hello is there anyone here tell me what is logonui.exe? Is it a virus? bcoz when i when i tried to open my sd card the only FILE i see is autorun.inf. but when i right click the sd card it has a used size of 93 mb.. so i go to command prompt to check if the file is only hidden but it show only two file the autorun and logonui.exe.. is anyone there HELP me how to fix this problem..  Thanks in advance..What brand is the SD card? Some SD cards come with a program that is SUPPOSED to be ran when you insert the SD card. If you dont need logonui.exe, deleting it shouldn't hurt anything. Also, a LITTLE bit of space is always used up, even when there are no files on the device.its kingstone 2gb.. is there any hope that i can view the pictures.. and what should i do.So you when you try to put pictures on the card, then you look on the card, the photos dont show up?
Or have you not tried yet? Oh, and do you have an anti virus?i used the card last saturday in a camera, then now i try to transfer the picture from sd card to my computer but all i can see is autorun.inf and  no other file inside it..yes i do have a anti virus on the other computer its mcaffee 8.7i.. but i did not make a scan yet coz i afraid to lose any picture..  have you already meet this kind of error mr.helper?Could you have accidently deleted the pictures from the SD card on camera? Try taking another picture on the camera and see if it shows up on your computer.no i did not DELETE any picture in the camera.. the logonui.exe is use application in sd card.. 93mb used space of my sd card is really the one that catches my attention.. and when i open it i can only see the autorun.inf and it has only okb size..Every drive, even when it has no files on it, uses SOME space. A 500 gigabyte hard drive shows SOME used space, even when no files are on it. And this applies to SD cards too.yah your right.. i tried it to my computer and format one of my partition. after i format it, even though you cant FIND file on it still it has a used space.. maybe its because of the system volume folder and  other protected operating system file that are hidden.. is there any chance that i can recover the lost file.?but i think its to strange for the sd card to have a 93mb used space because i a thumb drive can only have a 4 kb used space, and a hard disk partition is 67.9 mb.. i think there's really something wrong in here..dude thanks for the help.. i already fix my problem.. thanks you for the time.. godbless dude..Don't mention it.  I like helping people. Oh and, by the way, the amount of space that is always used depends on the capacity of the drive.
