cache - Interacting with the Local File System Cache

The chem_mat_data package can be used to download various datasets from a remote file share server. To make sure that datasets only need to be actually downloaded once, the package uses a local file system cache. Whenever a dataset is downloaded for the first time, the corresponding files are placed in the cache and if the same dataset is requested again, it is simply copied from the cache rather than downloaded from the remote server.

The cmdata command line interface provides the cache command group to interact with this cache folder:

cmdata cache --help

Viewing the Cache Content

To view all the files that are currently stored in the cache, you can use the cache list command:

cmdata cache list

This will print a list view of all the files that are currently stored in the cache directory, divided by the raw and processed dataset files.

Resetting the Cache

If you wich to reset the cache for some reason, you can use the cache clear command:

cmdata cache clear

This command will delete all the files in the cache folder.
