I am using Welcome to Adobe® Flash® Builder™ 4.6.
I don't want those flex things appears at the content assist classes list, I didn't use them at all. it's pretty meaningless. those classes seems appear at anywhere whether the project include them or not.
then I did a check at the lib path and did some experiments but I don't know if I delete too over the top I will get into trouble in the future. for I don't know the exactly usage of each swc package.by far i only know playerglobal.swc can't be removed, or the compiler won't work.
if you know the details of those package, please tell me, so I can decide which files i can remove
