xlswrite and Prompt for file save

I'm using xlswrite to save data to a file that I create the name for. Often the xlswrite command will open a "Save As" dialog with a different file name consisting of 8 alphanumeric characters. I can't figure out why this is happening. Anyone else experience this?

I experience same too. Once you save the file, you have an error in matlab "Error using xlswrite (line 219) Error: The server threw an exception". Don't know what the issue is

So, Dee, do you first get the error and then it somehow continues and asks you to "Save as", or does it ask you to "Save as" first, and then you get the error? Where did you try to save it to and what operating system are you using?

8+3 filenames would be "short names" for compatibility with older MS Windows. On NTFS file systems, every file has an 8.3 equivalent name.
