How to Fix Location Is Not Available the File or Directory Is Corrupted FIX

I can't select windows button 😰😰😰
what can I do now??

I cant open any file. says 'location not available' 😢. Help

worked like a charm . pc is being analysed now or w/e. Don't know how long it will take :p edit: ok it took about 15mins and corrected some errors and deleted the pesky empty folder that started me looking for this fix. thank you :)

I did that and it said file system is raw

Wat causes "location is not available the filename directory name or volume label syntax is incorrect." to happen to some off the files on a sd card ?
