Aspen保存的文件格式中apw文件和bkp文件的区别
bkp file explanation from Aspen:
Aspen Backup files contain a compact version of your Aspen Plus run. They occupy much less disk space than files saved in Document format, and are thus preferable for long-term storage.
Backup files contain all input specifications and simulation results, but no intermediate convergence information. If you reopen a converged run stored as a backup file and rerun the simulation, Aspen Plus:
· Reinitializes the streams and blocks
· Reconverges the entire simulation
Backup files are ASCII files. You can use them to transfer runs between:
· Computers
· Versions of Aspen Plus
The advantage of the Backup (.bkp) files over Document (.apw) files is that the Backup files are upwardly compatible through different versions of Aspen Plus and are portable. For example, they can easily be emailed. Backup files are binary files in a format that is compatible across versions. You can use them to transfer runs between:
Backup files can be opened and saved in Aspen Plus. They can also be imported into a current run, and partial or complete flowsheets can be exported. For more information, see Exporting Aspen Plus Files.
You can import runs saved in Backup format into your current run. Aspen Plus merges the information and specifications contained in the backup file with your current run.
For example, you can have two sections of a flowsheet stored in separate backup files. You can import these two backup files into a single run, merging the two flowsheet sections.
apw file explanation from Aspen:
Aspen document files contain all input specifications, simulation results, and intermediate convergence information. If you save a run as a Document file before you exit from Aspen Plus, the next time you open the run it is in exactly the same state as when you saved it. If you reopen a run saved as a Document file, Aspen Plus restarts the calculations using the previous results.
Document files can be opened in the Aspen Plus User Interface and saved.
Disadvantages
Document files (.apw) are larger than other ways of saving a simulation.
Document files from Aspen Plus 12.1 and earlier are not compatible across different versions of Aspen Plus. Newer document files contain an embedded .bkp file which can be read by later versions of Aspen Plus. If necessary, this backup file can be extracted using the backup file utility apstgutl.
Advantages
For longer simulations, Document files are much quicker to load into and save from the Aspen Plus User Interface.
Because Document files contain intermediate convergence information, the run can be started exactly where it was saved. Intermediate results are especially useful when you save a file while in the process of trying to converge a large flowsheet.
For BKP file, You can open the new version file in old version program . before that you need change the version data in BKP to your version number, forexample: Aspen 2006.5 is 21, Aspen 2006 is 20, in the bkp file change 21 to 20, then it can be openned.

2.*.apw文件格式是以二进制格式保存的，包含所有输入、模拟结果和中间收敛信息，版本之间不能直接打开；
3.*.apwz文件格式是综合文件，以二进制格式存储，包含模拟过程中的所有信息，占得空间大。 谢谢楼主的分享
