I have Lubuntu and I write document with libreoffice (188.8.131.52) during the last 2 weeks, the file size was around 100-130 kB.
During this time I saves this document and shutdown my pc few time.
Today, when I tried to open this document, I saw the file size is 9 kB, and I got error
Some errors were encountered during the import.
How can I recover my document?
