overwritten file recovery

[yuer]

Hi, Everybody,

I have a very very important file deleted from USB by accident. And the USB drive has been stored other big files after the accident. I tried to recovery the file i deleted, but that file was not recovered. Probably, it has been overwritten. Does any body know if there is a software which can recover overwritten files? Desperately need your help.

any comments will be greatly appreciated.

please, could anybody help me. Maybe this is a stupid question. Maybe there is no software which can recover overwritten file. I know here there are experts on computers. I am not good at computer. That's why i made a stupid mistake. I just want to know if it is true that there is no such a software.

Desperately need your kind help.

what recovery software did you use when you tried to recover on your own?

If the file was really over written, then you can't get it back...

There can be a slight chance that some portions of the file are in Flash blocks currently not used by mapping the flash to LBA space.
This has some probability, bellow 1% I think.
to find those blocks someone has to read out entire flash content and check the used/unused blocks.
Time consuming process for less than 1%...
