I would like to know: the Excel file is locked on the USB flash drive and its extension has disappeared. Is it possible to open this file now?
Hello Anna! In this case, it is very important to understand the full picture of the problem in order to resolve the issue, whether there was cloning of files with unknown permissions, such as 'chk', whether the media was checked for viral activity and whether it was tested by standard means for correct operation. One of the solutions to the problem is to use file recovery programs. There are many similar tools, but it is worth highlighting one representative – this is the 'Recuva' program. After recovery, you can use and transfer the file at your discretion. But this should be done before performing any other manipulations in order to avoid losing files.
