Python 3’s pathlib module makes this straightforward with its Path.parents attribute. For example: from pathlib import Path root = Path(‘/path/to/root’) child = root / ‘some”https://stackoverflow.com/”child”https://stackoverflow.com/”dir’ other = Path(‘/some/other/path’) Then: >>> root in child.parents True >>> other in child.parents False

So, the following code should work fine: String.Compare( Path.GetFullPath(path1).TrimEnd(‘\\’), Path.GetFullPath(path2).TrimEnd(‘\\’), StringComparison.InvariantCultureIgnoreCase) Or, if you want to start with DirectoryInfo: String.Compare( dirinfo1.FullName.TrimEnd(‘\\’), dirinfo2.FullName.TrimEnd(‘\\’), StringComparison.InvariantCultureIgnoreCase)
External fragmentation Total memory space is enough to satisfy a request or to reside a process in it, but it is not contiguous so it can not be used. Internal fragmentation Memory block assigned to process is bigger. Some portion of memory is left unused as it can not be used by another process.

This doesn’t give the name of the partition, but you can get the filesystem statistics directly using the statvfs Unix system call. To call it from Python, use os.statvfs(‘/home/foo/bar/baz’). The relevant fields in the result, according to POSIX: unsigned long f_frsize Fundamental file system block size. fsblkcnt_t f_blocks Total number of blocks on file system … Read more
There are several ways to do this depending on the platform.
