as LrC is closed.

    While LrC is not running, check the file properties for a write-protection you can clear.

    If that is not the case, I'd try with Windows started in safe mode.

    And next, install MS Powertoys and use File Locksmith to see "who" is blocking it.
