Looking for help for my text document

[BlueWright]

Hello people,

I tried to open a somewhat important document today and was prompted with an ASCII Filter Option panel, which I never had before.
I selected multiple character sets but every one of them gave me similar bad results. The file in question is attached.
Can I recover my file somehow? I read something about a content.xml file.
Thanks in advance.

Your file is damaged and I doubt anything useable can be recovered from it. Your best hope of recovery is to try and undelete any temporary file OpenOffice was using. As soon as possible do the following:

Download Recuva or PhotoRec (only one needed) and let it do an indepth recovery of deleted files on your computer. You may get a file containing some or all of your data (or not). Do this as a first priority; other use of the computer may overwrite any existing but deleted files and prevent their recovery. There is no guarantee that you will recover anything useful.

Do this soonest - use of the computer runs risk of overwriting the deleted file(s).

The problem is that that file was saved on an USB-Stick.

The temporary files should be on the computer hard drive. The USB stick may have been removed too quickly - i.e., without proper observance of the USB device removal protocols.
