I present to you my 'Pico Navigatto'. A File Manager in MMBasic for PicoMite.

I have tested it on PicoCalc and on my PicoMite RP2350 VGA.

Please make a backup before you start testing it.

Features:
----------------
Maximum of 300 files.
Maximum filename length: 105 characters.
Maximum extension length: 12 characters. Although only 3 are displayed.

If any of these specifications are not met, the program will crash.

In this case, you can try changing the initial parameters. You can try lowering the number of files and increasing the filename length, or vice versa.

Keyboards:
----------
Up/Down Arrow: Moves up and down in the table.
Left/Right Arrow + Tab: Changes columns.
Up/Down Arrow + Shift: Page Up/Page Down.
Home/End: Start/End of column.
Space: Selects/Deselects an item.
A/B: Selects the column unit.
Enter: Enters the directory/Executes BAS/Displays BMP.
Backspace: Exits the current directory.
C: Copies a file or a selection of files.
R: Renames a single file or directory.
D: Deletes a file/directory or a selection of them.
K: Creates a directory.
Z: Displays the size of the file, directory, or selection.
S: Changes the Screen font.
Q: Exits the program immediately.
H: Displays a brief help message.

Comments:
---------
The bottom line of the screen displays: Size, date, and time, or whatever fits.

I tried to make it display more or less information depending on the number of characters on the screen. But when I added the date and time fields, the program became too slow.
This is my fault because the program reads from the disk very frequently to update itself.
The same thing happens when the number of files increases considerably. I have a folder with more than 100 files, and it's starting to become very noticeable.

I appreciate comments and suggestions, and please don't be too critical.

I apologize for the bugs you're sure to encounter.

Best regards.

A really nice file manager. Runs flawlessly on my PicoCalc. I’ve placed it in drive A: and assigned it to the F1 function key. That way, it’s always right at your fingertips. The different text sizes are also great. It would be even better if it included a .txt viewer and an MP3/WAV player. Well done!
