1. What is trycatch, when it is used, can this be used in all the workflows. Please explain.

Try catch is like
try what you want to automate and if it fails or sometime some error occurs means instead of failing the bot it will go to catch block where you have to take care what needs to be done once the bot fails
and yes you can have try catch for any number of workflow

hope this helps,

In simple terms, the try catch is used to handle exceptions/errors. If you need UiPath to do something other than throw an error, you would use a try catch to perform some action when the exception is thrown. A single activity can be placed inside the try catch or even an entire workflow. You can find more detailed information in this conversation:
