Rooted nexus 4: file structure - Nexus 4 Q&A, Help & Troubleshooting

I'm new to android, I apologise in advance if this is a stupid question:
I rooted my Nexus 4 and was browsing the memory using astro file manager. I don't quite understand the file structure on my phone as to what files are safe to fiddle with and what are not.
For example there are three folders with exactly the same content: storage/emulated, storage/sdcard0, sd card. Why?
Am I right thinking all the folders under the root (home) directory should be left alone? But ones in the above three directory can be deleted? They seems to contain app data.
I want to clean up my phone memory so that's why I'm looking for files to delete.
Thanks everyone

Folder Structures in SDCARD

Hi everybody!
I just got my DHD and already root, clockwork, changed rom, etc. However, my problem is related to the directories structures inside my SDCARD.
I have 2 questions:
1- I moved some apps that I have in my main memory to my SDCARD via App Settings. However, when I go to my sdcard in windows explorer, I don't find these files. I'm not sure then if is really moving to my sdcard. I just realized some new folders, but they are empty. Does anyone knows what I'm doing wrong?
2- The second question it's linked with the first. I would like to organize in my SDCARD a nice folder structure. Something like:
/
/Songs/
/Photos/
/Documents/
/Backups/
/Games/
/Apps/
And then if you go inside the Apps folder, you have another folder with the name of the application. Pretty much like Program Files folder in Windows.
Is this possible? For Songs, Photos, Documents, I created a folder and it worked. But what about for apps and games that I got on the market?
My SDCARD has also a lot of folder/files that were copied when I put the sdcard on the device. I don't know if I can delete that. Any idea?
Thanks for the help in advance!

noob needs help! where is the root of the sd card?

I have the froyo update zip on my sd card. I moved it to downloads thinking that's where it needed to be since it was saved in my xscope downloads. I did the 3 finger salute and it shows an option to apply update via zip, but it says no file is found. Where do I need to put the file? I have es file explorer and andro zip. Thanks.
you need to move it from downloads to the entire section. If you do from downloads and go up one file, that is the SD card.

I don't know where it needs to be, but if you are looking for root... that is not in a directory, by definition. It's as high up as you can be while still in the SD card.
Root of the SD card just means it's not within a folder
Im sorry I still don't understand. Do I need to unzip it first? It shows it's at the bottom of the list in the download folder.
Don't unzip it. Move it from the download folder and leave it outside of any folder
Put it where it was before you moved it to downloads.

Here is the closest I can get to a guaranteed noob-proof explanation:
Rooms in your house are like the folders, leave the room and you're into the house (the root of the sd card)
bah! I got it guys. Thanks. Just had to hit the up arrow in andro zip and move it there. Thanks fellas.

{HELP}lost in LOST.DIR

i'm not sure if i'm on the right place for asking this but i have no other place to go.
when we put an sd card a folder with the name LOST.DIR is created
once when i inserted a sdcard that is not the usual that i use, i found that many of my files, such as music, pics and docs, are missing and a large number of files are iin the LOST.DIR folder. i suspect that those are my missing files, however they very far from being usefull.
i would just like to ask is there any hope in recovering those lost files?
I hope you know how to unmount your SD card before removing it from your phone.
Well I know about that
Settings>sdcard and phone storage>unmount sdcard.
Is there a chance to retrieve those lost files, or are they gone for good?

the files are still there in LOST.DIR
You have to add the file type back to the lost file. I believe you cannot get back the name you given to the file or dates.
I got many large files size in LOST.DIR if the phone fail to boot, I dont know if this right or not

LOST.DIR????
i always deleted tihs folder.
but always there again....
and i never have bad experience after i deleted that...:highfive:
LOST.DIR can (gently) describe as the TEMP folder for Android, as in the% System% Windows / Windows / TEMP is the case.
you can delete it 10000000000000,it comes back.so its not necessary to delete these files it comes back.

[Q] astro file manager questions

This is my first android phone and have to admit i know very little about the technicalities of mobile phones although I consider myself very knowledgeable with anything to do with computers.
I recently installed astro file manager so I could move, rename file and folders. While exploring the file manager I noticed and mnt folder containing an sdcard folder, another folder called sdcard in the main directory and the emulated and sdcard0 folders contained within the storage folder. All the folders seem to have the same files and folders. Could anyone tell me the difference between the four folders. Sorry if it's a very noobish question.
Also can any one tell me why whatsapp images remain in the same folder in gallery although I have moved them in the file manager
Thanks
It's there for other devices. Tablets in 4.2.x has multi users. So storage would be separated between the two. It is called emulated to emulate the old folder naming scheme before 4.2.
Just ignore it, shouldn't make a difference.
As far as your folder and whatsapp, it needs to research it's contents. Restart your phone or plug it in via usb and unplug.

ES file Explorer

Hi
My SM-N9005 running Android 4.4.2 stock ROM got really sluggish so I connected it up to the laptop and transferred my images etc across to my extsd card, just drag and drop between int and ext storage, I didn't copy to laptop first. Now when I go in to ES file manager some of the folders are there but no images in the folders and I also transferred a few word docs that don't seem to be there. I know that you can't write files to the extsd card anymore but I thought you could read the files. Have I done something wrong?
Jon
