I can no longer repro the issue, regardless of the destination folder I choose in the Import wizard. It cleans the (acq*.tmp) temp files duly this time. 3000+ items copied in a single go. that's strange!
Either because I ran Chkdsk on the system drive, or I'm running v22H2 (when the original question was posted, it was v21H2).
That is strange to me because my S8 has alot more files and only around 1800 pictures and videos are detected. I dont know why. My windows version is also 22H2 with all updates. What kind of PC system are you using ? How did you use Chkdsk ? Also, did you use the command line to clear the temporary files or the script that you told me to use? After all this time, I am still getting all the thumbnails being switched with another picture and also problem with sizes. What steps did you take to resolve this on your end? What phone are you using?
