Depending on the size of the directory and number of files you want to compress, you can perform the compressing via an [Interactive Job]({{< relref "creating_an_interactive_job" >}}) or [SLURM job]({{< relref "submitting_jobs" >}}).

#### Can HCC provide training for my group?
 
HCC can provide an introductory training (up to 2 hours) for groups on request via Zoom and In-Person.
 
 
Before submitting a request for training, please ensure everyone who will be attending has an active HCC account **and** has activated DUO for their HCC account.
 
 
Training requests can be submitted to {{< icon name="envelope" >}}[hcc-support@unl.edu](mailto:hcc-support@unl.edu).
 
Please include:
 
 
- A list of available times
 
- How many will be attending
 
- Preference on Zoom or on-site training
 
- If on-site, what location is it at?
 
 
An HCC staff member will reach out to confirm the date and location.
 
 
HCC also provides virtual Open Office Hours every Tuesday and Thursday from 2-3 PM. More details are available on the [Office Hours webpage](https://hcc.unl.edu/OOH).
 
 
#### Can HCC provide help and resources for my workshop?
 
We are happy to help with your workshop! We are able to provide up to 40 demo accounts for participants who don't already have HCC accounts and can have a staff member on-site to provide assistance with issues related to HCC and answering HCC related questions.
 
 
Please submit your request atleast **1 month in advance**. Requests may not be able to be fulfilled based on staff availability. It is strongly recommended to involve HCC staff during the initial planning of the hands-on portion of the workshop in order to provide smooth and timely experience with HCC resources.
 
 
Before submitting a request for workshop support, please fully test your materials using Swan and provide us a complete list of any software packages and environments that are needed.
 
 
Workshop support requests can be submitted to {{< icon name="envelope" >}}[hcc-support@unl.edu](mailto:hcc-support@unl.edu).
 
Please include:
 
 
- The date(s) and time(s) HCC will be utilized during the workshop, including any neccessarry setup.
 
- How many will be attending. If possible, please provide how many already have HCC accounts.
 
- Location of the workshop
 
- A list of software packages or environments that everyone would need.
 
- If you are using Open OnDemand JupterLab or RStudio, we can create custom kernel/image for the purpose of the workshop.
 
- If you are using a conda environment, we can create a shared environment for participants to use without the need to have participants creating their own.
 
 
 
An HCC staff member will reach out to confirm the date and location.
 
 
#### Where can I get training on using HCC resources?
 
HCC provides free and low cost training events throughout the year. Most events are held in-person, but some will be hybrid or Zoom.
 
 
New events are posted on our [upcoming events page](https://hcc.unl.edu/upcoming-events) and announced through our [hcc-announce mailing list](https://hcc.unl.edu/subscribe-mailing-list).
 
 
Past events and their materials are also available on our [past events page](https://hcc.unl.edu/past-events).
