What do you lose whenever you...
Format /cache?
Format /system?
Format /data?
Can someone please go into detail about it? Thanks!

Dalvik compile results. Completely disposable. Will cause slower performance as the classes get recompiled the first time they're run.
Format /system?

The Android system apps and jarfiles (java libraries). If you do this, you'll need to reflash the ROM (like a nightly) and gapps.
Format /data?

All of YOUR stuff. Market apps, program configuration settings, etc. Larger datafiles will generally be in /emmc or /sdcard. Much of this will be backed up by Google if you enabled this and will trickle back, but it's a pain and some apps don't do it right or at all.
That said, any of these might solve some problem sometime. Clearing cache often fixes force-close problems due to stale or corrupted compilations. Clearing /system can clean out old versions of system stuff (I haven't seen this, and ISTR that the nightly install does this anyway; watch CWR while it's installing sometime). Clearing out data can fix rogue apps by deleting them completely, but erase their data and/or uninstall from Market first.
What's about /boot, stolen?
What harm if we format it?
And, just a little correction up there, format /cache alone doesn't perform wiping Dalvik

Then you can't boot from that device anymore. Reinstall.

Right, you need to clear /data/dalvik-cache, too, but that isn't needed with the usual updates, and it's harder to get to in CWR. But he didn't ask about either of those, or any other filesystems, and maybe you could fill him in?

I'm thinking about wiping my Nook since I can't get WiFisleep to work anymore. But what will happen to all my books and comics stored on the EMMC then? I'm running cyanogen 7 from the internal memory with no traces of BN(the first thing you get when you boot is a small cyanogen logo). Do I have to back all those files up?
If you wipe data and Dalvik you most likely lose those files (depending on where you have stored this files to save). I would suggest backing them up to your uSD to be safe for now.

Wiping Davlik will not delete those files. I wipe it every time I upgrade to a higher nightly. In fact, it is all that I wipe. The real question is will an update or reflash solve the problem? If it were me, I would flash an update using ROM Manager, wiping Davlik and including gaaps in the update. If that does not solve the issue I would then start from scratch since a system wipe will be needed. However, backing up the apps first using Titanium Backup (but not system settings) will get you back after the new flash.
pat is right, wipe Dalvik doesn't touch files but skeeter also right as wipe /data, everything most likely gone with the wind

Wiping /data will indeed wipe all downloaded applications and their associated settings but I think the OP is referring to media files stored on the emmc partition and this will not be touched by a data, system or cache wipe, just like SD card contents won't be touched.
I store some basic media files on internal emmc making use of about 4GB spare capacity. This gets scanned as well as the stuff stored on SD.
When the guide says full wipe it means deleteing system, data, cache and davlik cache right?
Do i need to format my emmc too? What happens if i format it? TIA~
What guide? What are you trying to do?
just trying to confirm whether full wipe means formatting system data cache and dalvik cache

Generally that's what it means. But if you wipe the first three you have wiped dalvik.
One of the reasons we asked what you were trying to do, you asked about wiping emmc too. It makes a difference what you are trying to wipe whether you try to do anything to emmc.
Edit: By emmc, did you mean the emmc media partition or emmc as the whole device? I can think of only one reason to wipe the emmc media partition, and that is if you are transferring the device to someone else and you want none of your stuff on there. I think a "factory reset" wipes everything except /system.

i meant formatting my /emmc
That is because i saw some traces of my photos thumbnails there even though i've moved the photos to my computer.

It won't hurt to erase everything in your media partition. Whatever the nook needs, it will rebuild. No need to format, just delete things with your file manager.

I have 500MB left and whenever I'm trying to update/install apps from the Play Story it gives me this error!
I tried clearing the dalvik-cache which is like 450MB but it force closes the whole system and apps!
After rebooting... the dalvik-cache is still there! I'm guessing that it's rewritten itself...
I think dalvik cache rewrites itself after it's wipe
That's Why it takes a long time to boot after dalvik wipe

Where do you have only 500mb left? Meaning /data/media or /cache (not /dalvik-cache).
Try going into Setting>Apps> Gallery, Playstore, video player, music player and wiping the Cache there. Gallery is a cache hog, so is Browser and Playstore.
Once you get that cleaned out, you should be able to download something from the market. I suggest Cache Cleaner NG. It is a cache cleaner that you can set to run everyday, week, month. I have mine set to run every morning before I wake up so my tablet is fresh and clean and ready to use.

happened to me before. reflashed and it fixed. should have use root explorer to check which directory is used.
So now I have 400MB on the internal storage and I've cleared all the cache!
What should I do next?
The error is still there!
I can't even install apps to clean my system!

Clearing cache from recovery is not the same. Go into those apps and wipe them there.
Also, take look in /data/log and see if anything is in there. I just read about someone yesterday that had 11gb of useless entries in there. If there is anything in that file, just delete it (it isn't needed) and the set the permission to User-R and the rest blank and you would get those files anymore.
If all else fails, just delete something from your internal that you can replace later on from your PC (like some music or video) and that way you'll clear out some space to download a cleaner from the market.

Yeah... I checked all the apps and cache was deleted!
There's no "log" at all!
Also why would I need to delete something from my internal?
I deleted a lot from downloads...
Your internal and /data/media are the same thing. If you said that your internal is almost full and you are getting the error,....

I know!
But I deleted a lot of stuff! and now I have 400MB!
400MB should be enough to install an 800KB app!
Just trying to troubleshoot here man. Use a file explorer and look around to see if anything sticks out.
Might be time to do a factory reset and clean house (as a last resort) unless someone else has any ideas.
Good luck.
You need to have at least 512MB on your internal memory to be able to instal more programs. There is no fix for that.

This might be the answer...
I've deleted a lot of stuff and apps and now I have 1.2GB an I installed couple of apps successfully!
He is correct, 512 is the limit, you will also notice the system slows ALOT after this point, I like to use my MicroSD for alot of things for this reason.
Also glad I read the 'log' tip, I had a 600Mb log just sitting there. X.x
I get this insufficient space error when titanium backup runs a scheduled backup. I have 18gb free and when I manually do a backup it works like a charm. Odd behavior. Sorry, I don't have any suggestions; just wanted to let you know you are not alone.

I do use a 16GB microSD BUT the problem is that I have 10GB of apps/games! -_-
Try Apps2SD or a similar app.
I know for sure that the huge amounts of resource files used by games like Shadowgun and GTAIII can be stored on the MicroSD, freeing alot.

Probably /data is on the verge of running out of available inodes, do you have a lot of small files on it?
Hello.
My question is clear, what will be deleted when I wipe system partition?
Also will the apps & their data will be deleted too?
Anything installed on the system partition. Basically, the entire OS.

But will this wipe delete other apps like Facebook & games...etc
Wiping /system removes Android from the device. Your apps and data are in /data, which is another partition. That is untouched unless you perform a factory reset.

Okay, thanks, that's what I want to know
Why? It's been stuck at 60.5mb used and 1.2GB free according to Diskinfo forever now. Ever since I restored Madvane's unrooted B180 backup & then flashed root with Magisk.
Why does it bother me? Because I have no idea what I'm talking about and I feel like maybe Cache is storing in the Data Partition where I install my apps...? Is it?
Also with 1.2GB free in the Cache parition & 1.2GB free in the System Partition, can I just partition those and make the Data partition bigger for more available Internal Storage for apps and stuff? I mean I have external storage as default location but so many files still get installed on internal and I'd like to expand that if I could alter these partitions.
Anybody done that before or can answer my questions? Thanks! Images attached
Anyone ?
I have not read of anyone here repartitioning internal storage. I don't think it's as simple as repartitioning a PC hard drive with a GUI tool.
Do you have any tools in mind to do this repartitioning? I think it would be a highly risky operation, so be sure to make full backups and note all the original settings of existing partitions before repartitioning.
You can Google threads on people repartitioning internal storage for other phones, but note the ones who ran into problems and bricked their phones.
I wouldn't mess with the partition sizes, personally.. in theory it works, but it can trigger some arcane safeguards added by oems.
Try wiping the cache partition in twrp..? Could have gotten bugged, which would throw an error and require reformatting
Is there any indication of a problem with the cache partition?
It's biggest usage would be to download an OTA file, so unless that's happening, I would expect cache partition to remain remain mostly empty as OP reported. Probably what's in there is TWRP or stock recovery logs - you can confirm with a root file manager.
Wiping the cache partition as suggested won't harm anything and it would be interesting to know what it's reported usage is after wipe and reboot.

I guess that was my question too. If there was any idication of an issue here. Seeing that free space I'd like to have it though.
On another note. There's no indication of anything being wrong with my Data partition but I formatted it to ext4 back when I bricked my phone in a hope it would fix something. But it seems fine. IDK what they default partition type was.
My data partition is ext4, which I believe is the stock default type.

Thanks man you've been allot of help. Have you tried L-Speed? I'm thinking about trying it. I do have Kernel Auditiur installed. Don't use it.
Nothing is broke but thought about trying L-Speed.
Never heard of it. If you try it, let us know what you think.

I just tried it seems like a nice and easy way to tweak performance or battery.
I prefer kernel adiuator myself.. L Speed has too many generic settings which do next to nothing for actual performance, reminiscent of the many garbage tweak programs that have been out there for years. K.A. allowed for better control of the cpu governor settings, which allowed me to negate some of the impact of emui's 'battery optimization'. A little bit of entropy tweaking on top of that, and I no longer experience nearly the amount of choppiness
