When I edit photos using Google Photos, the edited pics are stored in a folder DCIM/PhotosEditor. But the thumbnails for these pics that are displayed in other apps, such as Instagram and X-Plore and Files, show the old, unmodified versions. The new edited versions are displayed when I click on such a wrong thumbnail, but not before. I have a Samsung Galaxy S10e with Android 12. I have searched how to clear the thumbnail cache, but the instructions usually refer to a .thumbnails folder, which doesn't seem to exist on my system (showing hidden files is enabled of course.) How can I fix the thumbnails of my edited photos?

Today, I was observing WhatsApp app behavior. By using a camera, I took a photo. That photo got stored in the camera directory of my cell phone (obviously that is normal behavior). And after that, I shared the same photo to one of my contacts using WhatsApp. After sharing, I deleted that photo from the camera directory and checked my WhatsApp contact (to whom I shared the photo) it was still in the list of messages. Then I found on Google that WhatsApp also stores sent images in the internal directory as well. Then I deleted the same photo from WhatsApp's internal memory and checked the WhatsApp contact (to whom I shared the photo), I found that there was no real photo but a blurry image of the same photo was there (that is called thumbnail). I tried to find out where it was getting that thumbnail. I searched my whole cell phone directory or even WhatsApp media directory as well, but could not find the thumbnail. My question is, what is the location in the cell where WhatsApp stores the thumbnails? I am assuming that WhatsApp keeps the thumbnail URL and downloads on demand. Is that right? Any help?

If I send an image/video via WhatsApp and the other person doesn't download it, how can he still see the image as a blurry image? From looking through the app's database, I found out that the local path of the image that was downloaded is located in the thumb_image column in the messages table. However, if the image is not downloaded, I don't have any information about the local path. Does WhatsApp store that image as temporary image data on the device?

I am suffering from media corruption on my SD Card, I have deleted .thumbdata file on my android phone (Samsung J7 Prime) to freeup space on sd card but after deletion all files are corrupted and showing error while opening. is there any solution for this issue?

My Google Pixel 3 phone saves videos as mp4 files that have no thumbnails in Windows Explorer. (This screenshot shows files on my PC that I'd moved via USB from the Pixel 3.) Apparently many other Pixel 3 owners report this same annoying situation; the problem isn't specific to my device. How can I make my Pixel 3 generate thumbnails properly?

A THUMBDATA file is a cache file created by some Android devices' Gallery app. It contains indexed property information about every thumbnail image shown in Gallery. I accidentally lost all my images on my phone and all I have is some files named: x.thumbdata3-xxxx they sized about 1-1.5GB each. the question is how can I extract the data inside these files? **I Don't care if they tiny sized or anything**. I managed to install some apps on android and extracted a couple of images but all the data extracted was not even close to 2MB. is there any solution for this? *not looking for any sort of online tools. Thanks.

A similar question has been asked previously, however the answer is not relevant to my problem. I have a number of photos where the thumbnail in the gallery does not match the photo displayed by the viewer (HTC Sensation, stock gallery and photo viewer). for instance, take a picture of a child on a swing. The thumbnail appears to be an image taken a fraction of a second earlier than the photo the viewer presents. The child is framed to the right of the photo in the thumbnail but to the left in the full view. Is anyone able to explain why this is the case? Also, am I able to rescue the image presented as the thumbnail (which is a better framed image)?

iOS takes a screenshot of an app every time it is sent to the background (maybe to show as a thumbnail when viewing recent apps. Details are available on this Stack Overflow question ). I did a little research and came to understand that the same feature is used by Android also. This Stack Overflow question deals with it. This is a security issue if these snapshots are being stored somewhere in the device and are accessible to other apps. I wanted to test this feature for my app, but I have no idea where Android stores these snapshots. I did some Googling but found nothing about the storage location. Where are these snapshots located? Is this accessible to users other than root?

I took some photos and when I went back to look at them the thumbnails are black and corrupted. How does this happen and can they be repaired?

I accidentally deleted the contents of .thumbnails folder in DCIM in sdcard. After deleting it I am unable to access MediaStore.Images.Thumbnails._ID however MediaStore.Images.Media.DATA is having all the images. How do I regenerate thumbnails in the .thumbnails folder to get the details of MediaStore.Images.Thumbnails._ID? I initially had the idea that the gallery app in Android generates thumbnails in the .thumbnails folder so what I did was clear the cache of gallery app. Unmounted the sdcard and mounted it again in the hope that .thumbnail folder will have all the thumbnails when I relaunch the app I am using HTC One V(Android version 4.0)

I'm using Sony Xperia Z3 and used File Commander to browse and found that I kept running out of space because of a 4GB thumbnail/preview file/folder that grows rather quickly. I tried deleting the folder, but after deleting the folder, I saw that no space was freed and it was still there. So I tried moving the folder to my SD card which resulted in 4GB of space taken up on my SD card and no space freed. I don't think I can find the thumbnail preview folder anymore, but I think new files are building up because I'm running out of space again. Does anyone know what's going on?.

Every few months, my internal storage begins to fill up. I store everything I can to SD Card, but Android has a limited ability to do so. I'm running Oreo, unrooted. The biggest dir by far is /storage/emulated/0/DCIM/.thumbnails/, which can stand around 3.1GB for some reason. I used ES File Explorer to delete it, then went to the Recycle Bin in the app and emptied it. The 3GB was not freed-up. I've restarted my phone several times, looked around for residual files, could not find LOST.dir. I'm honestly at a loss. Where did it go? How can I get the OS to free up this space? What better way can I use to get rid of this stuff?

How can I reduce/get rid of the thumbnails folder in Android that is created under DCIM>Camera. I'm aware of the fact that thumbnails are auto-generated and will be generated again even if I delete them. But the point is my device has 6 GiB worth of the thumbnails folder, I keep almost no images or videos, still, it takes up a significant chunk, I know it is to optimize the loading of images in some apps, still 6 GiB in a device which has 32 GiB storage? And the worst thing is it keeps growing, never comes down. Is there a realistic way to bring down that 6 GiB to under 2 GiB. I'm ready to repeat this process every week or so if needed, I just need some space on my device.

I am considering buying a tablet with Android, in order to navigate a particular kind of files. These files have .pes extension, and they are special files for embroidery machines, they contain the "instructions" to create particular images for the machine itself. The aim is to navigate those files using a file explorer app, for the customers of our shop: we would like to give a preview of the images in our catalogue before embroidering them. Obviously, thumbnail previews will be really useful, with no need to open every single image. But I am not able to find a single app which can provide a preview for "special" files, which are not jpeg, png, and similar. Is there a way to customize or add the type of files for which the thumbnail previews are possible?

So I recently switched to a Samsung Galaxy A50 with One UI version 1.1 build over Android Version 9. So, I've been facing an issue with thumbnails regeneration. The DCIM/.thumbnails folder keeps deleting its content next day (which I suppose is a feature to save memory). But, the problem occurs when the contents aren't able to regenerate themselves. The gallery apps itslef is working fine and regenerating thumbs properly but not creating new thumbs in the DCIM/.thumbnails folder due to which I'm unable to post on Instagram and Reddit. I tried clear data and clear cache on gallery, rebooted my device but it,s still no good.

I have 16gb internal memory in my Android phone (Asus Zenfone 5). I am using only around 3gb of memory and rest is being consumed by some hidden files. I am facing problem of memory shortage (only around 100mb left). I figured out there are two large files in DCIM folder of around 4.6GB in .thumbnails folder naming .thumbdata3xxxxxxxx . I deleted these files but the memory usage is still not reduced. Are these files not deleted? How and where can I search for the hidden files consuming internal memory? Thanks

I just don't know how to fix this issue. I have tried almost everything and give up. I have read other threads on what to do if there is .thumbdata3 file that occupies a lot of space. my file occupies almost 20 gb and I cannot afford that space waste. I have done the following to try and circumvent but nothing works - create an Empty file with the same name. that empty file will eventually increase to the same size - stick a .nomedia file in every folder that contains an image so this file does not grow in size. and then I repeated the above first... the file is still created. there are some observations have had in that regard. - initially the dummy file I created remains as it is. then as soon as I try and open or call in Explorer through some third party app for example there is an app that needs of photo to upload so Explorer is invoked through the app to choose the photo the phone then completely freaked out and Will hang and forces a reboot - why this hung state happens I open up process monitor which unlike other apps will run regardless of how hung the phone is... I find the process download manager and under that the process name is android..process.media this process strikes out as the highest CPU consumer. and within a matter of minutes the hounded 20 gig .thumbdat3 file is back. I am rooted on an Xperia Z3 Running Android 6.0. another thing that I observed -if I use any third party app that is supposed to let me CHMOD and C H O W N even though an attempt to remove write permissions. for everyone, will run without errors the file permission will remain the same they will not change. dytto experience when you use terminal emulator and SU on the prompt I wonder -if I disable manual this process android..process.media then what happens. - why is it that in spite of sticking in a ..nomedia file in each and every folder in spite of that the process will build the 20 gig file.

I thought there was some sort of problem with my camera but it works just fine except that it doesn't load the pictures i take with it. I take a picture and when i try to view it it turns out to be a black screen. And in the gallery it sometimes doesn't show at all. I also can't send them because it says "error loading media". And none of my photos in the gallery have a thumbnail. What can i do? P.S. I have the 9gag app and it doesn't load any picture on it either; as in i can't view any post whatsoever. Also with instagram.

I managed to extract jpg from Thumbdata5 . But when I opened it's Hex then there were only zeroes and in last of it there was only one photo that could be extracted Why is so On the other hand thumbdata size was 70MB Please help me Is there are more photos to be extract or not

I am trying to delete .thumbdata3-* files in my DCIM/.thumbnails folder on my Nexus 7 Android version 6.0.1 tablet as these files seem to be taking up close to 3 GB of data. I followed instructions from http://www.worldcadaccess.com/blog/2013/07/how-to-reclaim-1gb-from-your-androids-disk-space.html . I was able to delete the big files and in place if it copy zero byte ones with the same name. I see the new changed files in the folder occupying zero space but the deletion does not seem to empty the ~3GB file. On other searches, there was talk about a LOST+DIR behaving similar to a Trash bin to save deleted content, but I was not able to locate it. Is there a particular trash bin or cache location I should also check in? I do not find any searches with this particular issue and that is weird. Has anyone run into similar problems? Any help in solving this issue would be greatly appreciated. I looked at https://android.stackexchange.com/questions/63993/thumbdata-files-maxing-out-internal-sd-memory to check if the scenario was similar but I feel that in my particular issue, the thumbnail does not get deleted totally from the system as there is no reduction in space at any point of time after deletion. On the other hand, the other question talks about the thumbnail files getting rebuilt, which seems to be a different behavior.
