Anyone who can explain to me what the folder LOCKS contains?
There are files with names such as
_18CFB25F-8F49-A81D-A518C4E6D442.LT.

In Document Library when I click Show Actions on some documents
I get the question if I would like to Open or Save the document
to my computer.

Some users with the proper authorization can not create a Network
Place in Windows Explorer.

Three questions at the same time, hope to get an answer to them
because our users will strangle me if I don't help them soon.
