So, you can download a deleted file from the WhatsApp folder with the path sdcard/WhatsApp/ only if you have the message in the chat.
Also, WhatsApp, which has introduced Unified Payment Interface (UPI) service for users to transact money in India, is also testing the Quick Response (QR) code scan feature. But now those files can be re-downloaded, thanks to the latest update. Users were quick to spot the bug, and as a result, WhatsApp app rolled out a fix in version 2.18.112 on April 14.
WABetaInfo points out that undowloaded media is now stored in WhatsApp's server for 30 days.
Being a beta tester has advantages and disadvantages - you get access to the latest features and updates before anyone else, but you have to suffer through glitches and bugs. Separately, a WhatsApp beta for Android update (v2.18.111) reportedly added the vCard indexing feature.
As per a report by WABetaInfo, Whatsapp now allows download of deleted media files like images, videos, GIFs, and documents from Whatsapp's servers. However, now, WhatsApp does not seem to delete the data from the server and that enables users to download it again if it was accidentally deleted. According to a report by WABetaInfo, this feature is available for WhatsApp's Android users. It has chose to store all the messages and multimedia content on its server even if it is downloaded by the user. Earlier, the company would let the recipient of the media file to download it within a period of 30 days, after which it was deleted from the company's server and hence couldn't be recovered unless the sender releases it again. It took several trials to download the files deleted 3 months ago. For now, this new feature is available only for the Android users and further tests are currently underway. However, as per some sources, Whatsapp is now not allowing media files that are too old to be downloaded again.
