no, it isn't :(
These characters here: \ / " * ? < > | Everything else is fair game.
a file name can contain any type of character, it can be start from any character,number& can start with symbol also.
Behavior
The asterisk is a special character and cannot be used in the names of any kind of file.
A: an ****** or a ?????? Is usually accepted
it is a wildcard for each unknown letter in a command. If you want to find all files in a directory that start with a and have a three letter file extention, you would use the command dir a*.???
An invalid file name is one that contains characters or formats not permitted by the operating system. For example, in Windows, file names cannot include characters like \ / : * ? " < > |. Additionally, names that are too long or use reserved names (like "CON" or "PRN") are also considered invalid. Each operating system has its own rules governing valid file names.
No, "FILE NAME TEXT" is not a valid name for a C source file. C source files must follow specific naming conventions, which typically allow only alphanumeric characters, underscores, and dots. Spaces and special characters are not permitted in file names. A valid C source file name would look like "file_name.c" or "fileName.c".
the question mark is a wild card for one character if you do not know what letter or number it should be
It's a wildcard which means any single character. For instance: > dir ???.txt This will list all 3-letter file names that have a .txt extension in the current folder. An asterisk can also be used as a wildcard and represents any group of characters. > dir *.txt This will list all file names that have a .txt extension in the current folder.
The operating system that typically allows for the smallest file names is Unix-based systems, including Linux. These systems can accommodate file names as short as one character, such as "a" or "1." However, it's important to note that while Unix/Linux systems support short names, the minimum length can also depend on the specific file system being used. In contrast, Windows requires at least a three-character name due to its default file naming conventions.
Yes it is a valid name..
