Hello folks, I have a question that I'm hoping you can help me with. I work on files from my Flash drive on a public COMPUTER. I'm WONDERING if someone can view those files after I remove it from the computer. I'm not copying the file to the hard drive. Temp Files could remain. If your allowed to accidentally safe file to Hard Drive it can remain. If shadow copy is enabled it could remain. If there was malware that is out to steal info it can GRAB and store it in a hidden area as a pick up location for a hacker. If the memory blocks that the file was in are not overwritten in RAM, it could remain. If there was a share somehow to the USB drive at say Letter E: and someone else knew that you had connected a thumb drive and could remotely get to the thumb drive they could see and grab data etc. If a file was detected as a false positive or an actual virus, your file would be placed into quarantine in which its contents could be viewed by an administrator.

Most COMMON would be temp file data or accidentally SAVING it to default location on hard drive vs thumb drive. Other ways are less common.
