You can now open .XAR files in Scribus 1.6 Open Source Page Layout software

[Michael]

Confirmed. Scribus is able to open and render .xar files. Even complex ones

But ...

A quick test showed the following results: most of the items are locked. All layers are imported. Text is imported as shapes. Some weird artifacts all over the place. Pages are overlapping

Used xara file from v19. Imported in Scribus 1.6

no surprise; opening the file is the easy bit; making sense of it requires knowlege of how the program actually works internally
