Question about installing modules

It is not that simple in a shared hosting environment such as Backendless Cloud. It opens up possible holes for malicious use such as over filling the disk space with junk and impairing overall service stability.

Doesn’t the usage limit and access rules and restrictions work with it?

is there any possibility to make this work in any way even with limits to few file extensions and file size?

its really not practical to pay for a another server other than backendless just to generate the file then upload it to my files in backendless

The usage can be checked when data flows through our APIs, if the file system is accessed directly, it becomes a significantly harder problem to enforce it in a shared hosting environment.
