Deleting system files

Is it possible to delete any files in the system directory? I can save close to 16 megs if delete the ring tones/notification tones/alarms that I'll never use. any advice?

Yes it's possible, but I don't think it will do you any good. As I understand, internal memory is in the data partition, and deleting files in the system partition doesn't give you any more space in data...

So what can we delete to free up space for apps?

Download and use a script to move apps and cache to your SD

As mentioned, your best bet is to move stuff to the SD card.

meh... i guess that's our best option. thanks for your help.

[Q] App2Ext on Milestone - CyanogenMod 6.1.2 - 0.12

Hello guys!
I have a Milestone and I'm using the CM6 ROM from milaq which is pretty good!
It has the scripts to make App2Ext works built in: 05mountsd and 07app2ext.
I partitioned my sd card like this: 6 GB to FAT32 and 2 GB to EXT3.
Just this and everything works, because I saw the "/sd-ext" in the ES Explorer. When I installed some apps at "Internal Memory", this apps appeared inside the "/sd-ext" folder.
But, some things seems to be strange for me:
1. When I went to "Seetings > SD card & phone storage > Internal phone storage", the "Total space" doesn't change. I mean, the "Total space" from "Internal phone storage" continued with 197MB like before activate App2Ext. Is this right? The space from ext partition shouldn't be understood as "Internal phone storage"?
2. The phone seems more unstable. I had some reboots when I was installing some apps and sometimes some widgets doesn't load. Is it normal?
3. My method is it ok? Just to create the ext partition. Should I make some other things?
Thanks!

1. Correct. Internal space is not ext space.
2. Widgets cannot be installed on ext partition. It has to be on internal memory.
3. Yes.

But when I activate the ext partition, how can I do to install apps at "Internal Storage"?
I mean, after I activated the ext partition, all the apps were installed over there.
The "Manage Applications" say those apps are installed at "Internal Storage".
Thanks for reply!

You have to move it using apps like rootexplorer.

Some friends with other phones (like galaxy 5) activated App2Ext and the "Internal Memory" goes up!
Why this doesn't happen on Milestone?

That's probably becoz dalvik-cache is moved to ext partition as well. Milaq's CM6 uses CM7 app2ext which leaves dalvik cache in internal memory and only moves data apps to ext partition.

Yes, you have to modify the script to do that. Check this link for the modified script.

I need your help guys: For the first time I need to install many apps and the 190MB aren't enough. So I wanted to use apps2ext. Since I've never used it before I don't know where to start. (Format card, what to install then, if any scripts are needed, etc.)
Is there any guide somewhere?
Sorry if this has been answered before (I'm pretty sure it has... )
Thank you for your time.

This might help. Read instructions carefully before trying.

You don't need to do anything. The rom has app2ext built-in. You just need to create the ext partition.
Also note that CM7 based roms don't move the dalvik-cache to ext partition. You need to modify the script to do it. I have posted a modified script for that in the same thread. Check the last 2 pages.

1. Yes, to increase stability.
2. Don't move. It is better to leave it in internal memory

Stability and performance of the apps will be affected.
Sent from my Milestone using XDA Premium App

Hi, I use froyomod 2.9.3 and I used to use i&f 4 but, I saw better performance on tfm so I switched over, I used to have an ext4 partition but none of the apps showed so I went back made a list and dloaded them again. But the internal memory kept dropping every time I installed an app. w 70 apps my int mem only had 19 megs left. But my ext partition still had 100 mb left (verified using free space- krikun). Please help cuz I cant install any more apps

(Q) Ext4 on latest CM7 Kang Milestone

I finally decide to have a partion on my 8GB SD other than FAT32. So i used the FuFu Minimod to split my SD. First to Ext2 then to Ext3 and then to Ext4.
It all went fine. I have moved some basic apps like Facebook and Igo to the Ext4 partion.
The weird thing that drove me to create this thread is the fact that my phone became a bit slow... unresponsive... and just because the Ext4 with basic apps on it?
Did i miss something or this is normal?
Appreciate all feedbacks.

Try wipe both Cache and Dalvik-Cache

Thanks... but is not the case... and yes i already did that before creating the thead.
Tks

Well then, manually move the app to the sdcard, then move back to the phone.
It should move into the ext4 partition.

They are all in ext4...

I know it is inside ext4. Please try to move to the sdcard and back to the phone again.
I did face this b4

I have done that before you mention... and it looks like its a bit more stable.
One doubt... i notice that all sd-ext\app files are alson in data\app.
Why is that?
Sent from my Milestone using xda premium

Why
Is ext4 faster or what ?
Im kinda noob on this android and stuff things, so i donno.
I can put my apps on SDcard without formatting to ext2, 3 or 4.

Well, now after billions of testing, formating, reflashing... all looks pretty nice now.
@ivanotera: moving apps to sdcard is not the same as moving apps to a second partition where this second partition is journaled - case of ext4.
It means that when you boot your phone, this partition is ready to use and does not need to be "prepared" as the usual fat32 - thats why we see the message after boot up that sd card is being prepared (in fact the OS is checking if the partion is corrupted or not.
Also when moving apps directly to sd card like you are doing, is not good as phone becomes slow, widgets, shortcuts dissapear while booting phone and while phone is connected to pc via usb with sd mounted for access.
With ext4 (using ext4.ko module) OS will think that this second partition is part of the internal storage and all of the above mentioned will not be a problem anymore and you will not get that anoying message that you have not enough space just because you added a couple apps.
Hope this can clarify some important things.

Yeah, got it.
But another question, is ext4 "viewable" by windows ?
Because i have a 32gb card, so i use it as a "pen drive", have some apps so when i format a pc, not at home, i have some apps already, and dont have to download it.
Or in the case of creating a ext4, i partition the sdcard, so i have the "apps" partition and the "windows" partition ?

Hi,
Link2sd can not link all data to sdcard. It leaves files in \data.
Some apps use cache, and it is stored also in the external memory. There is an option in link2sd, where you can delete cache.

I never used cronmod, but as i know, it mounts the partiton like it would be internal mem. I think you should move back the apps what are linked, and before u use cronmod, delete link2sd.

[Q] New to SD-ext

Hello, I am new to SD-ext and Link2SD and such things, I googled around a little and found the most suitable solutions for the internal memory shortage of CM10.1 is either Link2SD or INT2EXT+
Now I want to ask, which is better at performance, more stable?
I would have went around experimenting as they say but the problem is that I don't know how to remove either of them, so please tell me that too, so if I didn't like one of them I remove it and try the other.
That's all for now, thanks in advance!

I would suggest int2ext, because effectively it increases the size of your internal storage instead of moving apps to sd. As long as you have a class 10 or better sd, you won't notice any difference in performance.

Unluckily I don't have a class 10 SD right now and I doubt my ability to get one for a while. Currently having a Class 4 16GB SD, what do you think would work best?

You can still use int2ext, but you will get a quite noticeable performance decrease. Just test it! To remove just go to system/etc/init.d, then you can just remove its files.

I actually tried Link2SD (With a EXT4) but it didn't read or create a script. I googled, people said use EXT2, so I just said, since it didn't work, let's try INT2EXT.
I flashed it (without removing Link2SD) and nothing changed...
I, just now, removed Link2SD and restarted: no changed.
What do you advice me to do? ((I think the problem is because this ROM doesn't support EXT4, but I am not sure of course))

Int2ext needs ext 4. After removing link2sd, you should reposition your sd to ext 4. And which Rom you have? Because current ones are all sporting init.d, so they support sdext.

Well, seems I should really change it from EXT4 to 2, I guess that's what I will try.
Thanks everyone so far! :good:

Since you have the latest CM10.1 nightly.. I suggest u try this..
Take a complete back up of your SD card.
Make sure u have uninstalled any apps and removed any scripts related to link2sd and such scripts. (When there's any doubt whether the old scripts would cause any problem, i always prefer wiping the device and freshly installing the rom to avoid any mistakes)
If u do not have any problem flashing the ROM again, i really suggest u to do so and then do the below steps. Definitely should work.
Reboot into recovery mode.
Go to advanced option and select SD partitioning option
Select the partition size as 1024mb and swap size as 0mb.
Proceed with partitioning.
Reboot your device.
Save fixed-int2ext+ for android 4.2..1 by CronicCorey on the root of your SD card..
Boot into recovery again.
Go to mounts and storage option and mount data, system and sd-ext.
Go to install zip from SD card.. Choose zip from SD card.. Select the int2ext+ script.
After installation.. Go to mounts and storage and unmount data and system and format sd-ext.
Now reboot the device and check.. It'll be done.
I have done this many times and it's worked. I use 16gb class 4.. No issues.. Smooth for me..
After installing this script.. Make sure u dont wipe dalvik cache using recovery mode. Your device will get into boot loop.. Use wipe dalvik cache script specifically created for int2ext by croniccorey..
