Reusing a Drive Mapping
Depending on the value of the UseExistingMappings flag in LL.INI, LinkLaunch can map a drive to a previously unused letter, or
reuse a letter that is already mapped to the correct drive.
Each time LinkLaunch reuses an existing drive mapping, it increments an
internal use counter for that drive letter. As users close applications linked to
that drive letter, the use count is decremented. When the use count for that drive
mapping reaches zero, the mapping is deleted. LinkLaunch never deletes system
drive mappings (those created outside of LinkLaunch). It only deletes the
temporary mappings that it creates.
