Tutorial - How to Scan Drive?
Introduction
Free Duplicates Finder also brings convenience to scan your hard disk for disk space analysis. With a graphical diagram, you can clearly view the disk space occupied by each folder or file and easily find the file which takes bigger space and then delete it to save more important files if possible.
Scan Drive
Launch
Free Duplicates Finder. Click the disk you want to search for the
duplicate files. If you only want to search a certain folder,
navigate to it and single click the folder to select it. Click the
"Scan Drive" button in the top left corner of the
window, and it will start scanning your computer
for existed files and folders. 
Depending
what search criteria you chose, this process takes a few seconds
to complete. When it is finished, it will list all the files
and folders in the graphical form with sizes and color
bars displayed. Click "Delete..." to delete the
single file. Click "Send Email..." to send the
detailed info of selected files and folders. You can change
the color of the bar through "Options".
For detail info, please check (How to Set Search Option?). Click
"Run..." to directly open the file or folder.
