directory_iterator is a LegacyInputIterator that iterates over the
directory_entry
elements of a directory (but does not visit the subdirectories). The iteration order is unspecified, except that each directory entry is visited only once. The special pathnames dot and dot-dot
If the directory_iterator
If a file or a directory is deleted or added to the directory tree after the directory iterator has been created, it is unspecified whether the change would be observed through the iterator.

Member functions
| constructs a directory iterator (public member function) |
|
(destructor) |
default destructor (public member function) |
| assigns contents (public member function) |
|
| accesses the pointed-to entry (public member function) |
|
| advances to the next entry (public member function) |
Non-member functions
| range-based for loop support (function) |
Additionally, operator== and operator!= are provided, either as members or as non-members, as required by LegacyInputIterator
Example
Run this code
#include <experimental/filesystem> #include <fstream> #include <iostream> namespace fs = std::experimental::filesystem; int main() { fs::create_directories("sandbox/a/b"); std::ofstream{"sandbox/file1.txt"}; std::ofstream{"sandbox/file2.txt"}; for (const fs::directory_entry& entry : fs::directory_iterator{"sandbox"}) std::cout << entry << '\n'; fs::remove_all("sandbox"); }
Possible output:
"sandbox/a" "sandbox/file1.txt" "sandbox/file2.txt"
