text scan iterations

I have some files to process , but i have missing files in middle i am using

for i=1:file;

fid = fopen(['Raw',num2str(i),'.txt']);

D = textscan(fid1,'%*f %f%*f%*f%*f%f%f%[^\n]','delimiter',';', 'headerlines',50,'CollectOutput', 1);

fclose(fid);

Now the rest of program works well when i have files in order

i.e, 100,200 any number of files in my folder in order as Raw1.txt, Raw2.txt, Raw3.txt, ....

I get into trouble as soon as there are missing files like Raw1.txt, Raw4.txt, Raw5.txt

How do i iterate my text scan so it can ignore the file numbering?

Thanks

Edit :

By missing files i mostly mean numbers after 'Raw'

My files get generated as Raw1, Raw2, Raw3............ Raw400.txt

When all the files are in order and present i have no problem.

when i have some missing or jumps like for example Raw1 . Raw2.......... Raw10, Raw15, Raw16 I have trouble as there is jump from Raw10.txt to Raw15.txt I have same problem if my files start at anything other than Raw1.txt

look for exist in matlab documentation. Something like this should work:

for i=1:file;

    if exist(['Raw',num2str(i),'.txt'], 'file')
       % File exists!
       fid = fopen(['Raw',num2str(i),'.txt']);
       D = textscan(fid1,'%*f %f%*f%*f%*f%f%f%[^\n]','delimiter',';', 'headerlines',50,'CollectOutput', 1);
       fclose(fid);
    end

end

Note that exist(Name, 'file') checks for the file's directory too, so either give the full file name (i.e. with path), or try something like if exist(Name, 'file') == 2
