Working with documents online has its advantages. You don't need to constantly update the file versions. You can work on a document simultaneously with other people. Also, you don't need any additional software - all the work can be done in your browser.
In Bitrix24, you can use Google Docs for working with documents. Go to the Bitrix24.Drive section > click the cogwheel button > Settings for working with documents.
Click In the cloud > Save.
Open a document you want to edit > select Google Docs > click Edit.
Allow Bitrix24 Connector to access your Google Account.
Now you can edit the document together with your colleagues.
Once you've finished, don't forget to click Save after closing the window.
