Playing a .3gp Video on a PC after Transferring from a Smart Phone

Hi Stanford,
It seems that your post didn’t contain any actual .3gp files just icon thumbnails.
To test my ability to open a .3gp file, I downloaded a sample at https://filesamples.com/samples/video/3gp/sample_640x360.3gp  (no audio)
and https://filesamples.com/samples/video/3gp/sample_960x400_ocean_with_audio.3gp (contains audio and video)

I was able to open them with Irfanview, VLC, Movies and TV, Windows Movie Player and Adobe Premiere Elements 2021. 

I suggest that you either try opening these on-line sample files or find other .3gp files.  If you can open them but not the files you copied from your phone, the copied files are the problem.

How did you get the .3gp files from your phone to your computer?

At Alan’s suggestion, I use Wi-Fi Photo Transfer; https://apps.apple.com/us/app/wifi-photo-transfer/id380326191
However, it is only available for Apple products.

I found the following listing for Android equivalents; https://www.coolmuster.com/android/transfer-files-from-android-to-pc-wifi.html
