In the folder "NewFiles" I have non-erasable files with special characters in the file menu. What can I do to delete this files? I think the problem happens with low accu batterie while saving the actual track.
It might be worth trying to delete the files by opening a command prompt and using dos commands to go to the desired directory(folder), then use del *.* to delete everything in that directory. Double check that you are in the correct directory, otherwise you might delete more than expected.
If you go the command prompt route, the command above will only get rid of files, it won't get rid of the folder that contains special characters. So if you want to try the command prompt route, you'd probably get better results by using the following command rd /s e:\Garmin\NewFiles The "rd" command stands for Remove Directory. The "/s" indicates to remove the specified directory and all files and directories that it contains. If this command works (i.e. the special characters don't cause it to fail) you'll then have to use the following command to recreate an empty new files directory md e:\Garmin\NewFiles
One other tip is that you may need to run the command prompt "as administrator" so that it has the appropriate authority to remove directories and files.
Thank you for your feedback. I' ve backuped the files and than formated the drive with a windows machine (FAT32). After restoring the backup files all looks fine. Thanks.
