TeraCLOUD implements a WebDAV engine (high-speed WebDAV) that has been reformed specifically for TeraCLOUD purposes and use. These improvements have been in accordance with the high-speed and versatile "Apache mod_dav."
*We do not accept inquiries about WebDAV compatible apps.
- Depending on the user's software, compatibility issues with applications are common for the WebDAV protocol. At times connective issues and the inability to download or upload files might occur.
- Contingent on applications of use, meta-information (information for applications to judge the situation) is saved in a designated folder. The handling of these folders may cause compatibility issues.
- Due to OS and apps handling of labeling files being different, original file labels may be jumbled.
- This information can be found in "What kind of storage does the data store?" After the use and understanding of WebDAV connection, all files uploaded to TeraCLOUD must be different.
About high-speed WebDAV
- Although there is no restriction on the upload/download file size, it is recommended for users to try to keep it below 2 GB for safety.
- There may be restrictions depending on the apps.
- If applications are compatible with partial content upload (depending on the software, resume upload may contain meaning), it is recommended to keep it at roughly 16 MB.
- High-speed WebDAV is not available on the user's cloud.
About WebDAV apps that may not be recommended or may not be available
For WebDAV apps such as the following, it may not be possible to use normally.
Mounting as a file system
- Windows Explorer (OS standard WebDAV connection · Network drive function etc.)
- Mac OS X webdav (OS standard WebDAV connection · "Connect to server" function in Finder or mount with "mount_webdav" command at terminal)
- Linux davfs / davfs 2
Broadly, volumes mounted as a file system are devices with fast reaction speeds. As a result, applications accessing that volume are built on the assumption that reaction speed is fast.
By way of illustration, Windows explorer, Mac OS X Finder, and Nautilus on Linux Gnome can all see file information, check directory information before opening the file, and create thumbnails and process the files prior to being accessed by the user.
Lamentably, the response speed of TeraCLOUD's WebDAV service exists on the internet and is shared by a significant number of users as it is shared. Accordingly, the response speed is regrettably slow compared to these local devices. The rate of these local devices can exceed 1,000 times. Due to this, applications that frequently access detailed data often acquire data repeatedly, which can be exceedingly plentiful and may exceed the timeout time of the file browser (Explorer, Finder, Nautilus, etc.).
Furthermore, even if there is disruption due to the influence of the network or service, we will not perform a retry to resume. Although TeraCLOUD will continue to improve its speed in the future, considering the delay of the internet, it is unfortunately unbearable, and it will be impossible to complete file uploading and downloading.
That being the case, it is recommended to use WebDAV apps on Windows, Mac OS X, or Linux.
Other compatibility issues
- Different handling of file names
- Subtle differences in file transfer method
Further descriptions and issues will be added upon discovery.
