So if you have many different folders with images you can simply scan them sequentially without the list being cleared when you start a new scan. all the bad file formats that still render correctly will move to the bottom letting you focus on the more serious cases).Īlso if the first scan has finished and you start another scan, the results will simply be added to the list. Sometimes the image will be damaged and you'll see something like in the screenshot above.Ī very handy trick is click in the column header on Reason and the images will be sorted according to how badly they're damaged (e.g. Other times the image will not render at all and the preview will be just black. Quite often a image will only have a minor issue with the file format and the image will still look just fine. If you click any image on the list, it will show a preview of what the image looks like. Any images it finds that are not perfect will show up directly in the list. While it's scanning it'll show a progress percentage in the status bar. If you want to scan a lot of pictures this will take some time, because the program needs fully load and parse the image file, so you might want to let it run overnight. The program will then start scanning the folder and all subfolders for images (.jpg. Since I stumbled across this while trying to answer the same question I'll add another great solution I found:įrom the menu select File > Scan and then use the file dialog to browse to the folder in which the images are located. (A third one wouldn’t even upload because it doesn’t even have the correct header!) It’s so damaged that it doesn’t display anything. Moreover, because some picture formats embed a smaller version of the picture as a thumbnail, scanning the thumbnails for corruption is not reliable because it may be intact while the actual file (i.e., the picture when viewed full-size), could be corrupt. Some of them are not even real files at all (the recovery software merely dumped the clusters that were pointed to by now-overwritten directory entries), while others are broken because of fragmentation. I’ve used several different file/photo-recovery programs, but naturally, they are limited in how much they can recover (though fortunately the volume has 8KB clusters, which helps somewhat).Īnyway, some of the larger files, that were fragmented, are now corrupt. Does anyone know of a way to check graphics files (particularly JPEG, GIF, and PNG) for corruption (preferably in an automated way)?Ī few days ago, a command worked incorrectly and ended up deleting thousands of graphics files from a FAT32 volume that was practically out of space.
