The default attributes of files created by users in Windows are archive attributes.
In Windows, the attributes of a file include read-only, hidden, system, and archive. The archive attribute (archive) refers to one of the attributes of a file or folder (hereinafter referred to as a file) that can be used to mark. Common file attributes include system attributes, hidden attributes, read-only attributes and archive attributes.
The "archive" attribute of files in windows involves its own backup tool ntbackup. Its backup principle is based on the status of the file backup mark. The backup mark is an attribute of the file, also known as the archive attribute. There are two statuses of archive attributes: backed up (not checked) and not backed up (checked).
The corresponding explanation is that if it has been backed up by the ntbackup tool, it will be marked as "backed up", otherwise it will be marked as not backed up. If the backed up files and folders are modified later, the system will automatically mark the file or folder as archived, indicating that the file or folder will be backed up in the next backup.
Of course, you can also add the archive attributes manually, but it also involves the backup type of ntbackup, so I won’t go into details again. In short, regarding the archive attributes, all files supported by the Windows system will have them for backup, but Whether it is activated or not (whether it is checked or not depends on whether it has not been backed up using ntbackup, as well as the backup type used at that time.
