I'm not sure this is a bug. You generally don't have to have the extension. When you open remote the example shown is fmnet:/hostIPAddress/fileName. The same goes for the examples in Edit Data Source. Notice none of them have the actual file extension. You can put them there but they are not required.
Well, if we take my screenshot examples, both file are in the same folder, the difference is their extension. How does FileMaker know witch one I want?
And I stumble upon that bug when trying to import data from a runtime database with the extension USR and was asked for the file, but it was there. After specifying the extension in the data source (after FileMaker deleted it when converting), the importation went well without FileMaker asking for the file.
Oh, I see that you are using a file that's either had it's extension renamed or has go through the Developer Utilities. I see you problem. In that case they would be considered the same.
Have you gone back in and added the extensions after the fact? That just worked for me.
As I said, adding the extensions back do work, but why would FileMaker change the data source when converting to fmp12.. to me it just does not make senses.
I like to rename file extensions so I can have mutiple files with the same name in the same folder but with differents extensions to differenciate them, or just changing the extension for fp7 to usr manualy so it doesn't open FileMaker when double clicking it but still work completely as a FileMaker database..
I think they made an assumption that no one was using other extensions.
Thank you for your posts.
I have forwarded your posts to our Development and Testing departments for review. I will keep you updated as information becomes available to me.
In the mean time, you will need to revisit the data source listings and add back the extensions for files without the .fmp12 extension.
