# Testing Files and Attachments This test contains instructions for the core team to manually test common attachment types. All files for testing are stored in the [mm_file_testing](https://drive.google.com/drive/folders/0B9-SWBTtyOCBRlEyaW1IdkZ4X1k) Drive folder. Follow these instructions: 1. Download the entire [mm_file_testing](https://drive.google.com/drive/folders/0B9-SWBTtyOCBRlEyaW1IdkZ4X1k) folder. 2. Drag and drop each file type into Mattermost to upload it (upload some as multiple attachments on the same post) 3. Post the file attachment **Notes:** - All file types should upload and post. - Read the expected for details on the behavior of the thumbnail and preview window. - The expected behavior of video and audio formats depends on the operating system, browser and plugins. View the permalinks to the Public Test Channel on Pre-Release Core to see the expected cases. - If the browser can play the media file, media player controls should appear. If the browser cannot play the file, it should appear as a regular attachment without the media controls. ### Images **JPG** `Images/JPG.jpg` Expected: Scaled thumbnail & preview window [Permalink](https://pre-release.mattermost.com/core/pl/bgx3wcd9ppdo7fz9zqokofg7sc) **PNG** `Images/PNG.png` Expected: Scaled thumbnail & preview window [Permalink](https://pre-release.mattermost.com/core/pl/zra4yhm69j8ij81iy5hw7983qe) **BMP** `Images/BMP.bmp` Expected: Scaled thumbnail & preview window [Permalink](https://pre-release.mattermost.com/core/pl/1hx7x7t1npn4jqyr5rb1qhbj3h) **GIF** `Images/GIF.gif` Expected: Scaled thumbnail & preview window.
