Anyone here still familiar with the old Visual Studio 2003 C++, or am I the only one still using it?

I am recovering from a crash that put me "out of biz" for several days but I am finally beginning the recovery. I have a question re the VC++ 2003 environment.

Problem #1 - When asked to compile files that compiled successfully prior to crash, the compiler not only won't compile them, it won't even open them.

The project/source files have been restored in mirror-image (i.e. right off the DVD storage) just as they were prior to crash, with the same project and folder name (i.e. projects 'reminder', 'HexDump', etc in folder 'CPP'), but the compiler refuses to take any action in response to 'build' command.

Now, by creating a NEW project of the same name in the NEW folder of the same name (i.e. new project 'reminder' found in new folder 'CPP' as before), and by cutting and pasting the code from the old files to the new, the compiler is satisfied with my build request and re-compiles satisfactorily.

So obviously, I can get around this problem simply by cutting and pasting files from old to new, but I really shouldn't have to do that. Is there some slick way I can throw a switch or enter some command that will permit the compiler to compile the existing code rather than 'tricking' the compiler into thinking it's working on a new file?

Thanks for your help.
