Help:Multiple uploads

Instead of uploading files one-by-one, it's possible to upload multiple images at once. Administrators may upload up to 20 images simultaneously, while non-admins have a limit of 10 images.

Any choices made for licensing templates, categories, or descriptive text apply to all images that are being uploaded. If you're uploading many images that should have the same license and categories, it can be a huge time-saver.

How to use it?
Go to Special:MultipleUpload on your community. Click the Choose File buttons to find the files on your computer and, if you want them to have a different name to the one they have on your computer, change these in the "Destination filename" fields. Then, fill in the summary and select a license, both of which will be applied to the entire batch of images.

If a file has the same name as another that is already on the wiki, you will see a warning similar to the one that appears for individual uploads, but the file that already exists can be replaced.

Limitations
When using Special:MultipleUpload, the file upload size limit limits the total size of all the files combined rather than the size per individual file. The current limit is 10 MB for all of the files uploaded together, which makes multiple uploads great for quickly getting many small files into the wiki, but not ideal for large ones.

Admin notes

 * Admins can change the text at the top of the multiple upload special page using the system message MediaWiki:Uploadtext.
 * This functionality comes from the MultipleUpload extension.

Alternatives on UCP
While this extension is not available on the UCP, there are still ways to upload multiple files at once. However, these methods do not allow users to select a license for the files.

MsUpload
MsUpload is an upload tool built into the source editor. It has an upload button that will open your file browser, from which you can select multiple files by holding the control key on your keyboard. Alternatively, there is a box below the editing toolbar where you can drag-and-drop a selection of files from another window. Selected files will be displayed as a list of tiles. Below this list should be two buttons; one to upload the files and another to clear the list.

To remove an individual file from the list, click the "X" icon on the right of the corresponding tile. To rename a file before it is uploaded, click the file's name to activate the text field. Then type the desired name and press the enter key on your keyboard to deactivate the text field. If a selected file shares a name with a file that has already been uploaded to the wiki, it will be added to the list with a warning message displayed in the tile. The file will not be included in the upload until either the name is changed or you check the checkbox indicating that the file should be uploaded anyways.

If you use MsUpload while editing a category page, by default, all images uploaded will be automatically added to that category. Near the right side of each tile, there will be a checkbox and the name of the category. You can uncheck the checkbox to avoid adding the file to the category.

MultiUploadBar
MultiUploadBar is an upload tool built into the VisualEditor (both visual mode and source mode) and it functions very similarly to MsUpload. The icon used for MultiUploadBar is similar to the icon used for MsUpload and the button is available in addition to the media button used to insert single files and files that have already been uploaded to the wiki. Unlike MsUpload, the drag-and-drop box is not always displayed. The button displays the drag-and-drop box which contains an additional button to upload files using your file browser. Below the selected files list are three buttons; one to upload the files, one to clear the list, and another to insert the files onto the page after they have been uploaded.

The "X" icon to remove an individual file is located on the left of the tile. The text field for renaming a file is activated by clicking anywhere on the tile and deactivated by clicking anywhere off the tile. There is no warning for selected files that share a name with files already uploaded to the wiki.

Like MsUpload, if MultiUploadBar is used while editing a category page, the files will be added to that category by default. Also similar to MsUpload, this can be avoided by unchecking the checkbox next to the category's name for each file that should not be added to the category.
