FileOptimizer is a broad format file compression tool used to reduce file size without changing the quality, known as "lossless." This is done via wide variety of optimization and recompression tools and techniques. Original files are sent to the recycle bin for restoration in the event the uncompressed version is preferred.

Supports drag-and-drop of files into the window or onto the program icon. Note that by default the program removes metadata for many file types. This information reduces overall file size and protects privacy but is important to some users (e.g. photographers) and file search tools.

A 64-bit version is available within the folder, the author reports the program is functional in WINE, and can be used on the command line. Many images here on TPFC including our logo have been compressed using FileOptimizer.

gpg4usb is a basic, tabbed notepad tool with easy-to-use text and file encryption tools. Using the Gnu Privacy Guard (GPG) security system means you can exchange encrypted text and files with someone you've never met, where most programs require a communicated password. Additionally, users can digitally "sign" and verify information to help establish integrity, ownership, or agreement.

Users need only exchange a "public key" with one another in order to communicate. New users will need to generate a key, while users of other compatible software can import their existing keys.

Functional in Linux (see How to Extract). GPG is a compatible, open source alternative to the former commercial corporation PGP.

VaultPad is a simple text and file encryptor. The program can take text, attachments, or both to create an easy-to-share XML file for storage or sharing.

The program uses AES cipher (symmetric-key pairs) to encrypt local messages and RSA/AES cipher (public/private key pairs) for shared messages. A SHA-512 cipher is used to hash passwords, so they aren't stored in the application itself. A MD5 algorithm is used to check embedded files for corruption. VaultPad will handle third party public keys to be able to encrypt/decrypt their files directly.
