File count discrepancy

[MCTaylor17]

I ran sloc on Cypress.io 3.1.4 pre-npm-install and got the following results:

---------- Result ------------
Physical : 181219
Source : 131887
Comment : 17028
Single-line comment : 12828
Block comment : 4200
Mixed : 1907
Empty block comment : 111
Empty : 34322
To Do : 180

Number of files read : 1174

Right-click Window10 properties on the folder shows 1422 files and and 327 folders. That's 248 files less than the results. Are those all README.md and data files?

If this is expected, It would be helpful to have an explanation in the README.
