6.7.7

  • Allow installing without administrative privileges
  • Apply a more modern look to the installers

6.6.3

  • Support for High DPI displays
  • Ability to map to a single bucker/container

Fixed Issues

5.6.24

New Features

Missed Upload Sweep
  • Drive now looks for files in the cache that have been created or updated but not uploaded. Sweeps are performed after 1 hour of drive inactivity, looking for files modified more than 45 minutes ago.

Fixed Issues

  • Fixed marker handling for more than 5000 items (Azure)
  • Could not upload large files (e.g. 6 GB)
  • Drive renaming “New Folder” generated an Authentication failed error

5.4.10

New Features

Support for Files Larger than 5 GB
  • S3-based drives now support MPU (multipart uploads) required to upload files larger than 5 GB.
  • OpenStack Swift drives support DLOs (dynamic large objects).
Durable Upload Cache
  • The pending upload queue is now stored on disk rather than in memory. This provides robustness for application/OS restarts when uploads have not completed.
  • The Drive cache is no longer cleared on reboot. The default location of the cache is now %LocalAppData% (from %LocalAppData%\Temp).
  • A new option “Verify Upload” adds an extra check to the drive upload. The uploader makes an additional HEAD after a successful PUT to verify the file size. This setting is not necessary for normal use.
Ignore Temp Files
  • Filenames matching exclusion patterns can be created or downloaded on the drive, and updated, but will be ignored for upload. For example, *temp.txt.
Introducing Log Files
  • Logging of errors and network operations can be enabled. Logs can be found at %LocalAppData%/Logs. Logs are rotated at 20 MB.
Cache Tuning
  • After deleting the last cached file in a folder the folder itself will be deleted. Parent folders will also be deleted if they in turn become empty.
  • The setting “Delete cache immediately after Upload” now allows a 0 MB value and adds a “or equal” check.
Azure
  • Added support for Azure SAS authentication including enforcement of SAS permissions.

Fixed Issues

  • Cache cleaning no longer removes pending uploads. This doesn't apply to a manual “clear” from the settings dialog, but the user is now warned in that case.
  • Fixed issue with folders not listing when containing a subfolder and object with the same name.
  • Folder enumeration using masks (e.g. DIR *.txt) is now supported. Corrects case when copying from the drive via a DOS command with incorrect case.
  • Fixed memory leaks in the drive and uploader and reduce memory consumption in general.
  • Resilience to unreliable networks has improved.
  • Uploader threads are no longer blocked when a file fails to upload 5 times.
  • The Uploader will be restarted by the Drive if it is not responding.
  • For OpenStack Swift based drives, fixed the renaming of DLOs.
  • Fixed issues opening Word documents immediately after saving.
  • Fixed an issue where in some situations files would not be uploaded.
  • Folders on OpenStack Swift storage are now created with Content-Type: application/directory to improve compatibility with Swift clients.

4.6.8

  • Connection settings allow system proxy connection settings to be overridden or ignored.
  • Improved performance for uploading small files.
  • Fixed issues that were limiting the downloading and uploading files in parallel.
  • New configuration option for number of parallel uploads (default 3).
  • Fixed DLO size edit box layout problem introduced in the previous release. (SwiftStack)

3.8.0

  • Upload progress now updates in real-time during upload of large files.
  • Allow bucket names with special and Unicode characters. (SwiftStack)
  • Improved handling of access violations. (SwiftStack)
  • Better handling of failures creating new buckets.
  • The local cache timeout period is now configurable.
  • Large files can be removed from cache immediately after upload. The file size is configurable.

3.5.0

  • Buckets are now created immediately even if a folder is empty. In earlier versions they were created when the first file was created.
  • Asynchronous operations now automatically restart after a network outage. Includes folder copy/move and upload of multi-part files.
  • Support zero-length objects.
  • Increased folder timeout from 45 sec to 90 sec (for very large containers)
  • Optimized handling of readonly and empty buckets.
  • Fixed operation handling on recently renamed folders.

  • Added support for containers containing “append blobs”. (Azure)
  • Fixed authentication issues for some recently created accounts. (Azure)

3.4.18

  • Added support for a location constraint of “EU”. (S3)
  • Connections to Amazon now use AWS Signature V4. Other providers use Signature V2.
  • Search no longer freezes with large numbers of objects.
  • More information shown for 5xx and 4xx response codes.
  • License key format has changed.

3.2.16

  • When bucket creation fails more information is shown about the reason.
  • Folders are handled (created/deleted) as objects with a trailing “/”.
