Moving forward, SharePoint should only be accessed using the browser, and should NOT be synced to file explorer - https://experience.k3techs.com/portal/en/kb/articles/how-to-access-sharepoint-online
WebDrive will map drive letters, but should only be used for certain tasks, covered below
PDF files should be opened using the “Open in Revu” Option in SharePoint- https://support.bluebeam.com/articles/revu-using-the-sharepoint-integration/
As mentioned in the above documents, pdfs can be Checked out from SharePoint to prevent other users from editing files while they are in use.
After the document is checked out, there are other options on how to save back to SharePoint - https://experience.k3techs.com/portal/en/kb/articles/checkout-documents-in-bluebeam-revu
Once connected to SharePoint, these files can be opened from the browser, either directly in the browser or in a separate instance of the desktop application - https://support.microsoft.com/en-us/office/open-a-onedrive-or-sharepoint-file-in-the-office-app-instead-of-the-browser-761c66d2-7bc3-490e-a536-b3f71f41636b
In order to lock the file for editing by another user, it needs to be checked out. Once editing is complete, it needs to be checked back in so that others can edit it. Note per the following document the proper sequence is:
Check out the document
Open the document
Edit the document
Save the document, or upload it
Check in the document
Office files opened in Word, Excel or Powerpoint will be automatically saved periodically because the Autosave function is turned on by default. Note this does not apply to files that are checked out
If you need to save the file under a new name, or a copy of the file, you can use the Save As function.
If you need to save the file as a pdf, you can do that - https://support.microsoft.com/en-us/office/save-or-convert-to-pdf-or-xps-in-office-desktop-apps-d85416c5-7d77-4fd6-a216-6f4bf7c7c110
If you need to print the file to pdf, you can point the file at the appropriate WebDrive mapped drive, and the pdf will get synced with SharePoint.
Microsoft Project Files should be opened from the SharePoint Browser - https://experience.k3techs.com/portal/en/kb/articles/how-to-open-project-files-from-sharepoint
There is no Autosave enabled on Project. You need to click on the save icon, or click on File -> Save to manually save the file when you are done editing
In order to rename the file or save a copy, you need to use the Save As function. Click on File -> Save As, and select the SharePoint location. It should be at the top of the recent section.
Currently MS Project does not support saving a file as a pdf, in order to convert a Project file to a pdf you need to print using a pdf printer, and then select the file location as one of the WebDrive drive letters.
The only and main purpose of WebDrive is to export PDFs from third-party applications to SharePoint document libraries. The SharePoint web interface should be used for all other functions.
The files associated with the adobe suite (Photoshop, InDesign, Illustrator, etc) can be directly open from and saved to the WebDrive mapped drives. Performance may be slow, as the files are still located in the cloud. WebDrive Cache settings may have to be optimized for performance.
WebDrive is just an alternate method of accessing SharePoint, so SharePoint/MS Office files that need to be attached to emails or uploaded to a website can be accessed from the WebDrive drive maps. You can drag and drop them, or navigate through the folders using the drive letters to more easily attach them to emails.
Bluebeam combine and organize functions can use the drives mapped by WebDrive, which will then sync the files with SharePoint
