Delete documents before strarting the routine

My Matlab script creates three different documents (.txt documents and .xlsx document). Every time I run the script I have to erase those documents manually in order to avoid problems. Does someone know a "script" which will go at the beginning of my routine that will delete such documents before running the analysis? Thanks.

Do tis for the wanted files:

if exist(FileName, 'file') == 2
  delete(FileName);
end

[Javier Martinez]

|Undefined function or variable 'FileName'.

Error in BAN_run_deGrib_hs (line 6) if exist(FileName, 'file') == 2|

It does not work

@Javier Martinez: it does not work because you never defined the variable FileName. To tell MATLAB what file you want to delete you have to define FileName.

@Javier: Define the variable "FileName" as the names of your files:

FileName = 'C:\Temp\File1.ext'

[Javier Martinez]

if exist(FileName, 'C:\Users\user\Desktop\TFM\Program\Datos.xlsx') == 2 delete(FileName); end

It still does not work.

I wrote:

You have exchanged the parameter 'file' of the exist() command instead. My instructions meant:

FileName = 'C:\Users\user\Desktop\TFM\Program\Datos.xlsx';
if exist(FileName, 'file') == 2
  delete(FileName);
end

It worked ! Nice thank you very much.
