Bad Peggy searches for damaged JPEG files and validates and verifies pictures for truncation and other blemishes, which sometimes occur when such files are downloaded or restored from bad backups. It's fast, easy to use, and reliable in the analysis it does. It uses all available CPU cores too.
TruPax is a tool for creating TrueCrypt volumes directly from files and folders. Volume sizes are precisely adjusted to the actual amount of data, so there is no slack. They mount on any modern OS and are of UDF 1.02 format. Creation happens quickly and directly, by creating the file system structures in the encrypted container on-the-fly. TruPax does not require TrueCrypt to be installed nor administrative rights. GUI and command line versions are available. The original material can be securely erased after a volume has been created. Volumes created by TruPax can also be extracted and all TrueCrypt volumes can be quickly invalidated.
