I am working with SolidWorks and external excel file but when saving stage appear this window and take too much time and finaly solidworks not response
I see you are using a linked design table, and that might cause some of the slow performance. Do you need to store the design table as a separate excel file? If you uncheck "Link to file" when you create the DT then it will save the table with the part file. You can still edit the table whenever you need to in excel by right clicking on it in the tree and choosing "open table in new window".
I am not sure why a linked DT would ever be necessary unless maybe other people who do not have SolidWorks need to update parameters and the design table is on a network drive or something.
That just made me think that you should check the design table file and make sure you have write access to it.
