Ok, I think I am overthinking this so I just want to get other peoples' opinion.

 

I did a logical acquisition of an LG about a year ago. I actually got quite a bit, including pictures, videos, etc (what you would expect).

 

Now, I know with Android OS', images can exist in different locations. I have a few pictures for instance that are stored in:

shared\DCIM\.thumbnails

&

sdcard\Android\datacom.android.gallery3dcache\imgcache.0

 

or

 

shared\DCIM\Facebook\FB_IMG_.jpg

&

sdcard\DCIM\Facebook\FB_IMG_.jpg

Since there is an SD card in the phone, the picture was not only stored in the internal memory but written to the SD card, correct? Which would explain the duplication. I know that thumbnail is obviously a small version of the photo that appears in gallery (along with other photo thumbnails) and then when you select the picture and view it in full there is a separate file path for that. Imgcache allows the phone to reload the image quicker when you want to view it.

 

Is this all correct?

 

Last and most importantly, pictures in the DCIM storage. My understanding is thatthese had to have been downloaded to the phone/SD card and/or taken on the phones camera or a camera app. My main question and one that I need a definitive answer on - are the pictures stored in the DCIM ONLY pictures that had to be placed there by the user or could they be "cached" there in essence by browsing or an application. Like the Facebook picture I mentioned above. That would no be that the person was just scrolling through Facebook and looked at an image, it would have had to be downloaded to be placed on there, correct?

 

My internal logic says yes but I just want to be certain. 

 

Lastly, does anyone have any resources regard picture storage on Android?

Thanks all, I hope that was clear!

Which android version are you running?

Sdcard could be the internal memory as well.

DCIM/Camera is the default folder for the images created by the phone.
Browser cache etc will not be placed in that folder (by default).
A file can be copied or moved to the DCIM/Camera folder with any file browser.

Hope this helps

Hi @suaaj-ouhl-joia, thanks so much for the response!

 

The device is an android v 8.1.0

 

That was my understanding as well. My goal was to show that by someone just browsing pictures on the internet or Facebook it wouldn't just save it to the DCIM/SD card (like it would save to a cache) and that the pictures that exist in the DCIM folder/SD card/internal memory would have to have been deliberately taken or saved to that location. Does that make sense? Is there anything as far as white papers/manuals that would articulate that, that I could reference?

 

Thank you for your help!

It makes no sense. It really depends on the settings of an app. Some apps have settings for many things, including temporary files, some don't. It's up to the developer to set a static or a variable based path in his own app, no ?!

If it is possible, what if I set in an installed app the path for cache or temporary files in the same place where I deliberately save other files as well ? What will make you tell the file was there on purpose (created there or copied there) or it's the remnants of some temporary stuff ?!
