Electronic – Eagle project wont open, “Error reading file”

eagle

I'm working on a board layout with Eagle. I tried to open the file today and get a message "error reading file". No other info besides that and I haven't been able to find anything about this. It does this with both the .sch and .brd files. Any ideas?

If it is a recent Eagle version, you may open the .brd and .sch files with a text viewer, because they are basically xml text files. This may give you a clue of what is happening or a way to fix it.

BTW, eagle also keeps a few backups (exact number is configurable) of the last saves.

For example, .sch backups will look like this:

mysch.s#1
mysch.s#2
...

Similary, .brd backups will look like this:

mybrd.b#1
mybrd.b#2

And even library backups (previous saves) will look as follows:

mylbr.l#1
mylbr.l#2
...
