I use a separate folder on the tablet's SDcard that contains just the fakebooks and their CSVs. I copy directly from the PC to the tablet using TotalCommander for Android with its extension TotalCmd-LAN. This uses only my local WLAN, no internet connection is required. The folder on the PC has to be shared (SMB).

That makes it more organized, I guess. So am I right in saying that you don't use the MobileSheetsPro Companion to transfer your PDFs, but instead use the Import feature from the app itself?

I ought to try this. Thanks!
