Moving Apps from Internal Storage to SD Card/External Storage

Been trying to figure this out for awhile, and rather than derailing the "Post your Razr M Home Screens" thread, I'd figure this would be more suitable for it's own thread in the Q&A section.
I'm looking for a method to transfer apps from the 8GB internal storage (stored on /data/apps) to the 32GB sdcard. A problem I have read from many other users is the lack of storage space and the inability to easily transfer the apps from the Applications settings (as in previous devices/ROMs).
Coronado is Dead recommended Directory Bind
Dyelon recommended Link2SD
based upon reviews, it looks like "app2sd" does not work for the M.
I tried directory bind, but ran into some issues where the app could not find my /data/app folder. For the Link2Sd, looks like I need to create another partition on my sdcard.
also, I found this youtube video for directory bind, but it's for the GS3 - http://www.youtube.com/watch?v=p8PyqCOpERA
anyone that can offer up some step-by-step instructions would be very helpful.
thanks!

[Q] Make external sdcard show up under internal storage

Is there a way to basically create a symlink to /storage/extSdCard on the internal sdcard? I'm using an app that will only let me view files on the internal card. I'm coming from an HTC phone and the external sd card appeared as /sdcard/ext_sd.
I've tried creating the symlink through Root Explorer, Solid Explorer, and manually via adb (with root). I've tried every location I can find for the internal storage (/storage/emulated/legacy, /storage/emulated/0, /sdcard). Every time it says "link failed Operation not permitted".
I'm wondering if there's a way I can basically mount the external sd card in an additional location (in this case under the internal sdcard)? I've used a custom firmware on a router before that had a flash drive mounted as both /opt and /media/USB, so I think it's possible to have a partition mounted in multiple places.
Does anyone know how to do this, or have suggestion for a different way to accomplish it? Thanks.

Would this help you?

Thanks, but I already looked into that. It won't work for this unfortunately.

I use the FolderMount app. https://play.google.com/store/apps/details?id=com.devasque.fmount&hl=en
I use it to create a symlink between the directory in data/data where Google Music stores files and my external SD card.

Thanks, but I've already tried it and it won't work for this situation.

I found the solution, registered just so I can share this with you or anyone who needs it. Folder mount didn't seem to work for me either.
There is a file manager called 'Lidroid File' and a plugin for it called 'Super mount', both are available for free from the play store.
Install them, and then you can nicely pick a folder on the internal storage to mount the whole microSD in it, simple as that!
I needed this for Samba file sharing as I wanted to see the SDcard on the LAN and give it a network drive letter under windows 7.

Any updates to your solution? Does this still work?

[Q] (Blefish 0516) How to forbid app created file/folder in ext-SD root directory ?

Thank Blefish first ,with your contribution to U8800 ,so we users can enjoy the Kitkat.
I have learned that Kitkat will forbid app create file/folder in ext-SD root directory,instead apps can only created their data in /Sdcad/Android.So my Sdcard directory will be tidy.
When I installed Blefish 0516 edition,I found the feature didn't work.
And I found in dir ./storage , ext-SD was mounted as Sdcard0 while the internal storage was mounted as Sdcard1.I think the irregular mounted sequence between ext-Sd and internal storage is the reason why the feature didn't work.
And I didn't found vold.fstab in ./system/etc , so I can't edit it to change the mount seq.
Dear Blefish guru,I am looking for your help~

Jellybean and forward use a different method now. They are not using vold.fstab anymore. Rather, /fstab.qcom is used (in our phone). It cannot be edited manually, a boot.img must be unpacked and repacked in order to do so.
Did you mention that apps can write to /sdcard/ but cannot write to /storage/sdcard0? This ROM does not enforce write permissions as KitKat does by default, so I am not quite sure.

Two days after installed 0516,many folders were created by apps in ext-SD root directory(./storage/sdcard0/),while only two folders were found in internal storage(./storage/sdcard1/).And it seems that the two folders were somthing like being created while using recovery or something like that,unlikely being created by apps.
Cause I am using another rom to find whether the seq between internal and ext-SD is normal,yet I found that in android 4.0.4 there is no ./storage,so I cannot know the seq between internal and ext-SD.

In my ROM external SD (/storage/sdcard0) is the primary storage. This means Android creates it's Pictures, Download, Music & other directories there automatically.
/storage/sdcard1 is just a storage, like USB OTG storage would be. It's not in use if sdcard0 is present (some apps can still write to it manually like Camera).
The /storage is another jb/kk feature. I did not go with the older direct mounting to /mnt/ because it's just deprecated. Mine is configured according to this (Nexus One with internal storage added manually): http://source.android.com/devices/tech/storage/config-example.html

Thanks for so detailed reply.
But I still don't understand how to enforce write permission.As a perfectionist , I really don't want to see so many folders created by third-party apps in my ext-SD.
If it is convenient for you,could you inform me the way to enable the write permission in your rom? :fingers-crossed:

Foldermount and Link2sd compatability

Hi, I'm not an expert about mods on phone but I try it..
I have got my Note4 in signature with root access and E-motion kernel r26 installed into phone. The firmware is the stock one "DPH1".
1)
I installed Link2Sd and I followed the guidelines for partitions (ext2, etc.) to install apps to sd.
Today I've installed Foldermount app to move Whatsapp in extsd and this app has formatted my ext partition with deleting of my apps.
Therefore can't Link2sd and Foldermount operate together?
2)
How can I know my sd class? I tried through Sd tools but when you want test the sd card you get an error writing buffer.
Thanks for your helps..

Installing A New ROM - How to deal with the Link2SD Partition?

I've purchased the Link2SD license and have linked around 56 apps.
Should I just reformat and create a new partition and then install the backed up apps and then proceed with linking those? Or just continue with the current partition whether it can index the old apps linking again ?
Thanks.

Should I need to format my micro sd so as that it deletes the partition as well as the linked app files.
