# Downloading data

Once data has been stored in PEP, it can be downloaded by [authorized](Access-control#data-access) users. This is commonly achieved by means of [the `pepcli pull` command](Using-pepcli#pull). In its most basic form, the command is invoked to download data for a specific participant (identifier) and column (name), e.g.:
|
|
|
|
|
|
```
|
|
|
/app/pepcli pull -p POM162733743006 -c Holter.Visit1
|
|
|
```
|
|
|
|
|
|
The `pepcli pull` puts the downloaded data into a file system structure:
|
|
|
|
|
|
- A top level directory for this download. By default the directory is named `pulled-data`, but the name and/or location can be changed by means of the `-o` switch. Within the top level directory:
|
|
|
- One subdirectory per participant, named after the participant's [local pseudonym](Pseudonymization#identifiers-in-pep). Within the participant subdirectory:
|
|
|
- One file per cell downloaded for this participant. The file is named after the column.
