Here’s a procedure I have worked out for loading songs in bulk.
After lots of scanning of music books I obtained Kingsway’s Digital Songbook (600 pdf’s of music in Songs of Fellowship and 75 others) to speed things up.
I have Windows Explorer open as well as PM3 to directly access the pdf’s. In Explorer, with the cursor on the pdf file to be loaded into PM3, I use F2 function key to go into file rename then Cntrl C to copy the name to the Windows clipboard.
To avoid picking up the file name extension as well, in Windows Explorer, go to Tools / Folder Options / View and select “Hide extensions for known file types”.
In PM3, once you have located the drive and folder holding the pdf’s, you can paste the file name in to Sheet Music/open pdf filename box.
The file name remains on the clipboard so you can also use it for a song name in the Enter Title box when adding a title.
Once I have created a new song I switch back to Explorer to pick up the next file name but before doing so, drag the file just used to a “Done” subfolder to avoid having to select from a list every time.
Saves a lot of text input!
