I am exporting a library (using the better biblatex format) and selected 'keep updated' so the file is maintained. But later I wanted to chang the name of the exported library, I made the same process with another name selected "keep updated and I deleted the old file. But if there is any changes zotero generates two files (old library name and new library name) with the same information, is there any way to stop zotero generating the file with the old name?
