I was working on a ArcGIS 10.1 custom toolbox with several modelbuilder models. It was going well, but I think my harddrive containing the model accidentally was removed and corrupted the toolbox as it no longer shows the models within it when opened in ArcGIS toolbox. Is there a way to repair corrupted toolboxes? Or is it possible to open the .tbx in a text editor or something to at least view the steps of the models so I can at least remember the steps of each model so I can recreate the models in a new toolbox? The .tbx still shows it is 1,818 KB in size so seems like the models are still saved in there, but just can't figure out a way to access them. Thanks in advance.
