how to give spesefic name to fopen?

Hi everybody,

i want to to write a file with specific and every time (in for loop) different name?

For Example: i tried as following:

prjName='HafencityLabor';
ScanName='GComScan_20200217_124239';
ScanVolume='83964';
ScanFullName=strcat(ScanName, '_', ScanVolume, '_', prjName)
ScanF=fopen([ScanFullName  '.sdb'],'a+');

than i want to move the file into other subfolder as following:

outputFolder = fullfile(pwd, 'SDBsFiles');
if ~exist(outputFolder, 'dir')
  mkdir(outputFolder);
end
movefile([ScanFullName  '.sdb'], 'SDBsFiles');

but i get this Error:

Error using fopen
First input must be a file name or a file identifier. 

Thanks for your Helps!

The code in the first block works for me. Are you sure you have writing permission from the OS in that folder?

I can't seem to reproduce your error. It looks like your code creates a valid filename.

i'm sure i get always this Error!!

Since we can't reproduce your error, it is difficult to help to solve it.

Thank you guys for your Answer. i dont know what's the Problem. i solved it as folowing:

ScanF=fopen('scanname.sdb','a+');

newName=char(strcat(ScanFullName, '.sdb'));

movefile('scanname.sdb', newName)

movefile(newName, 'SDBsFiles');

it's not so cool but it works for me. ;)
