.odt text files?

[MSpagni]

Well, yes, in a sense .odt files are indeed text files.

Why EDP, by default and without any plugin, tries to compare them as "text" files?

[psguru]

Because they typically do not have enough "odd" characters to consider it binary using the EDPro heuristics.

[MSpagni]

Well, a bit surprising since those files are zipped, but your explication makes sense.

I'll put .odt in the "always treat these files as binary" list.
Thank you.
