Summary
You can't recover deleted Android files without help, specifically miscellaneous files in the MISC folder, without a tool like Qiling MobiSaver for Android.
"I am new to Android, and I find the cache and miscellaneous files under settings storage being useless and annoying, taking a considerable amount of memory space. But when I deleted the misc files, I discovered that I lost all my pictures and videos received via WhatsApp. They're no longer in the gallery, instead, only a black screen appears. Please help me regain photos and videos from mistakenly deleted Misc. files on Android."
Navigate to the storage section of your Android mobile, where you can see a list of app data and media content associated with your device, including pictures, videos, audio files, downloads, cached data, and miscellaneous files over 1GB in size.
Miscellaneous files refer to temporary or unidentified files, including zip, rar, apk, and other unknown file formats, such as application database, thumbnail files, font files, and advertisement files.
When deleting miscellaneous files to free up space on your Android device, be sure to identify and remove safe files only. Avoid deleting WhatsApp misc files as they may contain crucial database files or storage-related data, which can cause problems. Instead, delete unwanted WhatsApp images directly from the Gallery app.
WhatsApp pictures and videos may be unexpectedly deleted from Android due to Misc. file deletion, along with other online messaging and call apps' data like LINE messages and photos, Facebook timeline posts, Kik Messenger photos, Skype video calls, and Instagram pictures. Can the mistakenly deleted images from Android miscellaneous files be recovered?
