GCSF is a virtual filesystem that allows users to mount their Google Drive account locally and interact with it as a regular disk partition. You can find out more in this paper (note: it is a draft).

Make sure you have the fuse library installed. GCSF requires the stable branch of the Rust programming language, which can be installed following the instructions on rustup.rs.

Afterwards, you can simply run:

$ cargo install gcsf

This will generate the gcsf binary in $HOME/.cargo/bin. Make sure that this directory is in your PATH variable: export PATH=$PATH:$HOME/.cargo/bin

GCSF will attempt to create a configuration file in $XDG_CONFIG_HOME/gcsf/gcsf.toml, which is usually defined as $HOME/.config/gcsf/gcsf.toml.

$ gcsf mount /mnt/gcsf
