### Directory timestamps aren't preserved

Rclone doesn't currently preserve the timestamps of directories. This
|
|
|
|
|
is because rclone only really considers objects when syncing.

### Rclone struggles with millions of files in a directory/bucket

|
|
Currently rclone loads each directory/bucket entirely into memory before
|
|
|
|
|
using it. Since each rclone object takes 0.5k-1k of memory this can take
|
|
|
|
|
a very long time and use a large amount of memory.

|
|
|
Millions of files in a directory tends to occur on bucket-based remotes
|
|
|
|
|
(e.g. S3 buckets) since those remotes do not segregate subdirectories within
|
|
|
|
|
the bucket.

### Bucket based remotes and folders
|
|
|
|
|
|
2020-08-03 20:51:52 +00:00
|
|
|
Bucket based remotes (e.g. S3/GCS/Swift/B2) do not have a concept of
|
2019-08-04 10:43:10 +00:00
|
|
|
directories. Rclone therefore cannot create directories in them which
|
|
|
|
|
means that empty directories on a bucket based remote will tend to
|
|
|
|
|
disappear.
|
|
|
|
|
|
|
|
|
|
Some software creates empty keys ending in `/` as directory markers.
|
|
|
|
|
Rclone doesn't do this as it potentially creates more objects and
|
2020-08-03 20:51:52 +00:00
|
|
|
costs more. This ability may be added in the future (probably via a
|
|
|
|
|
flag/option).
