### Problem opening .lyx file

Hi everyone,

I am using Lyx 1.6.7. I saved an important .lyx file on my memory stick, and I cannot open it in Lyx anymore. I get the following error information:

Error returned from iconvEINVAL An incomplete multibyte sequence has been encountered in the input.When converting from UTF-8 to UCS-4LE.Input: 0x61 0x64 0x62 0x64 0xcbError returned from iconvEILSEQ An invalid multibyte sequence has been encountered in the input.When converting from UTF-8 to UCS-4LE.Input: 0xca 0x42 0x65 0x63 0x60 0x68 0x4f 0x6cCompleted

I can open the file in notepad and see my text. Now I could copy the text into a new lyx file and redo the many formulas. But given the amount of formulas in the document, I would like to open it in lyx.

This file is a child document in another document. The 'mother' file has the same error. Perhaps this has something to do with it.

Does anyone know how to recover the file?

Regards,
David

For starters, make sure that you don't have and non-ascii characters in the path to the .lyx file (as well as in the name of the .lyx file itself). Characters like ê, à, č, đ etc. in the path often cause problems, and not only with LyX.

If this isn't the problem, try using LyX 1.6.8 to open the file.

I found out the problem. Lyx made an error while writing the file away last time, and forgot to put
\end_body\end_document

at the end of the document, so LyX just kept on going. It also deleted some of my text. Luckily a .lyx~ file with the complete correct code was also in the folder, so I copied this code to the .lyx file and all is well now What is that .lyx~ anyway?

.lyx~ is a backup file which is produced by default automatically every 5 minutes and when saving your file (Tools > Preference > User Interface > Documents). These files are invisible on Linux, but I'm not sure about Windows.

Thanks! Wish I had known this before I despaired of recovering my document.

Yes, .lyx~ is visible in windows.
