sharing .blend

this may be a newb question but how to i package a file to share on here for help? i tried before and none of my textures or anything went with so the question i had in particular was confusing as it was about the textures. this would also be helpful for posting on things like turbosquid or blendswap. as ive also had issues with getting peoples textures they have packaged with the object on blend swap

For textures, at least, you can go to File > External Data > Pack All into .blend

Instructions linked in my signature.

thanks that helps alot
