Hello, i worked with Open Office program .docx extension file.

Now when i try to open same file comes this message (in attachment) ASCII Filter options . what is that?

Your file is corrupt, possibly because of your over-hasty power down of computer before hard disk had flushed its internal buffers to disk. There will be nothing usable in your file. See this
[[Tutorial] How to find and un-delete AOO temporary files
for details of how to recover temporary files, which may contain some or all of your data (or none).

If you saved many times there will be something to recover in a saved file somewhere. See the Tutorial Rory mentioned for full instructions to find what you saved. Follow the instructions for .odt files as AOO handles .docx files in the same way it handles .odt files.

See [Tutorial] Differences between Writer and MS Word files for why you should always work in and save files as .odt.
