practice, these limits should not prevent protecting all of the documents on a
computer since for reasons of compatibility with the different file systems
(e.g. FAT32), none of the software commonly used creates files larger than 2 GB.
If it is necessary to lock folders containing more than 2 GB of data, they are
therefore necessarily contained in several files of compatible size that can be
locked independently or divided into sub-folders that can be locked without
problem. This has the added benefit of faster access to protected data and
increased security by avoiding unnecessary unlocking of an entire large
So when a folder contains a large number of files, you will
directly lock the folder, and when a folder contains large files, you will lock
the files independently.
