ArcCatalog - Overview
ArcGIS is the name of a suite of software, all accomplishing something different with spatial data: organization, analysis, and exploring 3D data. In GIS 101, you will be exposed to two of the software found in that suite: ArcCatalog and ArcMap. ArcCatalog can be described as the "File Explorer of Spatial Data" while ArcMap is the software we use to interact with and explore our data, both spatially and in table form.
Each software in the ArcGIS suite has am almost identical layout, with a series of menus along the top, several shortcut buttons below that, some thin columns on the left which show the data or folders which are saved in some specific folder or are participating in the project, a large area on the right where the user interacts with their data directly, and some docked tabs hiding some additional tool boxes or resources. Having the same basic layout in each software makes navigation a whole lot easier when going between each software.
In the figure below, we a screenshot of ArcCatalog, and we know it's ArcCatalog because the very top of the window has an image of the software icon and the path of the folder which is open in the main area of the ArcCatalog window. Below that, we have the menu bar, which has a series of menus - ones you might expect with a Windows-based software such as "File", "Edit", and "Help", and ones which are most likely very new to you like "Geoprocessing" and "Go". As we work with ArcCatalog in lab, these menus will slowly become more familiar. Below the menu bar, we see some toolbars, specifically the Standard Toolbar, which contains buttons to explore our data and show/hide some of the side windows in ArcCatalog, and the Geography Toolbar, which contains buttons to interact with your spatial data in a spatial way like zooming and panning.
Along the left side of the window, we see the Catalog Tree, a list of all the folders and spatial files. To the left of each folder, we can see a + and - sign, the plus sign showing a folder which is collapsed and contains data and a minus sign next to folders which are expanded and showing their contents. From the catalog tree, we can rename, delete, copy, paste, and rearrange spatial data one file at a time.
To interact with more than one file at a time, we need to use the Contents Panel. This area shows the contents of whichever folder is highlighted in the Catalog Tree. In this example, we can see that "Original_Data" folder both is highlighted and expanded in the Catalog Tree. From the file expansion, we see there is one the file icons for a geodatabase, a polyline, a point, and a polygon shapefile - the same view as inside the Contents Panel. The Location Toolbar, outlined in a green color above the Contents Panel, shows the complete path of the data shown in the Contents Panel and what is highlighted in the Catalog Tree.
|ArcCatalog's Basic Layout|
ArcCatalog is like the ‘File Explorer’ of the ArcGIS software suite. Having a data management software specifically designed for spatial data allows us to see spatial data a single files instead of the several part they are made up of. ArcCatalog recognizes these individual files as all being part of a single file, thus displays it that way.
When we look at spatial files in File Explorer, we see examples like the following screenshots

Using File Explorer to copy/move/delete geodatabase files or shapefiles can lead to mistakes if one fails to copy all of the files associated with a spatial file. Thus, a ‘good practices’ habit to get into is using File Explorer when zipping or moving entire folders of spatial data, and using ArcCatalog for moving everything below the folder level.
