Available file formats for uploading
You can only enable certain file formats to be uploaded to the system:
- Enable the Available file formats option and click Save.
- Set the list of available formats. To do this, click +Add format and fill in the fields in the opened window:
- File format. Enter the extension that will be available for uploading.
- First 8 bytes. Specify up to 8 bytes of the file format signature. Signatures are constant values for each file extension. For example, for the .png format, the signature is 89 50 4E 47 0D 0A 1A 0A, and for a text file in UTF-8 BOM format, the signature is EF BB BF. A list of signatures is available on Wikipedia or on specialized sites such as Asecuritysite.com.
