I need to read just first 256 B from large file, from mapped WebDAV drive.
I open file with
h_second = CreateFileA(second_server, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, NULL);
but it first downloads whole file, and after that can I read it. And I want something, that downloads just a small part of file and I read that.
Can anyone help me?

To read from a text fileUse the ReadAllText method of the My. Computer. FileSystem object to read the contents of a text file into a string, supplying the path. The following example reads the contents of test.
Reading Large Text Files in Python We can use the file object as an iterator. The iterator will return each line one by one, which can be processed. This will not read the whole file into memory and it's suitable to read large files in Python.
To read large text files in Python, we can use the file object as an iterator to iterate over the file and perform the required task. Since the iterator just iterates over the entire file and does not require any additional data structure for data storage, the memory consumed is less comparatively.
WebDAV is an extension to HTTP, and HTTP already has a range request.
