Hello Claus,<br>
<br>
You can use "isfile" function to check existence if a file and
"isdir" for folder.<br>

<div>Dear Scilabers</div>
<div><br>
</div>
<div>I wish to check for the existence of some files. For this I
created a simple function:</div>

</div>
<div><br>
</div>
<div>I didn't check, but presumably this would work.</div>
<div><br>
</div>
<div>Is such a function already available? Which way is the
"official" way to do this in Scilab?</div>
<div><br>
</div>
<div>Maybe I'm searching for the wrong word, but I found some
ways in Scilab. The "fileinfo" seems to be the closest one to
what I wish to do.</div>
<div><br>
</div>
<div>Matlab has a function "exist()" which can check for files
too. Scilab has the function "exists()" - notice the function
name is plural, not singluar - and this one AFAIK only works
for Scilab variables (not files), although I didn't check.</div>
<div><br>
</div>
<div>If fileinfo is the right way, maybe an example for the help
could be to make a file_exist function, to show ... (?)
... when I search for Scilab file exist function, I'm not
guided in any specific way/direction and find myself insecure
whether I find the right help.</div>
<div><br>
</div>
<div>Best regards,</div>
<div>Claus<br>
