However, not all files can be done with del command, such as files with hidden attribute, read-only attribute or system attribute\ test.txt It has a hidden attribute, if only del D:\ test.txt If so, D:\ test.txt It’s going to stay still. How to delete it? At this time, you need to add some auxiliary parameters to del. The hidden attribute is hidden, use del / A: H, the read-only attribute is read, use del / A: R, the system attribute is system, and use del / A: S. if you don’t know what the file attribute is, then you can use del / a – except in one case, when the file has the read-only attribute, you have to add del / A / F Therefore, if you want to delete the files that do not know the attributes, the Del / A / F statement is the safest way. Here, the / f parameter means to force the deletion of the read-only attribute file. F is taken from force, which means force.
