Free Space Analyzer

What the App Does

• Scans all PS Vita storage partitions:

  • ux0: → Main memory card / SD2Vita

  • uma0: → Secondary storage (SD2Vita, USB, etc.)

  • ur0: → Internal system storage (where plugins usually live)

  • imc0: → Internal memory (only on some Vita models)

• Calculates storage usage:

  • Total size

  • Used space

  • Free space

• Displays results graphically:

  • Colored bars (like progress bars) to show usage percentage.

  • Numeric values in MB/GB.

• Navigation:

  • Switch between partitions with D-PAD.

  • Press ✕ (cross) to exit.

Extra Features

• “Top space consumers”: shows the heaviest files and folders in the root of the selected partition, so you can quickly see what takes the most space.

• Battery info: displays charge percentage and charging status.

• FPS counter: shows rendering performance.

 In short: it’s a disk usage analyzer for PS Vita (similar to tools like WinDirStat on PC), helping you free space and better understand where your storage is going.

Free Space Analyzer – Changelog v1.03

•  New Features

Smooth FPS Display: Replaced the fixed 59 FPS with a real-time FPS counter using an exponential smoothing filter for a stable and natural update, similar to in-game FPS behavior.

Overlay Filters Panel: Animation direction updated; the filter overlay now slides in from the right to left when activated.

ASCII Confirm Key: Updated command instructions to display the confirm button as “X” in ASCII instead of the symbol.

•  Improvements

Refactored FPS Calculation: Replaced local variables with global variables (g_last_time and g_fps_real) to avoid compilation errors and ensure correct tracking across frames.

Improved Overlay Animation: Smooth transition with configurable speed; overlay panel no longer jumps abruptly.

Command Menu & Buttons Optimized: Command instructions and key assignments have been refined for better readability and usability.

Code Cleanup: Removed hardcoded FPS values, ensured proper initialization of timing variables in ui_init().

•  Bug Fixes

Fixed compilation errors related to undeclared variables (last_time and fps_real).

Corrected overlay filter positioning to prevent graphical glitches.

Ensured “Calculating…” overlay renders correctly under all conditions.

•  Notes

FPS is now reported in real-time, smoothed for readability.

Overlay panel animation and folder highlight behavior have been tested on PS Vita hardware.

Free Space Analyzer – Changelog v1.02

New Features

• Added battery status indicator with dynamic color based on charge level (green, yellow, red).

• Added FPS counter to monitor performance in real time.

• Added program name label displayed at the top of the screen.

Improvements

• Free Space Analyzer now shows "Free space" label next to Battery at the top, as requested.

• UI design updated to avoid text overlap with button hints and other on-screen elements.

• Optimized GPU usage to prevent crashes when battery and FPS counters are enabled.

• Free Space Analyzer screen no longer auto-closes; it now requires manual exit with ✕.

Fixes

• Fixed bug where holding ✕ in Free Space Analyzer caused unintended behavior.

• Corrected initialization of vita2d_get_fps() and related rendering functions.

• Fixed missing or implicit function declarations (sceIoDevctl, vita2d_draw_texture_blend, etc.).

• Improved back navigation in Advanced Settings (properly returns to the main menu).

v1.01 (Current Update – Extended Features)

Planned Features (Future Ideas)

• File type color coding in the UI (games in blue, music in green, etc.).

• Additional filters (Videos, Archives).

• Export report to text file (ux0:/data/fs_report.txt).

• Sorting modes (by size, name, type).

• Storage usage pie chart (per category).
