During the development using Visual Studio, many time we faced that, there are so many open files in the editor. Sometime it is becoming very difficult to manage them, or to find a specific document or even navigate among them. As a next step we close all the documents and then try to open those specific document. Rather closing all document, you can first check all the list of open document and then close specific documents which are not required.
From the main menu navigate to Window –> Windows
The Windows dialog will list out all the open windows which are active as well as hide from the IDE View Port.
You can select any specific file to work on and Click on “Active” button, which will automatically close the “Windows” dialog window and keep the selected document open inside IDE.
To close specific documents, Select one more files from the list and then choose the option “Close Windows ( s ) “ to close them all.
Using this you can easily filter out and clean up which files are required most and which are not for that particular point of time.
Hope this helps !
