Failed to scan c: not enough storage is available to process this command

Hello, I'm Benigmatica and this is my first time using Recuva. I tried using Deep Scan to recover my pictures from my main disk drive, but it seems that I got an error message that "there's not enough storage available" or sometimes close the program unexpectedly. Here are my PC specs:

Processor: Inter® Core2 Quad CPU Q8300 @ 2.50 GHz
Installed RAM: 4 GB (3.5 GB usable)
System Type: 32-bit
Disk Drive Space: 465 GB
In any case, can anyone help me and if this problem can't be solved, what are my options?
Anyways, thank you!
