- File retrieval: It offers effective file-searching techniques and enables users to look for and retrieve certain files based on their names, properties, or contents.
- File modification: The file management system enables users to edit the contents of already-existing files, add new data, or replace already-existing data in the files.
- File deletion: It enables users to get rid of files they don’t need anymore, clearing up storage space and controlling disk utilization.
- File sharing: The file management system enables simultaneous access to files while protecting the integrity of the data, allowing file sharing across several users or processes.
- File backup and recovery: In the event of an unintentional loss, hardware problems, or system crashes, it contains techniques for backing up and restoring crucial files.
- Security and file protection: The file management in operating system employs security features including access restrictions, encryption, and file permissions to safeguard sensitive data and thwart illegal access.
- File metadata maintenance: It keeps track of file metadata, which includes characteristics like file size, creation/modification timestamps, ownership details, and file permissions.
Components of File Management in Operating System
The following is a list of the operating system’s file management in operating system’s components:
File Attribute
It describes file attributes like type, most recent modification date, size, placement on disk, and so forth. The user can better understand the purpose and placement of files thanks to file attributes. It is employed, to sum up all the details about a certain file.
File Operations
It outlines the possible operations on a file, including opening and shutting.
File Access Permissions
Access permissions for files are clearly defined in this specification. And include crucial functions like reading and writing. As such obtaining proper authorization beforehand is critical for accessing any given file.
File Systems
It describes the logical way that files are kept in computer systems. Two of the most widely utilized file systems are FAT and NTFS.
Operations on File Systems in Operating System
Operating systems’ file systems offer a variety of actions for effective file management in OS. Typical file system operations include the following:
-
Create
A new file is made with this method. It entails creating the initial properties or information as well as providing space for the file and giving it a distinctive name.
-
Open
An existing file can be accessed using the open function for reading, writing, or both purposes. Creating a link between the file and the process enables later file activities.
-
Read
Data from a file is retrieved using this method. It reads a certain number of bytes from the file into memory or a buffer for further processing.
-
Write
Data is stored in files using the write procedure. It adds a certain amount of bytes from memory or a buffer to the file, either overwriting previously stored information or adding it to the end.
-
Close
To cut off communication between a file and a process, the closure operation is carried out. It guarantees that all modifications to the file are preserved and that all system resources devoted to the file are freed.
-
Delete
A file can be deleted using this procedure from the file system. It releases the file’s storage space and permanently deletes it from the directory hierarchy.
-
Rename
A file’s name can be changed using the rename method. The directory entry for the file is updated to reflect the new name.
-
Seek
The seek action enables the file pointer to be moved to a certain location inside the file. It permits arbitrary access to various file locations, allowing effective reading or writing tasks.
-
Truncate
This procedure is used to make a file smaller. It truncates the file by removing all data past a certain point.
-
File Attribute Modification
Operations to change the file’s metadata, including its rights, ownership, timestamps, and other properties.
