Not a diagram file (error on line 148 at column 878770: AttValue: ' expected)

[Oddeven]

This error always comes up whenever I try to open my drawio file.

I have used it for some time but one day this happened and I don't know why.

I do have a bunch of information there that I don't want to lose so I really need help to recover it.

[draw.io Q&A]

Hi,

It looks like the diagram was saved locally using desktop app.

If this is the case,  try to find two recovery files next to the main file (.$FILENAME.bkp and .$FILENAME.dtmp)  and check if you can restore the file or its previous version.

Also try right mouse click > Properties > Previous versions
