A folder must be on NTFS to be encrypted using EFS.
The requirement is to at LEAST encrypt all sensitive and unclassified information not cleared for public release that is stored on removable and mobile computing devices. That may very well mean that the entire media must be encrypted, but there are acceptable solutions that only a portion of the storage media - as an encrypted file or encrypted partition. It is important to select a truly effective encryption solution however. If the keys to decrypt the information are stored on the same device, it isn't going to provide much protection. Likewise, if it is easy to break the encryption it isn't going to help much. If temporary files store the information in unencrypted form, then again it isn't really protected. Once encrypted, the decryption key(s) need to be protected and maintained such that an authorized user can still access the data. If you lose the key and have no backup, you have just caused a self-initiated Denial-of-Service.
Any device which contains data not approved for public release and is portable is subject to the DoD "Data at Rest" policy. The stored data must be encrypted on: Laptop computers Notebooks Cell phones BlackBerrys, Treos, Palm Pilots, smart phones and other functionally similar devices PDAs External hard drives CDs DVDs Floppy Disks (yeah - some people still use them) Thumb drives Flash cards Any other removable media For more details, Google the phrase "DoD data at rest" and check out some of the links to find the memo that details the requirements. I'd post the address of some good sites, but that would get this post flagged.

Removable storage is a very helpful thing if you don't want to deal with emailing attachments. Flash drives are getting cheaper, more reliable, smaller, and higher capacity. Although you must be careful to back up documents because the physical device can get lost, stolen, or smashed. Make sure you keep hard copies and/or digital copies on a hard drive.
Classified information can be stored in secure facilities known as Sensitive Compartmented Information Facilities (SCIFs), which are designed to protect sensitive data. It can also be kept on encrypted digital storage devices, secure servers, or classified networks that have restricted access. Additionally, physical documents may be stored in locked safes or vaults that meet specific security standards. All storage methods must comply with relevant regulations and guidelines to ensure the protection of the information.
While most embedded systems computers are not equipped with secondary storage, there are some that do have secondary storage. Such secondary storage when present is usually some kind of nonremovable Flash drive (although sometimes the Flash drive is removable, e.g. SDHC card). The reason most embedded systems computers are not equipped with secondary storage is that the application code is relatively small and no updates are expected to be needed, also the size of RAM is predetermined and the program must run in realtime so the use of virtual memory on disk is not desirable as it can produce unpredictable delays resulting in missing of realtime deadlines.

To ensure storage devices remain functional, keep them in a stable environment with controlled temperature and humidity levels, as extreme conditions can lead to damage. Regularly back up data to prevent loss in case of failure, and handle devices carefully to avoid physical shocks. Additionally, use antivirus software to protect against malware and perform periodic checks to monitor the health of the devices.
