A program which grabs files, throws them together and renames them

[Previous]

You mean something that'd change a file structure like this

Code:

/folder1/sample0
/folder1/sample1
/folder1/subfolder/sample0
/folder1/subfolder/sample1
/folder2/sample0
/folder2/sample1
/folder2/subfolder/sample0
/folder2/subfolder/sample1

to something like this?

Code:

/folder1_sample0
/folder1_sample1
/folder1_subfolder_sample0
/folder1_subfolder_sample1
/folder2_sample0
/folder2_sample1
/folder2_subfolder_sample0
/folder2_subfolder_sample1

I don't know of anything that'd do it, but it shouldn't be too hard to make one.
