# file

File filter is used to manage your files. This might be useful if you need to upload a file to an FTP, share file url with another system, or accept files submitted by the users through the forms.

{% hint style="info" %}
Deprecated. Use [storage\_read](/liquid/tags/storage_read.md) and [storage\_write](/liquid/tags/storage_write.md) instead
{% endhint %}

Each installation comes with a storage. The amount of storage available depends from the plan you are on.

* Trial - 5mb
* Basic - 20mb
* Advanced - 50mb
* Pro - 100mb

{% hint style="info" %}
Files are stored only temporarily and after 48h are automatically deleted.
{% endhint %}

You can save your files based on following sources:

* content - string captured with `capture` tags
* multipart - file coming from a user form submission
* url - publicly accessible file hosted under specified url

Not all files can be uploaded to your storage. Currently storage is configured to accept following files:

```
jpg,
png,
gif,
txt,
log,
mp4,
csv,
tsv,
pdf
```

File extension needs to be specified in fileName parameter when uploading.
