s in my documents folder. File name: .~lock.Manila Hotels.odt#
This is a "lock" file; it is housekeeping to prevent a second instance of OpenOffice trying to edit the file. If OpenOffice is closed, this file should be erased automatically. If it is not, then your OpenOffice terminated abnormally (crashed). This, and all other lock files, can safely be deleted when OpenOffice is closed. However, to ensure that you do not delete the main files, check that these lock files have a size of about 80 bytes before you delete them. Then look for your file, which is called Manila Hotels.odt, and open it.
Apache OpenOffice 4.1.3 on Xubuntu 16.04 (mostly 64 bit version) and infrequently on Win2K/XP
