How to tell if a path is a directory or a file

The thirteenth findfirstfile looks for the file and gets the information of the file.

Let's take an example to list all the files in the first directory of the E drive, including folders, and combine them with FindNextFile

#include

#include

intmain()

booldone=true;

win32_find_data

fd;handle

hfindfindfirstfile("e:\\",fd);The first parameter is the pathname, which can use wildcards, and people who know DOS should know it! FD stores information about the file.

whiledone)

printf("%s",;

done=findnextfile(hfind,fd);If the returned value is 0, there are no files to find.

return

Of course, you can also just find a file and don't use wildcards, but what's the point? , such as this can actually get information about a file, such as whether the file is hidden, or whether it has read-only attributes, etc.

Of course, by controlling wildcards, you can also look for specific types of files, for example, I only need to find text files, then this statement findfirstfile("e:\\txt",&fd);That's it, it's up to you to use it flexibly.

As mentioned earlier, there is information about the file stored in the fd, so how to judge the properties of the file according to the members in the fd, whether the file is hidden, whether it is a folder.

The dwfileattributes in the fd store the information of the file, such as judging whether it is a folder, as long as this variable and the file attribute directory are bitwise and arithmetic, if it is 1, it indicates that it is a document folder, such as.

printf("%s is the folder",;

The same is true for other judgments, now give the file attribute (commonly used): file attribute hidden

File Attribute ReadOnly File Attribute System

The fourteenth findnextfile looks for the file.

Follow the FindFirstFile function for example!

If you are using the UNIX Linux operating system, you can use a powerful shell programming method to determine whether the current path is a word directory or a file; As for how to use powerful shell programming techniques to achieve your own goals, you must read the detailed documentation related to shell programming, as well as sed, awk, etc.

In a computer, a text identifier that points to a file or something that is pathed, usually with a slash.

or"/"Each interval is separated, with the slash followed by the previous child.

Represents the root path of the current path.

Eliminate envy represents the current path.
