Hey,
i have multiple folders, within every folder is a .txt file. I need to run a script on every .txt file independently and need the output in the same folder as the .txt file is.

The MATLAB approach:
P = 'absolute or relative path to where the subfolders are';
S = dir(fullfile(P,'*','*.txt'));
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
% your code here, to process file F
output = ..
G = fullfile(S(k).folder,'output.txt')
% save output data in file G
end

With many assumptions, e.g. that the required folders are all subfolders of one parent folder.
You should also pay attention to the advice you got for your prior questions, e.g.:
opts = delimitedTextImportOptions("NumVariables", 9, "Encoding", "UTF16-LE");
% Specify range and delimiter
opts.DataLines = [30, Inf];
opts.Delimiter = "\t";
% Specify column names and types
opts.VariableNames = ["Name", "Frequenz", "Var3", "Var4", "Var5", "Var6", "Var7", "Var8", "Var9"];
opts.SelectedVariableNames = ["Name", "Frequenz"];
opts.VariableTypes = ["double", "double", "string", "string", "string", "string", "string", "string", "string"];
% Specify file level properties
opts.ExtraColumnsRule = "ignore";
opts.EmptyLineRule = "read";
% Specify variable properties
opts = setvaropts(opts, ["Var3", "Var4", "Var5", "Var6", "Var7", "Var8", "Var9"], "WhitespaceRule", "preserve");
opts = setvaropts(opts, ["Var3", "Var4", "Var5", "Var6", "Var7", "Var8", "Var9"], "EmptyFieldRule", "auto");
P = '\\DEDOSAN001\vol1\E\EMV\Kularia\Matlabprogramm\04_Messungen';
S = dir(fullfile(P,'*','Ergebnistabelle.txt'));
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
T = readtable(F, opts);
G = fullfile(S(k).folder,'RA1_AV.asc')
fid = fopen(G,'wt');
fprintf(fid, '%3.4f\t%f\n', [T.Name,T.Frequenz].');
fclose(fid);
end
