In Desing file edited last week won't open.
Message: 'Cannot opent the file "......xxxx.....iddd". Adobe In Design may not suppoert the file format, a plug-in that supports the file format may be missing, ot the file may be open in onother application.'
I checked for updates – no help, all up to date.
Thank you so much in advance,
This message generally indicates one of two things: Either the file was not closed properly and there is still a .idlk file in the same folder (in which case open as a copy should work, or delete the .idlk file), or it isn't really an indesign file at all and it has the wrong file extension.
Or it’s corrupt.
