#### Mount as a network drive
By default, rclone will mount the remote as a normal drive. However,
you can also mount it as a **Network Drive** (or **Network Share**, as
mentioned in some places)
By default, rclone will mount the remote as a normal, fixed disk drive. However,
you can also mount it as a remote network drive, also known as a network share.
Unlike other systems, Windows provides a different filesystem type for
network drives. Windows and other programs treat the network drives
and fixed/removable drives differently: In network drives, many I/O
operations are optimized, as the high latency and low reliability
(compared to a normal drive) of a network is expected.
Unlike other operating systems, Microsoft Windows provides a different filesystem
type for network and fixed drives. It optimises access on the assumption fixed
disk drives are fast and reliable, while network drives have relatively high latency
and less reliability. Some settings can also be differentiated between the two types,
for example that Windows Explorer should just display icons and not create preview
thumbnails for image and video files on network drives.
Although many people prefer network shares to be mounted as normal
system drives, this might cause some issues, such as programs not
working as expected or freezes and errors while operating with the
mounted remote in Windows Explorer. If you experience any of those,
consider mounting rclone remotes as network shares, as Windows expects
normal drives to be fast and reliable, while cloud storage is far from
that. See also [Limitations](#limitations) section below for more
info
If you mount an rclone remote using the default, fixed drive mode and experience
unexpected program errors, freezes or other issues, consider mounting the remotes
as a network drive instead.
Add "--fuse-flag --VolumePrefix=\server\share" to your "mount"
command, **replacing "share" with any other name of your choice if you
are mounting more than one remote**. Otherwise, the mountpoints will
conflict and your mounted filesystems will overlap.
See also [Limitations](#limitations) section below for more info.
To mount as network drive, add ` + "`--fuse-flag --VolumePrefix=\\server\\share`" + `
to your ` + commandName + ` command. You may replace the names "server" and "share"
with whatever you like, as long as the combination is unique when you are mounting
more than one drive (or else the mount command will fail). The "share" name will
treated as the volume label for the mapped drive, shown in Windows Explorer etc, while
` + "`\\\\server\\share`" + ` will be reported as the remote UNC path by
` + "`net use`" + ` etc, just like a normal network drive mapping.
You must use the method of mounting to a drive letter, as mounting to a directory
path is not supported in this case (a limitation Windows imposes on junctions).

Without the use of ` + "`--vfs-cache-mode`" + ` this can only write files
sequentially, it can only seek when reading. This means that many

### chunked reading ###

` + "`--vfs-read-chunk-size`" + ` will enable reading the source objects in parts.
This can reduce the used download quota for some remotes by requesting only chunks
from the remote that are actually read at the cost of an increased number of requests.
When --vfs-read-chunk-size-limit is also specified and greater than --vfs-read-chunk-size,
the chunk size for each open file will get doubled for each chunk read, until the
specified value is reached. A value of -1 will disable the limit and the chunk size will
