Hi,
I'm using save() to save a workspace variable on a network share. Sometimes, the share is temporarily unavailable. How can I instruct save to give up trying to save the file after a specified timeout?
Thanks!

It is best to avoid this situation. Save locally if you can, and then once the data is written, copy it to the network share. This will also be faster.

That's what I'm doing, but even when just copying data, I don't want to wait for the pre-set timeout if the share isn't available. It takes minutes until save() throws an error, although from experience, I know that the share is unavailable unless the save command works ~immediately.

Avoid doing the save() to a share. save() locally. copyfile() afterwards.
Is there a way at the Windows command level to tell if the share is available?

What is the advantage of copyfile() over save() with respect to gracefull handling disk access problems?

Try to open a file on the drive first, if you can't open it, then the drive is unavailable. Overall, Walter's approach is better and more stable, though and I would recommend following it.
fid = fopen(fullfile(thedrectory,'Arandomfile.txt'),'w');
if fid == -1
error('Couldn''t open')
end
