server also allows for non-agents to upload packages, as long as they have the

## Directory Structure
|
||||
|
||||
The data directory consists of three main directories:
|
||||
|
||||
* `downloads` - This is where packages are initially downloaded. Because vieter moves files from this folder to the `pkgs` folder, these two folders should best be on the same drive
|
||||
* `pkgs` - This is where approved package files are stored.
|
||||
* `repos` - Each repository gets a subfolder here. The subfolder contains the uncompressed contents of the db file.
|
||||
* Each repo subdirectory contains the compressed db & files archive for the repository, alongside a directory called `files` which contains the uncompressed contents.
