Default Cleaning up crap files before flashing a ROM

I've been flashing a few roms lately, and I seem to be running low on internal SD storage. When I look at my file system, there is a lot of junk in there that I don't recognize. Some of it is obviously from apps that were in use on a previous ROM, but some of it I am not sure what it is.

I really just want to be able to flash roms or restore some recovery backups (I'm using OUDhs CWM 1.0.3.3, so it is keeping the recovery files at /sdcard/clockworkmod/backup/). Everything else, I am happy to nuke from orbit.

So, what dirs do I minimally need? What steps do I have to follow to do this? What is the difference between "factory reset" vs "cache partition" vs "dalvik cache"?

Factory reset wipes the data partition.
if you wanna delete internal sd card you would choose format/internal sd.
but remember to pull out the folders you want.

Thanks for the quick response.

So I guess I am trying to figure out what folders I want. If I want to recover my old recovery backups, can I do that after doing a factory reset? Or after formatting the internal SD?

recovery backups are in the twrp folder.

Thanks again for the response, xXchrizhurtyXx. Though I am not exactly sure how that answers my question. I'm kinda a noob to this world, so you'll have to excuse my lack of knowledge on these sorts of details. Is that folder effected by a factory reset? I presume it is by formatting internal storage, but correct me if I am wrong. Does OUDhs need anything besides that dir to restore a backup?

Also, diverting slightly away from my original question: When I boot into the recovery console, OUDhs reports that the recovery data is in /sdcard/clockworkmod/backup/. I can't seem to find a "twrp" dir anywhere on my phone.
