System File Checker (SFC [1]) is a utility in Microsoft Windows that allows users to scan for and restore corrupted Windows system files. [2] Overview.
DirectX Diagnostic Tool (DxDiag) is a diagnostics tool used to test DirectX functionality and troubleshoot video- or sound-related hardware problems. DirectX Diagnostic can save text files with the scan results. These files are often posted in tech forums or attached to support emails in order to give support personnel a better idea of the PC ...
A system file in computers is a critical computer file without which a computer system may not operate correctly. These files may come as part of the operating system, a third-party device driver or other sources. Microsoft Windows and MS-DOS mark their more valuable system files with a "system" attribute to protect them against accidental ...
System Information (msinfo32.exe) is a system profiler included with Microsoft Windows that displays diagnostic and troubleshooting information related to the operating system, hardware and software. [1][2] It has been bundled with Windows since Windows NT 4.0. It compiles technical information on the overall system, hardware resources ...
File integrity monitoring (FIM) is an internal control or process that performs the act of validating the integrity of operating system and application software files using a verification method between the current file state and a known, good baseline. This comparison method often involves calculating a known cryptographic checksum of the file ...
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems. First included in Windows Me, it has been ...
open (system call) For most file systems, a program initializes access to a file in a file system using the open system call. This allocates resources associated to the file (the file descriptor), and returns a handle that the process will use to refer to that file. In some cases the open is performed by the first access.
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum. This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files. A more popular approach is to generate a hash of the copied ...
