# Genotype Files in Sandbox

FinnGen updates genotype data in each [Data Release](/finngen-data-specifics/finngen-data-freezes-and-releases.md) and makes these files available to Sandbox users.

### Sandbox directory

Since Data Release 4 genotype data is available in the following sandbox directory:

`/finngen/library-red/finngen_R[RELEASE]`

The genotype data of releases 1-3 can be found from:

`/finngen/library-red/finngen_R[RELEASE]_core_analysis_results`

### Data files

The data files are described in the following sections:

[Imputed genotypes in VCF format](/finngen-data-specifics/red-library-data-individual-level-data/genotype-data/types-of-genotype-files-available/imputation-data-file.md)

[Imputed genotypes in BGEN format](/finngen-data-specifics/red-library-data-individual-level-data/genotype-data/types-of-genotype-files-available/bgen-file.md)
