Server Version#:1.43.1.10611
Plex Media Server on Windows 11 leaves index-sd.bif.tmp files next to completed index-sd.bif files.. Logs show “The process cannot access the file because it is being used by another process.”.
ProcMon filtered to index-sd.bif.tmp shows only Plex Media Server.exe;. The failing operation is CreateFile,
Desired Access: Read Attributes, Delete, Synchronize.
ShareMode: Read, Write, Delete.
Result: SHARING VIOLATION.
As a result, enabling video preview thumbnails uses double the space than it’s supposed to. Tested on newly installed Windows 11, and Plex. Reinstalled Plex from scratch with same result. Only workaround is to delete the index-sd.bif.tmp files manually or with a script
