As far as I can see (1) (2) (3) (4), the way JDK7 does it, is by calling GetFileInformationByHandle on the files and comparing dwVolumeSerialNumber, nFileIndexHigh and nFileIndexLow. Per MSDN: You can compare the VolumeSerialNumber and FileIndex members returned in the BY_HANDLE_FILE_INFORMATION structure to determine if two paths map to the same target; for example, … Read more
Take a look at FUSE: http://fuse.sourceforge.net/ This will allow you to write a filesystem without having to actually write a device driver. From there, I’d start with a single file. Basically create a file that’s (for example) 100MB in length, then write your routines to read and write from that file. Once you’re happy with … Read more
If you only need to check extensions (i.e. no further wildcards), why don’t you simply use basic string operations? for root, dirs, files in os.walk(directory): for filename in files: if filename.endswith((‘.jpg’, ‘.jpeg’, ‘.gif’, ‘.png’)): pass
You can do this with: git ls-files –deleted -z | xargs -0 git rm Whenever this question is asked, people suggest git add -u, but the problem with that answer is that it also stages other modifications in your working copy, not just deletions. That might be OK in many situations, but if you want … Read more
I’m not sure your list is quite correct. It depends on what you mean by a file system. If you mean a file system that is mountable in an operating system and usable by any application that reads and writes files using POSIX calls, then GridFS doesn’t really qualify. It is just how MongoDB stores … Read more
Does the .net framework has an async built-in library/assembly which allows to work with the file system Yes. There are async methods for working with the file system but not for the helper methods on the static File type. They are on FileStream. So, there’s no File.ReadAllBytesAsync but there’s FileStream.ReadAsync, etc. For example: byte[] result; … Read more

pyfakefs (homepage) does what you want – a fake filesystem; it’s third-party, though that party is Google. See How to replace file-access references for a module under test for discussion of use. For mocking, unittest.mock is the standard library for Python 3.3+ (PEP 0417); for earlier version see PyPI: mock (for Python 2.5+) (homepage). Terminology … Read more
