dos show all filenames, dos filenames, naming conventions?

In Runtime, enter cmd. For example, if you want to get all the files and folders in the root directory of the D drive, and you want to display all the file names, use dir d: a x to show the corresponding alternate paths elsewhere.

To put it simply, it's dir a

For details: dir [drive:][path][filename] [ a[[:attributes]] b] [ c] [ d] [ l] [ n].

o[[:sortorder]] /p] [/q] [/r] [/s] [/t[[:timefield]] /w] [/x] [/4]

drive:][path][filename] specifies the drives, directories, and or files to list.

a Displays files with specified attributes.

Attribute d directory r read-only file.

h Hide File A file ready for archiving.

s System file i No content index file.

l Resolution Point - A prefix that means "no".

b Use empty format (no header information or abstract).

c Displays a thousands separator in the file size. This is the default value. Use -c.

Disables the display of separators.

d is the same as width, but the files are listed by column.

l in lowercase.

n New long column ** with Chinese name on the far right.

o List files in categorical order.

Sort order n by name (alphabetical) s by size (from smallest to largest) e by extension (alphabetical) d by date and time (first to last) g group directory precedence - prefixes in reverse order.

p Pauses after each information screen.

q Displays the owner of the file.

r Displays the alternate data stream for the file.

s displays files in the specified directory and all subdirectories.

t controls the time character range that is displayed or used for classification.

Time period c Creation time.

a Last visit.

w The time of the last write.

w with wide column**.

x appears as a short name generated by a non-file name. The format is n, with the short name inserted in front of the long name. If there is no short name, then in its place.

Blank is displayed. 4 Displays the year in four digits.

The format is the file naming rules under DOS: the main file name cannot exceed 8 characters (or 4 Chinese characters if it is Chinese), and the extension name cannot exceed 3 characters, separated by .

When converting long file names from Windows to 8 3 format, the approximate method is as follows: Take the first 6 characters of the file name, plus 1 (if the first six are the same, use 2 and 3 in order.)

Use the first 3 characters of the content after the last dot as the extension. The format of 8 3 for the Chinese People's Liberation Army 2000 doc should be: Chinese 1 doc

There is no way to know the number of noisy blocks under pure DOS, because pure DOS does not support long folders or file names.

The English symbol is called tilde, which means palate symbol, nasalized symbol, code number), and in Chinese it is commonly known as tilde. is a punctuation mark that has many uses.

It is a letter used as an abbreviation, but it is also used as a diacritic or a single character. Mathematically, it is a mathematical symbol that represents an equivalence relationship. In the last use (especially in lexicography), it is sometimes used as a code.

Operator notation. Arithmetic operators.

It is used for all kinds of numerical operations. Including addition (+) subtraction (-) multiplication (*) division ( ) remainder (or modulo operation, %) self-increment (++ self-subtraction (--, a total of seven kinds.

Relational operators.

Used for comparison operations. These include greater than (>), less than (<), equal to (==disturbance, greater than or equal to (> = less than or equal to (< = and not equal to (!= Six kinds.

Logical operators.

Used for logical operations. Includes those related to (&& or (||Non (!.)Three kinds.

Bitwise manipulation operators.

The amount of money involved in the operation is calculated in binary bits. Include bits with (&) bits or (|.)) bit non ( ) bit XO or ( ) left shift ("Right shift (>> six kinds.

View via the "type" command.

Usage 1: Direct "type e: absolute path".

Usage 2: If it is in a relative path, you can directly "type".

Note: The DOS window can only open files similar to notepads, if the file type is not recognized, garbled characters will appear.

For files that can be used, you can use the form type, such as "type", which will display the contents of the file in the command line interface. For non-text files, garbled characters are displayed.

The dos command can only display files that can be opened with Notepad, such as txt and bat.

The file name under DOS is generally a formula, which means that the file name is 8 characters and the extension is 3 characters. File name OK.

In any, but not in the following characters:"<、>/、"、.and spaces". Extension decision.

File type.

formula, which means that the file name is 8 characters. The extension is three characters.

The main file name can be up to 8 letters and the extension can be up to 3 letters.

Letters, numbers, and case insensitivity can be used.
