Is it possible to write a filesystem for Windows in pure usermode, or more specifically purely in managed code? I am thinking of something very similar to GMAILFS. Excluding what it is doing under the covers (GMAIL, Amazon, etc..) the main goal would be to provide a drive letter and support all of the basic file operations, and possibly ...
I don't know what they use in normal windows searching.But there is a technique in which you use indexing of files at once and then use the index later for faster searching.(e.g. Windows search 4.0) Is there any other way for faster searching than this? Can you elaborate from implementation point of view? (Assuming that I may need to im...

Hi, does anybody know of a secure 'read-once' local file access system? Or how one might create one? I realise that if data is to be used on a system, then it must be capable of being read, but I think it may be possible to severely limit how data is made available and reduce the possibility of it being copied and used elsewhere. These ...

I would like to develop a command line program that worked like so: myprogram /c [some_executable_here] Which launched the command specified by the user and "watched" the process (and any sub-processes) for read I/O and when that program exits, print a listing of files that were "read" (ultimately resulted in a read() system call). My...
I have a script running in the background that prints some output. I redirected the standard output to a file for log purposes. However I don't want this file to grow forever, what would be a good way to do rollover without coding the logic myself? (Either rollover based on date or file size). ...
While writing a Perl script, I got a requirement to write the user names with comma separation in only one line of the file. That's why I would like to know is there any restriction on the maximum size of the line in the .txt file. ...
I have a Cocoa application that stores a reference to multimedia files (images, videos, etc) on the user's computer. I'm wondering if there is a way to get a reference to that file other that using a file path so that if the user moves that file to a different folder on their computer, I would still know where it is. I'm currently stor...
I have some code that is reading a config file, but when I open the file in TextPad, I see different values than my application does. I checked it with Notepad. Notepad agrees with my application, TextPad shows something else. This is on Vista x64 Business. Any idea what could be causing this? I've looked in the Context Menu->Proper...

Hi, i'm developing a fuse filesystem that stores data in the RAM, but i'm having problems when i write something to a file. The file turns into a blank file. Here's the code: #define FUSE_USE_VERSION 26 #include <fuse/fuse.h> #include <string.h> #include <errno.h> #include <stdio.h> #include <stdlib.h> char hello_data[200] = {'h', 'e...
I want to keep a logfile, and I am using TextWriter/StreamWriter to write messages to my logfile. I call TextWriter.Flush() after writing the message, but my message still doesn't show up right away. It only shows up when I call Close, and I would rather not reopen and close the file all of the time just to see messages immediately. ...

I have this problem: I have a collection of small files that are about 2000 bytes large each (they are all the exact same size) and there are about ~100.000 of em which equals about 200 megabytes of space. I need to be able to, in real time, select a range in these files. Say file 1000 to 1100 (100 files total), read them and send them o...
Any programmatic techniques, portable or specific to NT and Linux that get the result of number of large files loading faster? I am after a 'ahead of time', a priori, whatever you prefer to call it mechanisms that I can control in code for two OS-es in question. Each file has to be processed in full, ie. completely in size and sequenti...
