I have been doing it like this since I started using Portfolio Performance. It is the format that Interactive Brokers gives you.
I update the data in the PP every other week, and today when I opened the program it asked for an update. I did it and now it is when it seems that it does not work.
Then please open the file with a text editor and show me the first few lines. Your screenshot says PP(1) is of the type: Microsoft Edge HTML Document and HTML isn’t XML.
That’s really strange, because it’s really looking like an XML file from the structure. Maybe Windows isn’t getting the type correct, because the XML headline is missing.
I also don`t understand why the default is to hide known file extensions. I always turn on “show file extension”, when I setup a new Windows machine, because I want to know which kind of file type I`m about to open.
You’re right, I also turn that on. But I wasn’t aware that the type indicated on the hover information isn’t the same! Thank you for the learning moment!
