Algorithm for determining a file's identity

For an open source project I have I am writing an abstraction layer on top of the filesystem. This layer allows me to attach metadata and relationships to each file. I would like the layer to handle file renames gracefully and maintain the metadata if a file is renamed / moved or copied. To do this I will need a mechanism for calcu...

virtual file? in c/c++ or C#

What I would like to do is modify all the files in a directory so they use a standard encryption, requiring a password and a 2nd layer of my own encryption. I would like have my application look at the directory and make a virtual, decrypted directory to open these files as normal. They requires non linear reads (i.e. audio file that I m...

Access a large file in a zip archive with HTML in a python-webkit WebView without extracting

I apologize for any confusion from the question title. It's kind of a complex situation with components that are new to me so I'm unsure of how to describe it succinctly.

My intention with the library is to provide natural means of accessing the resources of the games I develop, which store some data embedded in the executable, some on the media and some on the local user's har...

`virtual' files

Sometimes I'm downloading big files which have been split into chunks, say, a 1GByte file into ten chunks with 100MByte each.  Currently, I have to concatenate all files into a new file to be able to access it as a whole.  I now wonder whether it is possible to group these chunks into a virtual file (similar to virtual file systems), avo...

Ruby generic filesystem libraries

I am looking for a "Virtual File System" type library for ruby. I want to be able to have a completely generic file system that I can easily switch between using Local files and using S3 or using FTP or something like that. (Identical to VFS for Java) Has anybody used any type of generic file system for ruby (I just need it to support l...
