Impossible to move a file to the destination folder because there is not enough available space
Hello, looking for some help. I have been transferring my old jpeg pictures from my iMac Picture folder into Lightroom. I was able to transfer a lot of them and then suddenly I received an error code telling me its 'impossible to move a file to the destination folder because there is not enough available space'. I am on iMac with latest version of OS. Find below the french dialog box with the error code. I have translated it for this purpose. I have 500g still available on my disk so don't think this is the issue. Would really appreciate understanding how I can fix this. Thank you.
