When clients upload files, they aren't required to add the year or month on their files. You may want to add or adjust these fields to assist with managing your files. Here's how you can do so efficiently.
To Edit the Year or Month of Multiple Files at the same time:
Select the Files page in the left-hand menu.
Select all of the files you wish to edit.
Scroll to the bottom and select the Tag icon → Add & Remove Tags.
Select the Year or Month radio button.
Select the desired Year or Month option.
Select Replace.
Note: you can only choose to edit one of the options at a time, meaning if you need to change the Year and Month, you first have to change the Year, then you can click on Add & Remove Tags to change the Month.
