Q: When I used Windows XP, because the word on the display was small, I downloaded the novel to the local hard disk, then modified the source file, and then enlarged the font. Now I bought a new computer, pre-installed Windows 7 Home Basic Edition, but found that the file properties have been read-only, can not be modified, how to modify the file properties in Windows 7 Home Basic Edition?

A: If you have a lot of source files, you can put them in the D:\\books path. You can click “Start →Accessories", and find the "command prompt> Right-click and select “Run as administrator" Open a command prompt and type the following command:

attrib -rd:\\books\\*.*

Change the properties of these source files.
