c# - Is there a faster way to copy a file other than File.Copy -


A takes approximately 2 minutes to file. Copy (src, dest); 1.6GB file to folder B from folder A to the same drive. To do this, C # /. There is a fast way in .NET code (W / O hardware) - something with the stream, threading etc.?

Will a movie get faster? How about a class that ends a file using a Threadpool, and reads a range of bytes / reads a range of bytes [which seems like a great way to corrupt the file, but Integrity is not a priority here, its speed :-)]

I searched but everyone uses the file. Copy, but it is slow (Slow as a copy of Windows) - I do not want to use any third party tool.

Here are some answers to some questions:

Comparison of time: 

  & gt; C #: 2.15m & gt; Windows Explorer: 2.53m & gt; Terracopy: 2.26m & gt; Fastcopy: 2.24m

OK, these are not average and I know they can change a bit in later run, but I really thought that a quick copy of the file The method would be because I had assumed that Windows was investigating additional security and integrity: - (

I'm still expecting some good answers (like 'oh yes, files over 1.5 GB < Em> x will be fast if you buffer m and turn off security n ') - OK, I just congratulate on this point.

The following Windows APIs may be helpful if you are interested in creating a symbolic or hardlink instead of an real copy.

    Eclipse CDT variable colors in editor -

    I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
