How to unlock document file?

Hi bro document file a lock paniten epdi unlock panradhunu solunga please

Hi bro, when you open the file within files app, you will see the password prompt. you can enter the password and unlock the file. Is it a microsoft office word document file? entha app use pannitu lock pannuneenga?

Apple oda Files app la lock panninen,open pannapo password keattudhu,remind iruku,but password a eduka mudila,

within Files App we dont password lock bro. Did you use app like Pages to create a PDF or Document File and password protect it? Can you try opening the file in Pages App and then remove password?
