Error Uploading File: New File Must Be Displayable

1. Introduction

As you learn in this unit of measurement, there are multiple means of sharing resources. Creating aFolder, uploading aFile like Give-and-take document, sharing aURL to an external website, or attaching an image to the forum post are just some of the examples. Decision regarding the tool is driven past your purpose and the format of the existing resource. Moodle is a flexible system even so, as any engineering presents some constrains to the users. It is worth to know what the constrains course creator may run into when working with resources. Let'due south start with the file format then wait into other constrains.

1.1. Resource format

Commonly used learning resources comprise text, images or videos. Each of this content type can have different digital formats. It is important to evaluate what formats are more accessible to learners, through Moodle and locally installed applications. The aspects related to the resource format are:

• accessibility - is the file displayable directly in Moodle or requires an additional software? In example it requires and boosted software is information technology commercial or open up-source? Is the software popular or instructions for download and use are necessary?
• editability and formatting- is it our purpose to "lock" the content to protect its formatting? or the file should be easy to edit and absorb learners contributions?
• size - some formats, because they are compressed, aid to reduce files size.

Text

For example, PDF format every bit i of a few will be easily displayable in Moodle. In improver, PDF format reassures that formatting volition be preserved after the files is downloaded and open locally on learners PC. However, a PDF format cannot be easily edited and therefore it is not advisable for collaborative piece of work that requires input from learners.

On the other mitt most of the editable formats cannot be viewed in Moodle, therefore have to be downloaded and opened locally by each learner. The exception is Google Certificate, on which you may see more than details in another lesson of this unit of measurement: "Other tools external to Moodle". Every bit for the text files that have to be downloaded, likeMS (DOC, DOCX), or Apache OpenOffice Author (ODT),you should evaluate assess if commercial or open up-source application are more frequently used by your learners and decide appropriately. The version of the software the file is saved with is an of import aspect too.

Images and visuals

Presentation files (visuals) are often produced with the MS PowerPoint application. Even so there are alternative open-source software (eastward.1000. Open up Part Impress) or awarding for iOS (Keynote). Due to the fact that none of the visuals format can be displayed direct in Moodle, unless with a third-party plugin, any of the format is as good for Moodle. However, bare in mind that if you salve file in the most updated version of the application, it may cause issues for the users having older versions. Secondly, some applications have a cost assigned and the others are open-source, so cost free. Lastly, in the digital environment every large file means longer time for download, especially for users with slower Internet.

Images

Moodle text editor accepts JPG, PNG and GIF (too animated GIF) formats. Thus images in this format will be displayed straight in the course page. If you lot take images in other formats, they need to exist shared though File characteristic or attached in Forum mail service. In case the images take to be downloaded by learners and opened with another application, information technology is worth to think if the prototype format is easy to view and application to open it is popular. Otherwise yous may need to write boosted instructions almost how to open and preview the image.

Video

Standard installed multimedia plugins may vary depending on the Moodle version. Cheque moodle.org for the nigh updated list.

• YouTube (displays videos hosted on youtube)
• Vimeo (displays videos hosted on vimeo)
• FLV - Flash video
• F4V - Flash video
• SWF - Macromedia Flash animation File (Adobe, Inc.)

MP4 format that is the most friendly for mobile devices and so far, butIt is it's difficult to go MP4 files into Moodle merely because the nativeFlowplayer will not play MP4. The solution could be to employ a video sharing service like Vimeo first and and then embed the file together with the video thespian. Otherwise MP4 file can exist uploaded to Moodle equally File to download or attached in a Forum, too for download. In this case learners will take to have a suitable thespian (e.g. Quicktime) to playback the video. If you have multiple video to share consider using a Folder to store them neatly. Videos are normally the largest files, and that is why for learners with slower Internet, they may be challenging to download.

For how to play the animated gif that is often employ for images loops, come across Images department.

one.2. Viewing resources

Depending on the resource format and the settings you chose for the resource, it will exist either display directly in Moodle or volition accept to be downloaded by the learner and played locally.

Formats which will exist viewable directly in Moodle:

• Text: PDF
• Images: JPEG, PNG, GIF, Animated GIF
• Videos (Flowplayer): SWF, FLV
• Audio: MP3

Other formats will take to be downloaded and open outside of the Moodle environment. In that case yous should consider using formats that are commonly supported by different commercial and open-source applications.

one.3. Resource size

Maximum file size for upload or sharing depends on various settings in Moodle. The higher level of brake is set on the server. And so Moodle site administrator can adjust that figure site-wide. You may demand to contact your ambassador or It back up to understand what these limitations are for y'all. Yet, the maximum file size tin be also restricted on the single form level. If you have access to the Form Settings in the Administration panel you can check and adjust this number for your course.

Unlike activities, for example Forum or Assignment, resources accept no additional setting where the file size tin be restricted. The file size indicated in the Form Settings applies.

One thing is making sure that the form, resources or activeness settings accommodate learners needs. The other result is the server space your Moodle installation have available. This is handled past administrator, nevertheless information technology would be good for you lot to be aware what the limits are and ask Information technology personnel or administrator for guidelines. In case large files are not permitted, you may think about solutions like external repositories (eastward.g. Dropbox). External repositories help to offload some of the content and decrease space Moodle occupies on the server. Lastly large files are handled with difficulties by users with slower Cyberspace, thus yous should always keep information technology in listen when sharing resource.

1.iv. URL (links)

URL is a very flexible and powerful Moodle resource. It helps bring external resource into the course environment. Even so there are a few limitations that is worth to remember almost before calculation a URL.

Accessibility

Due to a high security protection in some institutions learners may meet a barrier when trying to access an external URL. This is true non only for individual organizations but whole countries. Our practice shows that Google products, repositories like Dropbox or video sharing services like YouTube are not accessible to everybody. The advisable solution would be to survey your learner and ask them to test URLs. In case some learners are disadvantaged, you should produce an alternative resource.

Password protected

Some websites require user to have an account. That means one ore more steps for the learner to admission the resource. Moreover, some spider web services are not free or crave agreements learners may object to.

Expired links

Nosotros have more control over the resources stored within our Moodle environment. The external URLs may expire or disappear, therefor they demand frequent review.

2. Example

There are four examples for this job demonstrating what constrains you may meet sharing unlike resources.

2.one. PDF - Class Calendar

A PDF is a adept format to brand sure that the formatting remains the same for everyone. Moreover it is a good option when y'all want to transmit data.

Furthermore, information technology is one of the formats, unlike MS PowerPoint or Earth for example, that can be viewed inside Moodle. PDF is editable only with a special commercial software, similar Adobe Acrobat Pro. And fifty-fifty if the learner has a specialised software, the editing is not an easy procedure. The same is valid for the copying of the text.

Some PDFs are more than like images or countersign protected, and text cannot be copied. That is why for re-usability reasons, PDF format is not the meant for collaborative contributions.

2.two. MSWorld - Example study template

MS Give-and-take  is an editable text file.The same is true for a MS PowerPoint  or MS Excel. Hands editable files are ideal for re-usability, peculiarly if you provide learners with a checklist, template or a worksheet so they can make full them in with their own content. For example, example studies are a often used exercises. If you would like your learners to create one of their own you can provide them with a template or a scheme to fill up in with their own case.

All the same you need to keep in heed that Microsoft products cannot exist viewed directly in Moodle, unlike PDF. That means that the file has to be downloaded and edited locally using an appropriate application. Many learners have access to the Microsoft Office parcel, but not all of them. There are open up-source software, like Open Part for case, could be an alternative for learners in case they have no access to Microsoft products.

Alternative open-source products are a expert option, however you may need to assist your learners by indicating where to download the software. If formatting is very important for you lot (tables, bullets, special headings), it is non e'er guaranteed that the output will be the same for everyone. Lastly, pay attention what version of the software you lot use for producing the file. The well-nigh updated version may be a trouble for the users who remained with the older version.

ii.3. Video - Satellite images loop

Linking to a video online elsewhere

You can share a video as link (URL) if it is stored outside Moodle or if you don't have admission to the source file. On the other manus this could be a proficient option for large files, so yous don not have to increase the maximum upload size for your course and do not risk filling up the sever space. In instance you practice not have control over the external website you take the source file from, y'all need to check frequently if the link is still valid.

Furthermore,  note thatcertain video sharing sites might exist banned, your students might not exist able to access your video through Moodle. The file format may matter as well especially in case your learners use mobile device which take some limitations. The best would exist if you lot have a chance to examination your solution with different browsers and devices.

Uploading a video for students to download

When y'all utilise File feature in Moodle, you tin set the file to exist downloaded automatically. You need to consider what format has your video. As the video will exist played locally on learners' computers, they must accept an appropriate thespian to view it. In addition, the download of the large size files may be irksome depending on the net speed available to learners.

Embedding a video with an external actor

Many of us employ video sharing services like YouTube or Vimeo. Some of the states tin have and institutional or private account bachelor on these websites. Using video sharing service to share video files have many advantages. It is easy to re-create the Embed code and insert information technology anywhere in Moodle, anywhere that the HTML text editor ( TinyMCE) is available. The embed code consist of a player, which should make the video accessible independently from the browser and plugins locally available to the leaner.

Embedding a video in its own player

Moodle has an inbuilt video player chosen Flowplayer. If the multimedia plugins filter is enabled by the administrator, videos embedded into the text editor will play inline in Flowplayer.  Again anywhere that the HTML  text  editor ( TinyMCE) is available, it is possible to embed a video, for example in a label or a page, a form topic summary, or a lesson.

1 ecxeption seems to be MP4 files. They don't seem to play in Flowplayer.

two.4. Stand up-lone website (File/URL) - COMET lesson or Simulator

one. COMET lesson -embedded File

Reusing fix resources saves fourth dimension. Withal many resources are a) to broad and b) have its own navigation.

Ideally we will observe time and tools to retrieve only a chunk of content that we really need from a broader lesson or module. Otherwise we need to point the learner and inform what part of the content is required from him to view.

Resources, similar COMET lessons, accept their own navigation as well as the course website. The double navigation may exist confusing for learners. In addition, links included in the resource may lead to external website or external resources. It is good to exist articulate about what is the essential and what optional role.

File feature is one of the solutions to upload a stand up-lone website to and have information technology run in the form surround. For details encounter the lesson on "Displaying resource - Appearance".

two. Simulator - URL or a File to download

Simulators are becoming more and more popular in our training. Similar any interactive exercise they may be large files. Storing a simulator in an external repository may be necessary due to the space it occupies on the server. Appropriately a simulator would exist shared equally an URL pointing to the external repository. Nevertheless, you should keep in listen that there will exist two carve up spaces to go on up-to-date -- Moodle form and external repository.

Another manner of sharing a simulator, which volition reassure that the learners have the file saved locally is to using File with a Force download setting.

3. Educational activity

This lesson covers topics that intertwine with many other lessons in this units. That is why for detail instructions you take to browse other lessons.

For instructions regarding

• Uploading files (text, video, images) check "Using File Picker" lesson.
• Embedding video check "Embedding resources" lesson.
• Setting a stand-lone website bank check "Displaying resources" lesson.

Increase maximum file size for the form

When setting up a new grade yous can exit the default maximum size or customize it according to your needs. The Maximum upload size setting defines the largest size of file that can be uploaded by students in this form. To change it

ane. In the Administration block become to Edit settings.

2. In the Files and uploads section > Maximum upload size select a file size from the drop down menu.

Note that the site administrator can determine sizes available for the instructor to select. That is why you will see limited choices to select. Editing teachers or other users may be immune to upload files larger than the maximum size by giving them the capability moodle/form:ignorefilesizelimits. You demand to ask your administrator for this capability if necessary. It is possible to farther restrict this size through settings within each activeness simply not resource. When uploading big files, consider that your students volition need to download them to view them.
