Most of the Microsoft product files are stored in a cabinet (. Cab) after being compressed, and therefore to use a file in .Cab file, the files need to be extracted first. Also a new copy of files is required to be extracted to the windows access file, if there is already a missing or damaged file.
All the previous version of windows other than the currently used windows version, contain compressed cabinet files which are also installed in the C:\Windows\Options\Install folder. The cabinet files thus contain the actual windows files. It is very much pertinent here to understand that how computers and their files interact and how to make a windows access.
The operating system of computer which is windows and all other programs that are installed on it comprise sole files. Most files are placed in the directories or folders. These directories or folders work as a filling cabinet.
Many files related to the windows access in a folder are called Windows. In windows access the folder is many subfolders that are divided into more files. On the other hand the files that do not reside on a folder or sub folder are found on the root of the drive. The real name thus of Windows subfolder can be different in several systems as in Windows XP operating system, the windows access folder may be named as Win XP.
It is due to this reason that %windir% is mostly used in the technical writing as the name of the Windows folder. Since these are securable objects, approach to windows folder is controlled by the access control model which operates access to all other sensible objects in Windows.
A security descriptor can be specified for a file whenever you say the CreateFile or CreateDirectory function. If null is specified, the file owns a default security descriptor. The access control lists pertaining to the access of Windows files, in the default security descriptor for a file transfer from the corresponding parent directory.
It must be noted that default security descriptor is given when a file or directory is recently created, not that time when it is moved or renamed. The valid Windows access file rights include Delete, Read_Control, Write_Dac, Write_Owner and Synchronize, which are often referred to as the standard access rights. The listed table in the File access Rights Constants lists the access rights which are particular to the files and directories.
The synchronize access rights are defined as standard access rights list as the duty to clarify a file control in one of the functions in the procedure for Windows access. Therefore while applying asynchronous files Input/output operations one must watch away on the active control contained in a well designed overlapped structure instead of using the file handle with the synchronize access right for synchronization in Windows access. Windows then contrast the demanding access rights and the data in the thread’s access token with the data in the file object’s security descriptor. If the all of the demanding access rights are not prohibited from requesting windows access rights from being accepted by the comparison a control to the object is turned to the thread and the access rights are accepted thereby.
