Do shapefiles have a projection?
To re-project a shapefile, the defined projection must first be known. A. If you do not know it, and it is displayed as unknown in the properties box, or its is displayed as unkonw when you go to “Project” it, then you will have to figure this out first.

What is a shapefile used for?
A shapefile is a vector data file format commonly used for geospatial analysis. Shapefiles store the location, geometry, and attribution of point, line, and polygon features.
How do I open a shapefile in Excel?

What is the difference between the project and define projection tool?
Which tool is the one for you? If your data doesn’t have a coordinate system, or you suspect it has the wrong one, you want Define Projection. If your data already has a coordinate system but you wish to convert it into a different one, you want Project.
What is the difference between geographic and projected coordinate systems?
A geographic coordinate system (GCS) is a reference framework that defines the locations of features on a model of the earth. It’s shaped like a globe—spherical. Its units are angular, usually degrees. A projected coordinate system (PCS) is flat.
How do I reproject the CRS of the second shapefile?
To reproject the CRS of the second shapefile, we will need to export the shapefile to a new file using the project CRS. To start, right click on the shapefile and select Export –> Save Features As In the Export screen, type in a new shapefile name and click on the three dots next to the File name box to select the folder.
Can I export a shapefile to another projection system?
If you know the starting coordinate system or projection of your shapefile, you can quickly export the data into another coordinate or projections system using QGIS. What Files Are Needed to Reproject a Shapefile?
How does QGIS assign the projection system to a shapefile?
When you include a .prj file, QGIS will automatically assign the proper coordinate or projection system to the shapefile. A fresh QGIS project will be assigned the Coordinate Reference System (CRS) for the first geographic file that is loaded.
How many files does a shapefile have?
At a minimum, a shapefile will have three files. The file with the extension .shp contains the geometry information. The .shx file is the index file and the .dbf file contains the attribute information that is attached to geographic information. Shapefiles may have additional files associated with them (More: What is a Shapefile? ).
