Allowing new file extensions other than the default attachment types e.g. zip, eps, etc.

I believe for the new Media module that uses file entities, you need to update the MIME list here: admin/structure/file-types/manage/document/edit

Does this still occur?

Aptalops - please could you try this in order to upload a zip file (as it worked for me)?

Admin>Structure>File types>Add file type
Field 1: Zip
Field 2: zip files
Field 3: application/zip
Save

Thanks and good luck.

Kudos to Open Atrium developers and product.

If this helps, navigating to admin/structure/types/manage/oa-wiki-page/fields/field_oa_media and entering an additional file extension in the list of "Allowed file extensions for uploaded files" allowed an upload of the new extension.

I had to be able to upload a powerpoint .pptx file type to a document page and I followed the steps in post #11 and added pptx to the Allowed file extensions for uploaded files values and this worked.

OK, closing then. No activity and this seems to work for most people. @Aptalops: please reopen as a support question if needed.

I just ran across a special case so thought that I'd it here in case it helps others.

Occasionally you might want to add a file type that is not included in the mime filetypes, such as an 'ini' file, or perhaps a file type extension that is internal and so not publicly recognized.

In this case we have the same problem (where it needs to be added) but also a new problem where the mimetype doesn't appear in the list of available mimetypes and so files ending 'ini' cannot be added.

For me the solution was to edit openatrium/includes/file.mimetypes.inc and add 2 new rows, one to each array. In my case:
Added to first array (called mimetypes):
1000 => 'text/ini',
Added to second array (called extensions):
'ini' => 1000,

Now I could add the 'text/ini' file type as in Step 10, Field 3 above and so upload 'ini' file types to my open atrium installation .

Hi,

just to add here for others:

I was looking for a way to add an .eps file as attachment.
In the default includes/file.mimetypes.inc I found that the eps extension is linked to "22 => 'application/postscript',"

So just add "application/postscript" in the mimetypes list at "admin/structure/file-types/manage/document/edit" and you can add as .eps file as Document!

To pass the first Media-browser upload button, you should also add .eps to the allowed file extension at "admin/config/media/file-settings"

Thanks bigals #14 worked for me - added in ability to load microsoft email messages (application/vnd.ms-outlook msg) - following those instructions followed by clearing cache enabled this filetype to be added.

These steps help with adding the mimetype,
Admin>Structure>File types>Add file type
Field 1: Zip
Field 2: zip files
Field 3: application/zip
Save

But after that I had to also add 'zip' (without the comma or dot) to the list of accepted file extensions to "Default allowed file extensions"

Updated with rschaeffler notes for ease of finding the complete solution rather than parsing the entire thread.

I am clearing the content of the files added by the spammer.

(It seems the files aren't cleared if I don't submit a new comment, after I am redirected to the comment create form.)

For me in Drupal 8, in addition to the steps outlined in comment #15 above (adding application/postscript to the mimetype list) there was an additional step of adding eps (or zip) as an acceptable file type for the entity browser. Instructions:

1. Go here: admin/config/content/entity_browser
2. Click the edit button for the entity browser of your choice.
3. Click next button five times or until you reach a page with a table including an "Operations" column.
4. In the operations column you should see a "Allowed file extensions" field. Add "eps" (no comma or period) to the end of this list.
5. Click the next button to save your changes.

Repeat these steps as needed for other entity browsers in the list.
