Hello everybody,
So I have thousands of text files, with the names like "textABC05_023.tab"
I want to check if one of these files exists. So I use the following:
result = file_test('Documents/DataFile/textABC05_023.tab') & print, result
The problem is, this only works if I know the exact full name of the file. What if I only want to check the existence of files, given that I know only part of the name, like "textABC05" (omitting the "_023" part)?
Part of the reasons I want to do that is these files have really random numbers at the end, and all I care is whether their names match up to the part textABC05, and if they did, then they exist.
Thank you for all your assistance.

It might be worth checking out the FILE_SEARCH() function.
