I saved a SAS EG 7.1 file with years worth of information. Many Process Flows with dozens of program code files. The size of the EG file is 571 KB, but when I open the EG file it is empty except for the names of the Process Flows. Nothing else, none of the program codes or any other information is showing.
This has happened for both my primary working file and my backup file.
Is there a way to recover previous version?
Also, why is this happening??
If you change the extension to .zip, you can see the contents.
That is a massive project. I would suggest breaking it up somehow.

I am speculating here so bear with me. The EG guys can correct if I miss something.
EG is a .NET/C# app (I am a SAS and C# dev so I kind of know how this works). When you make changes to an EG project, it saves them to the in-memory object (classes). When you save, it has to serialize them to XML. When you open a project, it deserializes them back to the objects. Any time you are serializing a large object, it can go wrong. Shouldn't, but it can. depending on what happens in the I/O. Especially true over a network connection. I suspect something blipped in the serialization.
You really need to make the project smaller. I have never seen an EG project of that size and I look at them a lot, especially in their raw form. I rarely use EG as an application, mainly deal with the EG zip file or making EG add-ins. If you have data stored in the project (which I suspect), move it elsewhere.
If you really want to make your EG project work super secure then it's well worth your while using EG's Git version control functionality - you'll probably need to upgrade to a later EG version to make best use of that. If anything gets corrupted you have a complete history of all previous changes to go back to. So you can track any change you've made as well as having secure backups in case anything goes pear-shaped.
How did you do after changing .egp to .zip?
