files disappeared when moving to external sd

I was moving some files to free up some space on my sd card. I use root explorer to cut and paste a group of files. When I pasted the files I got an error saying" file too large". I thought that the files didn't get transferred but I noticed that the storage had gone down. I've searched everywhere in root explorer to try to locate files but could not. I use the app undelete to try to find the files but could not. Where did the files go?

If you were moving a large file, like movies, it's a big chance that during the file move it couldn't go from ext to fat32 and it corrupted and that's why it got whipped out.
It shouldn't happen but it's a great possibility. Word to the wise always copy the files then delete the source and careful with the large files, it's easy to forget when changing file systems.

So there's no way to recover them? I am going to start backing up more often.

DCIM on Internal SD has 830 mb...Can I delete it?

I opened the folder of DCIM on my internal and nothing is there. However, it is reading that there is 830 mb of photos and videos that are there.
Is it safe to delete this folder?

i would double check and make sure all your pictures/videos are saved on your external sdcard first. And if they are, well then by all means delete that folder.

check to insure you do not have subfolders (camera) somewhere in that folder. I deleted my "dscim" thinking that there was one item in it. Deleted all of my pictures on my phone.
fortunately i had a back up for most of them, but ended up losing a lot of pictures!

[Q] Can I delete .asec in .android_secure?

My internal storage space total only 1.3GB only. I checked on computer and found '.android_secure' folder in my internal storage. What inside it is '.asec' files. I noticed that all the files named after app i installed. But surely I had uninstall all the app.
The files example :
com.creativemobile.DragRacing-1.asec
com.halfbrick.jetpackjoyride-1.asec
com.imangi.templerun2-1.asec
com.julian.fastracing-1.asec
com.kiloo.subwaysurf-1.asec
and many more!
These files killing my space. It takes 750MB. I cannot done my CWM backup because of these '.asec' files.
My questions is, can I delete all the '.asec' files? Really need to dump it.
Thank you.

Probably you can delete those files which you really not worried about the data & settings being lost

[Q] Space not freed after messing with .thumbnails

Heya guys,
this is mostly a copy of a thread I created in a device-specific forum (original thread), but since nobody was able to answer the question there and considering it doesn't seem to be device-specific after all, I figured I'd go ahead and ask here as well. The copy & paste part begins here, with slight modifications:
A few days ago, I found that I was in dire need of some more free space on my Samsung Galaxy S4 / GT-I9505's internal storage and found that only the contents of /sdcard/DCIM/.thumbnails were taking up space. After a while of trying to get rid of those files that kept creating themselves again, I followed some advice I read on an Android forum: I deleted the contents of the .thumbnail folder, went to Settings -> Apps and cleared the data of the Gallery and Media Storage apps, respectively, before rebooting the phone.
The contents did disappear for good, but neither Total Commander nor the list of installed apps in the settings nor the Storage summary in the settings showed any different amount of free space than before. To make matters worse, the number didn't even change after I found and deleted about 1 GB of files left by an already uninstalled app, i.e. it seems to be stuck on that value. At the same time, SD Maid tells me that I should have a good 5 GB of free space more than the system is showing. Neither restarting nor wiping the cache and dalvik cache helped.
My rooted GT-I9505 is running this unofficial port of AOKP 4.3, Milestone 1, and version 6.15.6 of PhilZ/CWM Advanced. I'm not sure whether there's more information I might need to provide, other than that the size of the thumbnails files apparently exploded (about 4 GB) when I moved quite a lot of data and obb folders to my external storage using FolderMount.
I didn't find any information about this kind of problem anywhere and am afraid I messed up so badly that I might need to reflash...or worse. Do you have an idea how I can try to fix it?

You could try installing Disable Service and forcing the media indexing service to never run.

Thanks for the input! That sounds like a plan, but I'm not really sure whether I'm doing it right. I got the app, figured the media indexing service had to be found in the Media Storage app's entry, but I only found "MediaScannerService" and "MtpService" there. Since I try to be more careful now, I'd rather not deactivate any of those without being sure that it is what I am aiming for.
So, long story short: Is either of those the media indexing service or do I have to look somewhere else?

Best thing to do is delete the .thumbnails folder in DCIM folder. After this create a new file with the name .thumbnails in the DCIM folder.
Note: You have too delete .thumbnails FOLDER and create .thumbnails FILE. You can use es file explorer to do this.
It is based on the simple principle that in Linux ext file system a file and folder cannot have the same name.

While I wasn't sure it would help, I tried what you suggested. Alas, it didn't work; the .thumbnails folder is empty without freeing the space taken by its former contents since I did what I described in my original post, after all. However, should I manage to fix this problem with a reflash, I suppose I'll do just that, replacing the folder with an empty file of the same name. Thanks.

It works for me.
I 've uploaded the image of DCIM directory (folder). In place of .thumbnails folder you can notice .thumbnails file.

recover lost photo with root access

hello,
I have a xiaomi redmi 9 pro phone.
rooted.
I used fstop app to move 80 photo from internal memory to sdcard. sdcard was full and the move has been done and create 0kb file in sdcard.
Photo from inernal memory have been deleted by the app.
I used a lot of app to look for my lost photo but I don't find stuff. I found a lot of "not deleted photo". I don't find any usefull tool that could ignore not deleted files (whatapp and my personnal photo are quite huge, more than 4000 photos).
also I'm surprised not to find a lot of thumbnail because there should be a lot of thumbnail on my phone and also a lot of deleted thumbnail.
I have the date and name of deleted photo isn't there a clever tool that exist and could find them ?
using tool like diskdigger or undeleter that need root access, I don't find stuff, even when looking in a lot of volume. What I'm missing ?
My dream tool :
look for really deleted file
if there are real file : filter by folder, by filename, date, etc.
do you have some tips for me ?

If you have rooted your phone and used several Android recovery tools, but none of them have scanned your lost photos. It is possible that they have been overwritten by new files. The overwritten files cannot be recovered.

That's what happens when you MOVE a file from one drive ( internal sdcard ) to another drive ( external sdcard ):
The file contents are copied in full to some location on the target disk drive.
The directory of the target folder on the target drive is updated to include the new file copied.
The directory of the source folder where the file used to reside is updated to no longer list the file. This causes the actual data for that file on the source drive to be released and marked as unused space.
