How to deal with .001, .002 … files

It could be .iso.001, .iso.002 … or .part1.rar, .part2.rar … or .r01, .r02 … etc etc.

There’re two possibilities to extract these files. 1. These are slpitted files during compression using winrar. Put all files in one folder. Just extract the first file, it will extract everything. 2. These are splitted files using splitting software such as cutncopy, hjsplit etc. We need use them to joint all files together.

There’re some explaination links:


Show hidden files and folders


I got a problem with my computer. I can’t show hidden files and folders. If I choose “Show Hidden Files and Folders”, it will be change back to “Do Not …” . I did a search on the Net. The second solution solved my problem.

Solution 1:

  1. Start->Run->Regedit
  2. Go to:


  1. Set key Hidden = 1
  2. Refresh

Solution 2:

If you got RavMon virus etc, you may need this.

  1. Start->Run->Regedit
  2. Go to:


  3. SET DWORD key CheckedValue = 1If it’s not DWORD value, delete it and recreate as DWORD value and set it to 1.
  4. Refresh


Foxit PDF Reader/Editor

Acrobat is very powerful. But the it’s pretty big taking a lot of space and memory. With version 8+ professional, people can create fillable and savable forms. For those files with un-savable forms, people can only print it after they fill out the form which sometimes make things annoying. Most of times, we just use it to read and print papers stuff. When we are viewing a website with a pdf file and we want to open it. Then we need a while to wait for the acrobat to bootup. For some computers, it could cause problems if the file is pretty big or you have a lot of files to open.

I started using foxit reader/editor a while ago. It seems this is a pretty nice alternative. It’s very tiny small which takes a little harddrive space and memory which of course will also vary for different sized pdf files. And, it could even edit any file and SAVE it even no matter if it’s a fillable or savable form. So I would use foxit as my main pdf reader. If necessary, e.g. I want to do some advanced work that foxit can’t do, I run acrobat. Actually, there are a lot of advanced add-on features with foxit that we could download anytime. But those are not free. The foxit editor can basically create a pdf file like using word. If you could get a cracked editor, you can use it without any marks printed on your file.

“include” a .m file into another .m file

If you’re trying to call the main function of another file inside your first
file, just call it like any other MATLAB function.
If you’re trying to call a subfunction in the second file from within your
first file, you can have the main function in the second file be a
“switchyard” that accepts the name of the subfunction to call:

% begin switchyard.m
function y = switchyard(fcn, x)
% Call as:
% y = switchyard(‘mycos’, 1:10);
% or
% y = switchyard(‘mysin’, pi);

y = feval(fcn, x);

function y = mycos(x)
y = cos(x);
function y= mysin(x)
y = sin(x);
% end switchyard.m

or you can have the main function return a handle to the subfunction and
call them that way:

% begin createhandles.m
function s = createhandles
% Call as:
% s = createhandles
% y1 = s.mycos(1:10);
% y2 = s.mysin(pi);

s.mycos = @mycos;
s.mysin = @mysin;

function y = mycos(x)
y = cos(x);
function y= mysin(x)
y = sin(x);
% end createhandles.m

If the other file is a script, just run it by typing the name of the script.
