calc I'm using "Calc Spreadsheet in LibreOffice 4.3"

bwb30815 I need to recover file (69729.pdf ((this file not on my computer)) how do I work around this file and how can I get past. So I can open file I need to open. Been trying to recover but keep getting error LibreOffice 4.3 (Not Responding).

Sorry but I feel there is more information and clarification needed. ---- If file “69729.pdf” is not on your computer, where is this file stored? — How was this file created? — What kind of file (= what is the extension of the file) are you trying to open in LibO? — What exactly did you do to recover your file? — Please have a look at What information should I include in a question in addition to OS and LibreOffice version? - #4 by ROSt53
