Created attachment 110910 [details] that is the file I have problems with I was working on a file, I saved it and then, when I tried to open it, it is broken, all the text is gone, the only thing I can read is ####. It was a big work I was doing, how can I recover it?
You're file seems corrupted, it's only 1kb size. A docx is in fact a zip file with a specific structure.
The file is entirely zeroed (0x00, 1024 of them, which LibreOffice shows as 1024 '#'), and there is no information that can be recovered. I have not found any reports of people's documents getting turned into 1kb zeroed files, but I do find reports of (sometimes very angry) users having their documents turned into empty (0 byte) files. Short of using something like photorec, this may help recover the file: http://ask.libreoffice.org/en/question/6652/how-to-recover-former-version-of-document/ If possible, let us know which version of LibreOffice and Linux distribution was used, and more about what was in the document/why it was large (e.g. did you use images, charts, etc.).
added a better summary and set status to NEEDINFO
The file in question was .docx, so I assume this is for Writer, not Spreadsheet--a '#' for each byte is the result displayed in Writer; doing dd bs=1K count=4 < /dev/zero > test.docx libreoffice test.docx will cause the following appears in the command line: :1: parser error : Document is empty ^ and Writer displays an unformatted document with 4096 of '#'.
