Our Large File Sending service (called Cloudstor) is provided by AARNet. Cloudstor provides you with a secure way to share large files with anyone. Files can be accessed by recipients from anywhere they have an Internet connection.
Once the file is uploaded each recipient is emailed a link so they can download it. The file remains available for 20 days.
When a recipient downloads the file an email notification is sent to you (as the sender) and to the recipient.
This service can also be used by non CSU staff to send you a file. You can grant them access by creating and sending them a Guest Voucher.
The Large File Sending service provides a quick and easy solution for all of the following problems
The file you need to share
The file an external colleague needs to share with you
Benefits of using Large File Sending service include
If internal access is all that is required the file should not be sent using this service but instead saved to the S: drive. Staff can then use the Windows Explorer address bar to copy and paste the files location into an email and send it to other CSU staff. Remember to ensure the S: drive location can be accessed by all staff that the link is sent to. If it isn't you will need to discuss the access requirements with your Share Administrator or save it in the Common folder where there are no staff access restrictions.
Any type of file can be uploaded with the proviso that it does not breach the Use of University Computing and Communications Facilities Policy.
The size of the file you can upload depends on the browser and version you are using. HTML 5 compatible browsers enable you to upload a maximum of 100 GB whereas non HTML 5 compatible browsers only provide the ability for up to 2 GB.
Non HTML 5 browsers require a minimum version of Adobe Flash Player 10. You can find out which version of Flash Player you have by visiting the version check page. If you are using a CSU owned Windows based computer you can upgrade by going to Install Software.
Internet Explorer, Firefox, Chrome and Safari are available for installation on all CSU Windows and MAC computers.
|Browser version||Detected as HTML 5 compatible browser||Maximum file size upload||Resume interrupted or cancelled uploads|
|Internet Explorer 11||Yes||100 GB||Yes|
|Firefox 22.0 and above||Yes||100 GB||Yes|
|Chrome 28.0 and above||Yes||100 GB||Yes|
|Safari 6.03 and above||Yes||100 GB||Yes|
You can only send one file at a time. If you have multiple files to send you can use 7-Zip to do this. See sending multiple files below for more information.
You can send a file to a maximum of 100 recipients at a time.
If you need to send to more than one email address you must ensure you separate each address with a semicolon e.g. firstname.lastname@example.org ; person2@Australianuniversityname.edu.au ; email@example.com
An email will be sent to the recipient with a link to use the voucher.
If you are using a HTML 5 compatible browser you can resume your upload by sending it again. The file must have the same name as before for Cloudstor to recognise it. When the upload starts again the progress bar will jump to where the uploaded was halted previously and continue from there.
Yes. If you have more than one file to share with the same recipients you can put them all in one folder, zip the folder and then send it as one file.
Zipping is a term used to describe the process of compressing (reducing) the size of a file. Smaller files take less time to send and download and take up less storage space on a computer. Zipping can also be used to put multiple files inside of one file. A zip file can be easily recognised because it's file extension is zip. A file extension refers to the characters after the dot at the end of a filename e.g. myfile.zip. The file extension is how the computer determines what program should be used to open the file.
Zipping is also known as archiving, it is important to be aware of both terms as they refer to the same thing.
The ability to zip and unzip files is built into Windows and MAC (OS X and above). There is also software available that can provide higher compression resulting in smaller file sizes. Some examples include 7-Zip, WinZip and WinRAR.
The built in Windows zipping software and 7-Zip uses this icon to represent zip files WinZip uses this icon and WinRAR uses this one . File compression tools can be downloaded from Ninite
Once a file compression tool is installed you can quickly and easily zip files using the right click menu.
To zip a file using 7-Zip:
The name of the file you have selected will appear between the quotes. In the example below the file is called File to compress.
The first time you zip a file from inside of the program you will need to change the archive format setting from .7z to zip.
The first step is to place all of the files you need to send into one folder, once you have done this you are ready to zip the folder.

Yes - when using special file compression/archiving software, you need to be aware of this. It is important to know what kind of files your specific file compression software can open and what it's default settings are for compressing files. e.g. 7-Zip has it's own file type of .7z so if you compress a file without changing the archive format setting to zip you will end up with a .7z file (e.g. myfile.7z instead of myfile.zip) Those without additional file compression software such as WinZip, WinRAR or 7-Zip will be unable to open that file unless they install one of the abovementioned programs. This problem can be avoided by always using zip files as Windows and Mac can open them without the need for additional software making them accessible to everyone.
The good news is that most file compression programs integrate with Windows once installed meaning you don't have to worry about changing settings if you don't require the additional features provided by opening up the program. You can just right click on the file/folder and select the zip option.
Yes you can password protect your file but you must do it before you send it. All common file compression tools have the ability to set a password. The most common file compression tools are WinZip, WinRAR and 7-Zip.
7-Zip is available for installation on your CSU computer from the Install Software icon, by default 7-Zip uses it's own file format for zipping which is .7z you should change this to zip the first time you use it.
You will need to select a different option which will open 7-Zip and allow you to specify a password which recipients must enter to open the file. The first time you zip a file from inside of the program you will need to change the archive format setting from .7z to zip. When specifying a password you can choose to show the characters so you can see the password you have entered and ensure it is correct or you can enter it twice and it will only be shown as stars.
To password protect a file or folder:
When password protecting a file remember to provide the password to recipients. Recipients will be unable to open the file inside the zip file unless they have the password, file compression tools will open the zip file and show the file inside but when they try to extract it or open it they will be prompted for the password and won't be able to get any further without the password.
