I have a serious problem with my latex file. I was working on my article, when suddenly all the work I made disappeared after running the document. I have to submit the article in one week. In the error line, only one error appeared:

File ended while scanning use of \textbf, but it didn't show in which line the problem is located.

Does someone know what to do and where can I find my work?

Thank you.

TeX never edits or changes your source file in any way, so any changes in your source (and any backups) are a feature of your editor (that you have not named).

The error means you have a missing }.

You should be able to detect the error from the log. There is no line number as the error is detected as the file ended, but for example










] [2])
Runaway argument?
{bbb \par ccc \par \end {document} 
! File ended while scanning use of \textbf .
<inserted text> 
<*> dd937

so here the [2] tells you it had just shipped out page 2 and then an argument starting bbb was never closed. From which you should be able to find \textbf{bbb fairly easily.

  • Thank you very much for your help!
