security - How to have an USB drive readable by all but writable only by me? -


i have files (document word or pdf) written on usb drive given second person cannot control. need him not able in way modify or delete files drive, needs able read files or print them. person able delete or modify must me. imagine have use type of password system... how supposed do?

as far know can done @ either application level (for example using adobe acrobat or microsoft office security features) or file-system level (file permissions).

the problem application level security limits number of file types can share, in case you've specified pdf , ms word, both of have protection features, depending on versions you're using.

the problem using file-system level permissions none of file-systems permission support in general use (ntfs, hfs+, ext3/4) compatible across platforms.

in case i'd convert them pdf , use pdf protection features.

edit: don't think you'll able prevent user deleting files @ all.
