For that specific case, it is simple. After you have added some compressible data to the archive (plain text files or sprites are ideal - avoid compressed archives, GIF or JPEG images because they are already compressed), then count the contents of the archive, then count the archive size itself. Without compression, the archive size is a bit larger than the size of its contents. With compression, the archive size is substantially smaller. If you add large files you will notice the difference anyway - it is very fast for uncompressed archives and rather slow with "Deflate" compression. Finally, just to avoid misunderstandings: The compression type is *not* a property of the archive. There are no such things as "uncompressed Zip files" and "compressed Zip files". The file does not say anything about the compression to be applied. Each individual item in the file can be either compressed or uncompressed. The SparkFSMethod commands do not control the compression when creating an archive. Rather, they control the compression used when adding files to the archive. You can easily create a mixed archive: Create a Zip file (no matter what your current SparkFS settings are), then type *SparkFSMethod 4 0 and add a file. It is added without compression. Then, type *SparkFSMethod 4 8 and add a file. It is added with Deflate compression.
