I exactly meant what you said above in my question. Of course a file is not understandable by a software and it imports its info into its data structures. A software has a 1:1 relationship between its internal set of data structures and its native file format. But is it necessary that an alien file format be converted (filtered) to the current set of data structures in the software? Maybe or maybe not. If the software has only one set of data structures and only one system to process them then the external format must be converted. But if the software has 2 different systems for storing data in memory (RAM) and analyzing them then there can be no need for conversion, because the second system has a 1:1 relation with stored data in the file. I wanted to know which of these 2 possibilities is true for LO and found out that LO has only one set of data structures which goes 1:1 with .odt format but not with .doc format.

I asked this question because I wanted to know whether the process of doc -> odt -> odt' -> doc' is running under LO. Because in this case it's faster, more efficient and much more stable to work directly on .odt files, which reduces the redundant processes of conversion (filtering). 1.odt -> edit -> 2.odt is faster and much more stable than 1.doc -> internal DS of 1.odt -> edit -> internal DS of 2.odt -> 2.doc Regards, Sina Momken > > Nino > -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
