Hi to all,
I have a swf file whose fla file has been deleted unknowingly.So is there any solution to get fla file from that file ???

Not really, once the fla has been rendered to swf the file is flatted, you can however extract some resources such as sprites, your action script and images.

A good tool to use would be flashtoolset.

There r lot of decompilers which can extract fla file from swf file.There is Deflash - SWF Decompiler which can extract all resources from swf file and store them directly to ur hard drive.With use of this software You can easily get fla file.

I use Sothink SWF Decompiler. If you cant find / download it, if you want to you can send me the .swf file and I will decompile it and send it back to you as a .fla

Here's a decompiler in case someone may need it. You never know. Free to download in zip format.
