@Sophie: "I have 70 files looped in to my script" - while this is surely clear to you, because you see the code in front of you, the readers have to guess, what this means. How can a "file" be "looped"? Post your code to allow to suggest a modification of it.

If you are using F=dir('*.nc') (.nc is the file extension or it can be any file extension) to read all 70 files, then you can simply use
F([9,15,21,30,35,60])=[]

No. F(9,15,21,30,35,60) would access a 6 dimensional array. Maybe you mean:
F([9,15,21,30,35,60]) = [];

What do you have about them? Their filename? If so, you can just ismember() to see if the current filename is one of the ones to be excluded, then continue. Something like (untested)
dirList = dir('*.png');
for k = 1 : numberOfFiles
thisFilename = fullfile(dirList(k).folder, dirList.filename);
if any(ismember(thisFilename, filesToBeSkipped))
continue; % Skip this one
end
% Continue with code for files you want to process.
end

@Image Analyst if I use your suggestion, for some reason nothing happens ('time.xlsx' - file I dont want to read). Do you know the reason? How can I fix this type of error, when nothing is printing and I dont understand why?
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
if any(ismember(baseFileName, 'time.xlsx'))
continue; % Skip this one
end
fprintf(1, 'Now reading %s\n', fullFileName)
end

Because you did not give a list. You gave a single string. To skip that one particular file, you can do
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
if strcmpi(baseFileName, 'time.xlsx')
continue; % Skip this one
end
fprintf(1, 'Now reading %s\n', fullFileName)
end
