That's very unfortunate error.
I wonder if you still have the version that you used to create the flow installed? If not, could you install it again (you can have multiple Prep versions installed just like Tableau Desktop)? Maybe you could open this in the original version and try to use it there (maybe re-saving there it will unlock the error?)
Let me know if this helps
I installed Prep 2018.1.1 in May 2018 - first use of the app
In Sept 2018, i upgraded to 2018.2.3, and uninstalled 10.1.1.
I've only used 2018.2.3 since Sept.
This flow was only recently created (in Dec), using my currently installed 2018.2.3.
Thx for the suggestion -
Hi Luke, just checking if there was an update on that Support ticket you raised?

As of this morning, still with Tier-2 support. I would be interested if you've seen this error? I can't see that I did anything different when saving this time. I have now found 3 twb's that became corrupted with the same error message. Others on my team mentioned they've experienced it and had to recover the files to get beyond it. Thx!!
I have just come across the same problem this morning. Did you ever get an answer back from Tableau?
Quick update- It looks like in some scenarios, specifically when you are using a version of Prep that is valid, and has previously opened this file, and the file is saved on your local computer, You may be able to resolve this issue by Using 7.zip to extract the flow folder, and then re-zip the folder, changing the extension back to .tfl. It looks like this has fixed a few scenarios. However, It looks like when the file is being kept on a shared drive, this is less likely to work, as the corruption is likely to be caused by a "blip" in the network while saving. Network drives are known for causing similar issues, and it's not something Tableau would be able to fix, as it's all about how the operating system and network handle the file transfer.
If you are saving your flow to a shared/network drive, Please keep a local copy as well so that you have a backup if something like this occurs! Hopefully that helps someone!
This is a horrible error. Is there any way to rebuild these files? 7zip is not able to extract the Flow file.
This is absolutely devastating!!!
