If you don't compact folders your mail folders can grow very large and the program can behave erratically, so it's a good idea to do it periodically. Don't confuse compacting folders with compressing files. It isn't some unique feature of Thunderbird.
To get to the setting, click on "Options" in the [≡] menu. In the Advanced → Network & Disk Space tab, uncheck "Compact all folders" and it won't bother you again for an automatic compact.
The Account Settings window will appear.Click the small "plus sign" to the left of the account to expand the list beneath it. Click Server Settings. Check the box next to Leave messages on server. You may also want to check the Until I delete or move them from Inbox option as well.
The cache is basically exactly the same as the browser cache. Thunderbird can display RSS feeds, which are basically web sites. Web content can be cached. Letting CCleaner mess with files in the Thunderbird profile usually is a bad idea. If you feel you need to clean the cache, do that via Thunderbird Options.
In Thunderbird, right-click the folder and choose "Properties". Under "General Information" tab, click the "Repair Folder". In Thunderbird, right-click the folder and choose "Properties". Under "General Information" tab, click the "Repair Folder".
When you compact, all of your permanently deleted email gets deleted for real. The files are rewritten so they only contain the mail that you actually have. As a result, the mail has a smaller file size and it becomes slightly faster to access because the messages are closer together.

A Thunderbird local storage folder works just like an IMAP folder, with one important difference. All local folders are stored on your PC. This means that rather than filling up your valuable / limited storage space on the email server, you are using the storage capacity of your computer's “local” hard drive.
By default, email on Thunderbird is stored on the server side. However, it is possible to open a "local archive" and move your mails in this archive in order to store them only on your local machine.
