HTML5 File API aspect provides an API for representing file objects in web applications and programmatic selection and accessing their data. In addition, this specification defines objects to be used within threaded web applications for the synchronous reading of files.
Read-only (R): When set, indicates that a file should not be altered. Upon opening the file, file system API usually does not grant write permission to the requesting application, unless the application explicitly requests it. Read-only attributes on folders are usually ignored, being used for another purpose. [5] [6]

When set for a directory, this permission grants the ability to read the names of files in the directory, but not to find out any further information about them such as contents, file type, size, ownership, permissions. The write permission grants the ability to modify a file. When set for ...
Some early operating systems were capable of handling only tape and disk file systems. These provided the most basic of interfaces with: Write, read and position; More coordination such as device allocation and deallocation required the addition of: Open and close; As file systems provided more services, more interfaces were defined:
In Microsoft Windows, a resource is an identifiable, read-only chunk of data embedded in an executable file—specifically a PE file. Files that contain resources include: EXE, DLL, CPL, SCR, SYS and MUI files. [1] [2] [3] The Windows API provides a computer program access to resources.
File locking is a mechanism that restricts access to a computer file, or to a region of a file, by allowing only one user or process to modify or delete it at a specific time, and preventing reading of the file while it's being modified or deleted.
An RW lock allows concurrent access for read-only operations, whereas write operations require exclusive access. This means that multiple threads can read the data in parallel but an exclusive lock is needed for writing or modifying data. When a writer is writing the data, all other writers and readers will be blocked until the writer is ...
In computer technology, read-only can refer to: Read-only memory (ROM), a type of storage media; Read-only access to memory using memory protection; Read-only access to files or directories in file system permissions; Read-only access for database administrators in database system permissions
