Hi it suddenly happened that a *.opj-file of approximately 2 MB increased in size to more than 47 MB. The total size of all objects in that *.opj did definitely not exceed 2 MB according to the size information of the Project Explorer.
I then deleted nearly evertything in the project-file and also in the code builder and saved the project file, but its size did not decrease.
What can I do to bring the size back to its real value again?
Open the script window and enter the command "list s" to get a list of all datasets in the project. There are probably many datasets that are not attached to worksheets that can be deleted.
