These files are produced as the output of the compiler. They consist of function definitions in binary form, but they are not executable by themselves. Object files end in ".o" by convention, although on some operating systems (e.g. Windows, MS-DOS), they often end in ".obj".
The Java.io.File class is an abstract representation of file and directory pathnames. Following are the important points about File:Instances may or may not denote an actual file-system object such as a file or a directory. If it does denote such an object then that object resides in a partition. A partition is an operating system-specific portion of storage for a file system.A file system may implement restrictions to certain operations on the actual file-system object, such as reading, writing, and executing. These restrictions are collectively known as access permissions.Instances of the File class are immutable; that is, once created, the abstract pathname represented by a File object will never change.
It is poor programming practice resulting in undefined behaviour. Files should never store memory addresses (real or virtual), since there's no guarantee a valid object will always reside at the same location in memory, unless the programmer can be absolutely certain the object will outlive the file (such as when referring to active objects in memory via a temporary file).To embed an object in a file, the object must be stored in an independent file. The file in which the object is embedded simply links to the object's file. In this way, whenever the object is updated (and saved), all files in which it is embedded will also be updated.

In computer science, an object file is an organized collection of separate, named sequences of machine code.
why does a program consists of more than one object file in c++
No. A file is a single object that contains unstructured data, such as a letter in Microsoft Word or an picture in a JPG File. A database is a structured collection of fields, records and tables stored in a way that allows rapid access.
The file extension for Microsoft Access 2007 is '.accdb'.

The file's owner can access it.

Because a linked object is created and stored in a separate source file and then it is linked to the destination file, while an embedded object is created in a separate source file but then it is inserted into the destination file , becoming the part of that file.

The common techniques of file processing include sequential access, random access, and direct access. Sequential access involves reading data sequentially from the beginning to the end of a file. Random access allows reading data from any part of the file without having to read the preceding data. Direct access uses a key or address to locate specific data within the file.
A serial access file has data stored on it in the order in which it was written. Each new record goes at the end of the file. To read a record from the file it is necessary to read through all the preceding records first.A sequential access file has data stored on it in the order of the data in a key field.A direct access file is one where any record can be accessed without having to access other records first. This is also known as random access.
