| static CreateDirectory_(const String&) | Creates all directories in the specified path if those don’t exist. |
| static Delete(const String&, bool) | Removes the specified file or directory. Does not throw. |
| static EnumerateDirectories(const String&, const String&, SearchOption) | Searches for the directories that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static EnumerateFiles(const String&, const String&, SearchOption) | Searches for the files that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static EnumerateFileSystemEntries(const String&, const String&, SearchOption) | Searches for the files and directories that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static Exists(const String&) | Determines if the specified path refers to existing directory. |
| static GetCreationTime(const String&) | Returns the creation time of the specified entity as local time. |
| static GetCreationTimeUtc(const String&) | Returns the creation time of the specified entity as UTC time. |
| static GetCurrentDirectory() | Returns the full name (including path) of the current directory. |
| static GetDirectories(const String&, const String&, SearchOption) | Searches for the directories that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static GetDirectoryRoot(const String&) | Returns the root directory of the specified path. |
| static GetFiles(const String&, const String&, SearchOption) | Searches for the files that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static GetFileSystemEntries(const String&, const String&, SearchOption) | Searches for the files and directories that satisfy the specified search criteria either in the specified directory or in the whole directory tree rooted in the specified directory. |
| static GetLastAccessTime(const String&) | Returns the last access time of the specified entity as local time. |
| static GetLastAccessTimeUtc(const String&) | Returns the last access time of the specified entity as UTC time. |
| static GetLastWriteTime(const String&) | Returns the last write time of the specified entity as local time. |
| static GetLastWriteTimeUtc(const String&) | Returns the last write time of the specified entity as UTC time. |
| static GetLogicalDrives() | NOT IMPLEMENTED. |
| static GetParent(const String&) | Returns a shared pointer to DirectoryInfo object representing the parent directory of the specified entity. |
| static Move(const String&, const String&) | Moves the specified entity to the new location. If the entity to move is a directory, it is moved with all its content. |
| static SetCreationTime(const String&, DateTime) | Sets the creation time of the specified entity as local time. |
| static SetCreationTimeUtc(const String&, DateTime) | Sets the creation time of the specified entity as UTC time. |
