Labels: Charset FLA export Old FLA formats

State: upgraded Help

> What steps will reproduce the problem? I loaded a SWF file and exported it in Flash 5 and MX FLA format. I attempted to open the output FLAs in Macromedia Flash 5, MX, and Adobe CS6. > What is the expected output? What do you see instead? Expected for documents to load. They all gave the same error, "Unexpected File Format" across the three versions of Flash tested. They could not be opened. > What version of the product are you using? Is it "nightly build"? Which operating system do you have? v.22.0.2, installed from DEB package on GitHub. > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. I tried a few files, one is attached in both Flash 5 and MX formats. Thank you!

This should be better in nightly 3038, try it. For SWF files with version 5 and lower, it is recommended to set its charset (defaults to WINDOWS-1252). You can set it with right click on SWF node / Change charset. For this file, WINDOWS-1252 is okay, for other files (especially chinese, etc), other charset setting should be selected.
