there's no info to determine what happened in the past.
you can check for an auto-recovery file*.
and in the future you should be saving your fla's periodically with an appended version number that increases with each save. eg, project1_v000.fla, project1_v001.fla etc
open AutoRecoverFilenames.txt** and see if there was a saved file and, if so, check the folder location listed
win: C:\Users\<username>\AppData\Local\Adobe\<animate version>\en_US\Configuration
mac: Users/<username>/Application Support/Adobe/<animate/flash version>/en_US/Configuration/
don't attach images:
in addition, to looking for a recovery file (and taking preventive steps in the future), you can try to repair your fla by renaming it to a rar > using winrar (or something comparable) repair the rar > rename the repaired rar to a fla > try to open the repaired fla in animate.
and you may be able to decompile a working swf (if there is one) into a fla using a decompiler (eg, sothink's)
Excuse me for the wrong attachment way.
So I must change .fla extension to . rar? and open it with ...?
Thank you very much
if you want to try repairing the fla, yes - rename and repair. that's probably going to fail but it sometimes works.
Yes, have failed.
Thank you anyway.
How can I repair? can't find any action like that ...
do you have winrar or something comparable (that can repair compressed files)?
No, I got nothing like that.
Mac OS Big Sur.
I really thank the link but as I indicated before I run Mac OS.
I see. But my file is not a zip file. it is a .fla file.
again, rename it.
