Hi,

I once tried to open an 8 GB .lp file. My system hung, and the editor occasionally crashed. Even files around 1 GB feel slow to open.

I was wondering if this is a common problem, so I'd like to understand a few things:

1. Do you open .lp files to understand or debug your models? If so, what tools do you use?
2. How often do you encounter large .lp files? By "large," I mean files that take a long time to load, cause your system to hang, or crash your editor. If you remember the file size or model size (number of variables, constraints, and nonzeros), please share.
3. Does anyone work with mathematical models and solvers without ever needing to open or inspect .lp files?
