Where is the thumbnails cache located of the Google Photo app? - General Questions and Answers

Where is the thumbnails cache located of the Google Photo app? android 10
android/data/com.google.android.apps.photos is empty
is it in the system folders? how non-system app can store data in system folders?
and what is the difference between "data" and "cache" in app properties?
so, the thumbnails cache is the "data" or the "cache"? and recycle bin is the "data"? why the thumbnails is not "data"?

In general:
Data is the app's "important" information. This might include credentials and settings that you generally want the app to remember.
Cache is app's temporary files. One example might be thumbnails for contacts in a social media app. These can be cleared without any major effect — the app can just download them again when it needs to — and if space is low the Android OS may remove cache files itself.

ClearTemp 1.1 - clear temp folder on Pocket PC

Looks like a great program!
ClearTemp is an application for you to free up storage space on your device. It allows you to clear temporary/unused files and unused registry keys/values on your system easily. It also allows you to clear your Recent Program List, Internet Address History and soft reset counter. You can even change the location of the temporary folders (Cache, History & Cookies) or e-mail attachment folder to the Storage Card. If you have custom folders/files which you wish to clear, you can also add them in.

[Q] Help! Duplicated photos in gallery

Hey developers, hi!!!
Always when I uploading or sending photos (via outlook or facebook), these photos appear two times in gallery.
Physically there aren't duplicated photos, it only happens in gallery app.
I've cleaned Sdcard cache, unmount sdcard, reboot phone, cleaned /cache and dalvik cache but these methods has no effect!!!
I hope that you help me, hahahahaha, it's a little ridiculous but it's really.
Thanks!!!!
Hi developers.... The solution to what I follow is to move the 100media folder to another folder (like downloads) , then refresh the gallery app....
Finally return the 100media folder to its dcim folder and refresh again the gallery app...
A simple solution heheheeheheh..... Cheers

Document Files

I'm trying to free up internal storage space on my Galaxy S4. Using ES Explorer, I found that the phone contains 9830 document files of various types! I find it hard to determine which files are associated with specific apps. Does anyone know of an easy method to determine which files I might delete.

I would not start deleting files I don't know about. Delete the ones you know for sure what they are for and you know that you don't need them.
For example, some old pictures (assuming you have a backup). Maybe some old downloads and some music.

Oh yeah, I'm very wary of just deleting files without knowing their association. Have moved pictures & sound files that can be moved. It's just going to take a lot of time.

Deleting a few dozens of large files will get you more space, than deleting thousands of small ones. And also deleting one small file could lead into some unexpected behavior of some app you would not notice now, but later.
That's why it's easier and safer to start with file you know you created and large enough to see benefits right away.
Most of those documents are app documentation. Best not touch them.
There are, however, a few other things to try that are usually overlooked when clearing up space.
- Delete the .thumbnails folder in DCIM. (You'll need to enable hidden files in file explorer to see it.) This stores a thumbnail of every image on your device and SDcard, deleted or not. Usually amounts to 6-7GB...
- Dial *#9900# and select 'Delete dumpstate/logcat' in the menu that appears. Those can amount to 2-3GB.
- Delete the Cache for the Browsers, Facebook, Maps, Instagram, Youtube, Maps etc. The Cache often isn't counted in the Total App Storage, so you can't see it. Go to Settings> Application Manager > All, click on the app and hit Clear Cache. (Clearing data deletes your profile and resets the app; the cache is just temporary files.)
- Clear the Google Play Services data. Go to Settings > Application Manager > Google Play Services. Click on Manage Space. Hit Clear All Data. Contrary to the warning message, this does not affect your account, Gmail, calendar or contacts.
- Clear the Cache of the phone. Boot into Recovery and select Wipe Cache Partition. This is just temporary files, no actual app or data is affected.
- Go to Settings > Storage. Tap on Cached Data. This'll open the Delete option. (Mine just now was 1.8GB... ). Might give a Security Policy error and appear to do nothing, give it a minute. You can also hit Used Space to see what uses the most space, and hit Miscellaneous Files to see the separate folders that use up space. Select the ones you know for certain are useless (Old apps, for instance) and tap on the bin icon to delete. (Thumbnails was listed here for me as well.)
That should clear up a few gigabytes.
P.s. This'll list Google Play Services, Package Helper and some other processes in your Battery usage as high usage for a minute or two. That's normal. The apps have to actually work for a change

Go to Settings, Apps, Show system apps, find Media storage, select Memory and clear cache and data. Reboot the phone.

Find Media Storage, then select Memory and it shows just average RAM use, frequency, etc.
If I select Media Storage , it shows clear data, but cache is not enabled. So I did clear data, rebooted, seemed to do the trick, thanks much!!

MIUI Gallery reverse engineered

In the MIUI Gallery app data we have a picture database /data/user/0/com.miui.gallery/databases/gallery.db containing information such as timestamp, exif data and file name.
There is a cache directory /mnt/runtime/write/emulated/0/Android/data/com.miui.gallery/files/gallery_disk_cache/full_size containing thumbnails in 1080x1440 resolution.
How does the MIUI Gallery app know which preview belongs to which picture?
I am looking for information about the missing link. I have attached example app data for one picture. The original example picture is included.
The goal is to recover metadata of pictures. I lost the phone and MicroSD Card so the original photos are lost. But I have a f2fs disk dump of userdata partition, that allowed my to restore at least thumbnails of lost pictures. The goal is to find the link to the database entries, so I can at least restore the timestamp and file names.
My first attempt was to simply rename the files by mtime (see shell script) but unfortunately that doesn't reflect the correct timestamp, because that is only the creation date of the thumbnail (when first opened a picture in gallery)
