Looked at a few of the posts here but couldn't figure out the regexp... Could someone please help?
current file name: "A-001 - General Notes Symbols Abbreviations.pdf-M-0-0-A-001 - General Notes Symbols Abbreviations" (the extension is pdf).
needed file name : "A-001-GeneralNotesSymbolsAbbreviations"
requirements (1) find and remove from ".pdf" to the right (2) remove all spaces, (3) ignore file extension.
