I created a file yesterday, saved it and then closed Dn. I tried to open it this morning (computer was left on) and I get the error message stated in the subject line. The file is not missing as you will see in the screenshot but I am unable to open it. Have tried double clicking the file, using file open and navigating to the file.
This has been the case for all Dn files I have created (3 total:). The work around I have found is to create a new file and import the file as a 3D model (file "...Stacked2" in the screenshot). From there I am able to continue working. The new file will even show up in the "Recent" list after closing but it seems to be the trend that after a day has passed Dn no longer recognizes the file.
Grateful for any help!

are you saving files to a temp folder perhaps like the desktop?
That seems to be my issue!
We work from a shared cloud drive here in the office and any file I save to that directory gives me the error message. I saved out samples to other places (local desktop, Onedrive, Creative Cloud Files folder, etc) and they all opened without a problem.
