To upload a new version of a file into Procore's Documents tab.
Go to the Company or Project level Documents tab.
Using the file tree on the left, select the file you would like to upload a new version of.
In the file overview window, click Choose File under 'Upload a New Version". ( Note : It is recommended that you first check the file out to prevent people from downloading the old version while you're uploading the new version.)
Select the file you wish to upload.
The new version will now appear on the version log.
