You can't "append to the middle of it". Appending by definition means adding on the end. You can overwrite the middle, but it's not going to push everything up to make room (i.e. filesystems don't work like text editors where you can 'insert' stuff just anywhere). The only way this would be relevant to extent allocation is in the case of sparse files, where the file has a certain logical size but a lower physical size. If you don't know what I mean by that, kindly read up on sparse files before proceeding. poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
