Cannot Access Latest Photos in My Gallery from My PC

A

AC Question

Hello,

This just happened today. I was able to transfer and copy/paste photos from my HTC A9 to my PC or vice versa yesterday. But today, when I opened my phone in my PC (connected via USB), i can access the DCIM folder. But the photos I can see are old ones, none of the new ones showed up. When I tried to copy and paste a photo from my PC to the DCIM folder, I got the error message "Cannot copy IMAG.... The device has either stopped responding or has been disconnected. Options are Stop copying or Skip this file". But my phone is connected since I can access the DCIM file. Only that I was not able to see the new photos. The last one I saw in DCIM is March 24, nothing after that. However, all the new photos after that are in the Gallery in my HTC One A9. I can see all those in my phone.

Does anyone know what could the problem be?

Any suggestions/comments are much appreciated.

Thank you.
