Also TRUENAME does not search in the PATH. For example, in DOS 5, if the current directory is C:\TEMP, then TRUENAME command.com will display C:\TEMP\COMMAND.COM (which does not exist), not C:\DOS\COMMAND.COM (which does and is in the PATH). This command displays the UNC pathnames of mapped network or local CD drives. This command is an ...

Some versions of DOS do not assign the drive letter, beginning with C:, to the first active primary partition recognized upon the first physical hard disk, but on the first primary partition recognized of the first ...

[36] 32X – Sega 32X; 3DS – Nintendo 3DS; A26 – Atari 2600; A52 – Atari 5200; A78 – Atari 7800; ADF – Amiga (.adf) (for 880K diskette images) ADZ – GZip-compressed version of the ...
Formatting a disk for use by an operating system and its applications typically involves three different processes. [e]Low-level formatting (i.e., closest to the hardware) marks the surfaces of the disks with markers indicating the start of a recording block (typically today called sector markers) and other information like block CRC to be used later, in normal operations, by the disk ...
In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
In addition "\" does not indicate a single root, but instead the root of the "current disk". Indicating a file on a disk other than the current one requires prefixing a drive letter and colon. No ambiguity ensues, because colon is not a valid character in an MS-DOS filename, and thus one cannot have a file called "A:" in the current directory.
Some people use the term filename when referring to a complete specification of device, subdirectories and filename such as the Windows C:\Program Files\Microsoft Games\Chess\Chess.exe. The filename in this case is Chess.exe. Some utilities have settings to suppress the extension as with MS Windows Explorer. [not verified in body]
Closed data file formats, frequently referred to as proprietary format files, have their metadata data elements hidden, obscured or unavailable to users of the file. Application developers do this to discourage users from tampering with or corrupting the data files or importing the data into a competitor's application.
