Most Mac users know and understand folders. This is where we and Mac OS X hold files. The folders we notice most include Documents (a convenient folder for saving personal files), Music, Pictures, and Movies. For each user there is also a download folder, and Mac's desktop is actually also a folder.
The Mac itself keeps system files in different folders and, as it should be, not easily accessible. What if you want to see where all your Mac folders are and how many files and folders are in how much disk space they record?
Finder can help, but it's some of a manual process to use Finder to dig through your files. If you have some money to burn, and you are curious about which files and folders are sucking up your entire storage on your Mac, try Folder Size Catalog.
As this required the design of the tool name, it scans the folders on your Mac and displays them directory style so you can see what's what. Large folders, subfolders, and folder sizes.
Depending on the number of folders and files on your Mac, Folder Size Catalog can take a few minutes to scan each file. With an option, you can increase the speed of the scan process by skipping smaller images. If you want to search through specific folders, such as the user's home directory, Folder Size Catalog can also do that.
Finally, you get a different look at the folders and files on your Mac than usual with other scanning tools. Folder Size Catalog will display necessary details, including the date of scan, scan path, total number of folders indexed, and then a list of folders, including file size and path, plus an option to display the folder with a click.  This method is far faster than using Mac Finder, and the output is an HTML5 mobile friendly directory file that can be stored and shared with others. The price is about average for a folder scanner.
