I find the following to effectively explain folders in the Android email client :
The built-in Android email client is actually quite good. It may seem somewhat inflexible, but itís really only as inflexible as your email host. Let me explain. Take a look around the Android email client options. You will NOT find the ability to create folders anywhere. The Android email client can work with folders, but you must create those folders through your hosting provider. For example: I use Vervehosting for most of my personal/professional and client-based email. I can log onto the webmail client and create folders through a groupware tool (I primarily use Squirrelmail).
Theoretically, the folders created through Squirrelmail should show up when the Android email client syncs, but hereís the thing ó if youíve set that account up within Email as a POP account, those folders will not show up. In order to get those folders to appear, that account must be set up as either an IMAP or Exchange account.
Once the folders appear, you can move email around on the device to keep yourself organized. To move an email from the Inbox folder to another folder, simply select the email (or multiple emails), tap the folder icon (upper right, immediately left of the Trash icon ), and then select the target folder from the resulting pop up.
