From the included ReadMe file: Vita FTP - Developed by Coldbird - Team PRO
This is a FTP Client for the PS Vita. Launch this FTP Homebrew via a HBL (e.g. HBL r160 via Monster Hunter) and then connect with your PC Browser to the given IP, it may be this one ftp://192.168.1.5, you should be able to see the memory stick directories of your PS Vita memory card, but just the stuff inside of the PSP Emulator.
Have fun transferring files without the CMA.
1. VHBL. You must have the Vita Half-Byte Loader for one of the firmware 1.67-1.80. This works on 1.80 MHFU VHBL.
