Android has evolved. You will encounter thumbdata3 , thumbdata4 , and thumbdata5 files. A robust viewer must decode the MDB (Microsoft Database) format used by older devices and the newer hash-table formats.
When you delete them, Android will recreate them the next time you open your gallery. The only downside is that your gallery may load slightly slower for a few minutes while it re-caches the images.
A thumbdata viewer free tool is a powerful utility for anyone needing to recover old or deleted images from an Android device. By accessing the .thumbnails folder, you can turn raw, unreadable data back into visible photos, often recovering memories you thought were lost forever.

The Google Play Store hosts a few apps that specifically scan your SD card or internal storage for thumbdata files to help you recover deleted photos or view hidden caches.
Locate the file using a free file manager app (like MiXplorer or Solid Explorer) with "Show hidden files" enabled. Step 2: Copy the .thumbdata file to a temporary folder.
Instead of reading the file as a text document, these apps scan the binary code of the .thumbdata file to look for JPEG headers. Android has evolved
