Hello,
I have several folders containing ascii files in each. The filenames within those folders are a grouping of numbers and letters corresponding to year, day, and other instrument characteristics
(e.g 8358d47a.tps, 8358h41a.tps, 8358l35a.tps). Unfortunately there isn't a pattern or order to the filenames beyond the first couple digits which are connecting to the parent directory to easily open the files consecutively.
I want to open each file, read the data, then close and repeat on the next file. Is there a way to loop through the files in each directory without knowing specifically what the filenames are? I'm struggling with how to do this since.
Thank you. Sincerely,
Morgan

Should be something like this:
files = file_search('/path/to/your/files/','*.tps', COUNT=nfiles)
for i=0, nfiles-1 do begin
nlines = FILE_LINES(files[i])
data = STRARR(nlines)
OPENR, lunit, files[i], /get_lun
READF, lunit, data
CLOSE, lunit
FREE_LUN, lunit
; Do some stuff here
endfor
