This question relates to recently created video clips, folders containg older clips do not crash explorer.
Reading through the posts on this subject (back in 2009/2010) seems others have experienced similar fault but via different causes. Using Canon Power Shot G9 camera and taking mainly photos but also video clip. Downloaded to computer (automatically creates a dated sub folder for each day that has something to download). On opening the folder the 'Explorer has encountered a problem and needs to close' box opens. Attempts to close the window don't work other than Alt Ctrl Del -and closing the 'not responding' prog. Older video clips captured on same camera don't do this, it has only happened in last couple of days. I assumed it was a virus (I'd transferred the clip to my daughters laptop by putting the card in the built in reader - haven't seen her since to see if she had any problems!) So I was unable to open the folder (as others said, it was during the process of creating a thumbnail on the folder the crash happens, one folder had ~30+ sub folders and the thumbs all started to populate the folders ok until it got to the recent one containing the downloaded clip) I tried to open the folder and change the view but the pc was always quicker than me and crashed before I could alter the drop down view menu. I had to use Nero disc burning software to back up the 29 folders without the video then delete the whole folder. I tried virus scan and malware scan on the card - nothing, I tried scanning the pc hard disc with same progs - nothing? In the end - as I was keen to save the video clips, I downloaded them again from the camera into a separate folder, used a DVD authoring prog to open the video without having to open the folder and then saved the video in a different folder. That worked fine, I now have a copy of the video which doesn't crash explorer. However, I tried formatting the camera card and then shooting a video clip, downloaded it to the pc - it crashed when opening the folder.
Sorry for the lengthy prose! Why does explorer cope with older clips but the new ones crash it? Is it a virus or malware do you think or some setting that has been changed on the camera/card ? Would like to resolve the issue if anyone can help.
