# Questions and Answers

|
|
## For how long will my files be stored?
|
|
|
|
Files will be removed if they have not been viewed for 30 days. A view is
|
|
counted when someone visits the file's download page (pixeldrain.com/u/somefile)
|
|
or views the file through a list the file is included in
|
|
(pixeldrain.com/l/somelist).
|
|
|
|
If you upload a file while logged into your pixeldrain account you will be able
|
|
to delete the file yourself from the download page of the file. If you are not
|
|
logged in and you accidentally upload something you shouldn't have, just don't
|
|
share the link. The file will expire eventually. File links are not indexed or
|
|
published anywhere. As long as you don't share it nobody will see it.
|
|
|
|
## Does pixeldrain cost any money?
|
|
|
|
No, pixeldrain is completely free at the moment. While there is an advertisement
|
|
on the file downloading page, it doesn't generate nearly enough revenue to pay
|
|
for maintaining this service. That's why I'd really appreciate it if you could
|
|
spare some coins. Possible methods for donating are:

## How does pixeldrain store files?
|
|
|
|
Pixeldrain uses a few different techniques to store files cheaply, efficiently
|
|
and performantly. The servers which accept files from users have a hard disk
|
|
drive cache of typically a few terabytes (4 to 16). This is where most of the
|
|
files are kept. When a file is requested from another server it will look up
|
|
where the file is stored using a lookup table in the shared database. It will
|
|
then try to contact that server to request the file and proxy the data directly
|
|
to the requesting user.
|
|
|
|
Each server keeps track of which files are popular with its own userbase. This
|
|
includes files which it is not storing locally. It does this using a popularity
|
|
score. Every time a request to read a file comes in it will add 1 to the score
|
|
of that file. This score will slowly degrade over time. Periodically the server
|
|
will request all files with a high popularity score so it can store them locally
|
|
to save bandwidth. If there is not enough space available to store these popular
|
|
files it will move some less popular files to the next storage medium to make
|
|
space available for the more popular files.
|
|
|
|
The next storage medium is Sia. This is where all the files live which are not
|
|
requested frequently, but are still occasionally needed. Sia is a storage
|
|
marketplace where anyone can sell their storage space for financial compensation
|
|
in Siacoins. If you have storage space available and would like to provide it to
|
|
pixeldrain and other services you should read our [Sia hosting
|
|
guidelines](/hosting). There we explain which requirements we are setting for
|
|
hosts and some handy tips for getting started with hosting.

## Do I need to register an account?
|
|
|
|
Not if you don't want to. You're free to use pixeldrain completely anonymously.
|
|
Without a pixeldrain account you can upload files, download files and create
|
|
lists of files. And view your uploaded files on the [history page](/history).
|
|
This page only shows files which were uploaded anonymously in this web browser.
|
|
|
|
By registering an account on pixeldrain you will be able to access your files
|
|
from any device with a web browser. Files you upload and lists you create will
|
|
be linked to your pixeldrain account and will show up on your [personal home
|
|
page](/user).
