Memories supports the file types supported by the Nextcloud previews app. If you add support for any one of the file types below, you must run `occ memories:index` to index these files.
## Common Formats
```
PNG (image/png)
JPEG (image/jpeg)
PNG (image/png)
GIF (image/gif)
BMP (image/bmp)
```
These are enabled by having the following in your `config.php`,
```php
'enabledPreviewProviders' =>
array (
'OC\\Preview\\Image',
),
```
## HEIC and TIFF
You must enable `HEIC` and `TIFF` in Nextcloud `config.php`, and install Imagemagick (included in the official Nextcloud docker image)
In `config.php`, add,
```php
'enabledPreviewProviders' =>
array (
'OC\\Preview\\HEIC',
'OC\\Preview\\TIFF',
),
```
## Videos
You need to install `ffmpeg` and add the video config to `config.php`
```php
'enabledPreviewProviders' =>
array (
'OC\\Preview\\Movie',
'OC\\Preview\\MKV',
'OC\\Preview\\MP4',
'OC\\Preview\\AVI',
),
```
