Description of Windows attribute symbols

Folder attributes include none, H, HS, HSA, R, Ra, Rh, and RHA.
File attributes include a, Ra, RSA, and rhsa.
H-hide, S-system, R-read-only, and a-archive.

To change the properties of a file, use the DOS command.
For example, I create an O. txt file under drive G.
Then, I enter the DOS interface and go to the G-drive root directory.
Use the attrib + A + S + H o.txt command
The file o.txt has the HSA attribute.
Use the command> attrib-a-s-h o.txt
The file o.txt eliminates the HSA attributes.
Do not forget to mark the file after the command, otherwise it will operate on another file by default

Attrib-Annotation

Hide the combination of attributes and system attributes

If a file has both hidden and system attributes, you can use an attrib command to delete these attributes at the same time. For example, to delete the hidden and system attributes of the record. txt file, you can enter:

Attrib-s-h record. txt

 

Apply attrib to a group of Files

Use wildcards (? And *) to display and change the attributes of a group of files at the same time. If a file has a system or hidden attribute, you must clear it before changing other attributes of the file.

 

Change directory attributes

You can display or modify the directory attributes. Attrib is used for a directory. The directory name must be clearly specified, and wildcards cannot be used. For example, to hide the directory c: \ secret, enter the following command:

Attrib + H c: \ secret

The following command only applies to files and does not affect directories.

Attrib + h c :*.*

 

View archive attributes

Archive attribute (a) is used to mark the files changed after the last backup. These archive attributes are used by msbackup, restore, and xcopy commands. For more information about archive attributes, see:
<Msbackup>, <restore>, and <xcopy>

Attrib-Example

Run the following command to display the file attributes named news86 on the current drive:

Attrib news86

Run the following command to assign the read-only attribute to the Report. txt file:

Attrib + R report.txt

Run the following command to delete the read-only attribute from the file attributes in the directory \ public \ Jones and Its subdirectories on disk B:

Attrib-r B: \ public \ Jones \ *. */s

In the last example, we assume that you want to operate all the files in the default directory of disk A (except for. BAK files ). Because <xcopy> is used to copy objects marked with the archive attribute, you need to set the archive attribute for the objects you want to copy. This can be done with the following two commands. It first sets the archive attribute for all files in drive a, and then deletes the archive attributes of files with the. Bak extension:

Attrib + :*.*

Attrib-A: *. Bak

Then, use the xcopy command to back up the file on disk A to disk B. The/a switch indicates that xcopy only backs up files with archive attributes:

Xcopy A: B:/

To delete the archive attribute of an object after each copy, you only need to switch/a to/M. For example:

Xcopy A: B:/m
