Google blocks the Write ability for third party apps on Android 4.4 KitKat update for uncertain reason. File managers can’t access to SD card at all and lost the ability to manage external storage completely.
However people always find a way to solve problem, although the solution may not be super perfectly.
I recently update File Expert and find it restored the ability to manage external SD card.
Download app from Google Play and open to start. I notice my external SD Card is shown under Folder Tab.External SD Card is accessible and writable again in File Expert. Click to enter, choose a file and try all basic file operations, create, copy, cut, paste, rename, delete, edit and zip file within external SD card. File Expert completes all without any error.
You can even explore more available actions for External SD Card in File Expert. Like trying move a file from internal storage to SD card, sharing files on external sdcard with FTP, Web PC Suite it will be done perfectly, without any error.
What file manager do you use right now? Or is there any file manager can do more?

I've only had this phone a few days, so my brief search may have missed this:
I am unable to move/copy/delete files on my external card (/mnt/sdcard/external_sd). The default "My Files" app allowed me to move a couple of files, but not others. But my favorites, "ES File Explorer" and "Root Explorer" seem completely unable to do anything but read files. How can this be?
If it matters, I'm rooted.
It u are cutting and pasting or moving files files to and from external to internal, mine doesn't work either. Move within the same or copying files however seems to work.
Can u delete?
I can delete some small files. But copy/paste from within external just fragged an entire folder...
Okay, here's a guess - I used this card on my Atrix that just died, which ran CM7 with ext4 formatting kernels. Should I just reformat the whole thing?
do a low level format. Use a micro sd - sd adapter and then use this free program:

afterwards you will have to again format it to fat32 in Windows.
It does sound like the sd card is corrupt
I'm having a big issue getting the Android File Manager to grant permissions to write to the SDcard for 3rd party apps. In order to grant permission. One must select the external storage. Doing so will enable to app to modify the contents of that storage. However, my phone does not detect the external storage as seen below ..
(Check attached file)
My situation : I have TTorrent's download directory to my MicroSd -- so as to not waste internal storage. I downloaded a .rar file and it saved to the sd card. I want unpack that file, but I must grant ES File Manager permission to do so. It prompts me of what I need to do. I have the 'Show SD Card' toggled on, and yet my external storage doesn't show.
I have formatted my card using Android's format system.
I have formatted using Windows in both NFTS (Wasn't supported) and exFat.
I have tried mounting and unmounting and restarting the phone.
Yet to no avail ...
This is not an issue with ES File Manager, as I have used QuickPic to attempt to delete pictures from the MicroSD, It asks for permission, and again I cant grant it, because external storage doesn't show even though it is mounted.
What do I do ?
Update:
Apologies, there was another thread on this topic. I got it to work thanks to this thread ! >> http://forum.xda-developers.com/showthread.php?t=1773735
SDcard just needs to be formatted to exFAT and the external storage will show for 3rd party apps. At the unfortunate sacrifice of 4Gb file limit sizes.

You mean it needs to be formatted to fat32 correct? That was the solution posted here in the alcatel forums, and it is what you're linking to in your post.. just don't want any newbies getting confused
It seems there is a security flaw when copying files from encrypted internal storage to encrypted sd card with third party tools.
I have installed a micro sd card and enabled encryption on external sd card. After every boot I get a notification that external sd is encrypted. If I put the sd card in a card reader on my pc, I can see the directory structue and file names on the sd, but I cannot see the contents of the file, because they are encrypted. So far this is expected behaviour.
Now the unexpected part: sd card is installed in phone (no pc involved). I copied files with solid explorer from internal storage to encrypted sd card (side note: i noticed solid explorer cannot access the copied files). I reboot my phone and suddenly it says "encrypting files on sd-card" and a percentage counter went up while the newly copied files get encrypted? Huh !? Second test: I copied files with solid explorer from internal storage to encrypted sd card and shut down the phone, put the sd card in a card reader on an pc and - guess what - the copied files are unencrypted. They get encrypted after next boot in the phone. This behaviour does not occur, if I copy the files with samsungs integrated file explorer. Files copied to the enrypted sd card over mtp connection are encrypted immediately.
I have experienced something similar. I wanted to create a directory on encrypted SD card in ES File Manager. It displayed the message like "...will be created asynchronously" and zero length file was created instead. After reboot and encryption the actual directory was created.
It seems that third party file explorers like solid explorer or ES file manager can access those files/folders (created by themselves on encrypted sd card) only after the files/folders got encrypted after reboot. The flaw I see here is not only that files unexpectedly remain unenrypted on sd card, but also that files are written unencrypted at all and only get encrypted later. There may remain unencrypted parts of sensitive data that someone might be able to recover from sd card (with a data revocery tool).
Sounds like those developers need to update their apps to support Marshmallow's encryption. In the meantime, if you've got sensitive files to copy, use the built-in app.
It seems, that there is some scheduler running encryption over the night. I created a folder on SD card as usually - no folder, only empty file was created initially - and next day there was a folder; without need of reboot.

I tried the same yesterday. I copied a file from internal storage to encrypted sd card with solid explorer and the file is stored unencrypted with 0 byte length. 24 hours later it still remains unencrypted with 0 byte length. Maybe there is something else that triggers the encrpytion (except reboot), but not sure what it is.
EDIT: 48 hours after copying the file it finally got encrypted.

Hello,
I'd like to create a shortcut or link inside the internal memory folder to point to the external SD card. (Like a shortcut in Windows Explorer.) If I have to use symbolic link I will but I'm afraid this would mess up some apps that scan the internal memory (send it into a circular loop.) I am trying to access the SD card quickly from within the internal disk, when any app shows me that folder. (Basically some apps like CameraMX are STILL failing to show the SD card, even with Root.)
Can anyone help me create the shortcut or link? My mount point for SD is: root/mnt/media_rw/6664-6330. My filesystem is NTFS.
I have: Root Explorer, Solid Explorer, MiX, Terminal.
I tried searching google and XDA but it's hard to eliminate threads talking about the homescreen or adoptable storage. Sorry if this has already been discussed.
Hey
With the new android update for this phone i can no longer browse to the sd card via the directory of device\
usually there is a link to the external sd card in device\storage but now its all empty there and i can only access the internal storage via Device\sdcard.
If i use a file browser like Es media then u can select the external sd card directly and access it. But the problem im having is when im in simple apps like ePSXe it wont let me reach the external sd card since i have to manually browse to it but there is no shortcuts to it anywhere. There was one app that allowed the full path to be manually added which worked since the folders are hidden or something.
Its like samsung have hidden the folders link to the external card.
Is there a way to create a shortcut from the internal storage that point to "device\storage\D8C7--9661" (which is my external sd card)?
