It is strongly suggested here that you attach your files to your post, and not on some external server. Most members here are reluctant to downloading files from external servers, specially if you forgot to mention the weigh of the file.

Attachment's size is 300kbs max. If your .fla is too big to attach, it's likely that the images in its library are too heavy. Since this Forum is all about Actionscript, having images in the .fla is really not necessary. What you can do is:

1 - Make a copy of your .fla
2 - Open the library (control-L) and delete all the images. They will be replaced in the .fla by red shapes - which weigh nothing. Your file should be ok to attach now.

Thanks for your cooperation.
