How can I get a full name for a folder that starts with "data_" and ends with random numbers and characters?
I want to get a folders name inside Temp Directory.
Not sure how to even start. 🤭
Any suggestions? 🤔

A process of mine opens a HML file, modifies it and then saves, closes it.
I then need to run an.exe that opens this file right after this.. However, nothing that I find on this forum works that supposedly tests to see if the fie is still open, ready to be used by another process.
Right now, I just Sleep(2000) .
I would like something cleaner than this.
This function, for example, returns False when nothing has it opened or if I open the file with notepad or any other editor.
I am running on a win7 laptop, if that has any bearing.

$input = $CmdLine[1] $bytes = 1000000 ; 1000000 for 1 MB, 1000 for 1 KB $size = FileGetSize($input) $file = fileopen($input, 16) $max = ceiling($size / $bytes) for $i = 1 to $max $data = fileread($file, $bytes) $output = $input & '_' & $i & 'of' & $max filewrite($output, $data) next ^file split
file path for a 20MB "video.mp4" is input, it will be output as "video.mp4_1of20", "video.mp4_2of20", etc. change $bytes to affect the split files size, this example made them 1MB (10^6 bytes)
$input = $CmdLine[1] $name = stringtrimright($input, 1 + stringlen($input) - stringinstr($input, '_', 0, -1)) $split = stringsplit($input, 'of', 3) $max = $split[ubound($split) - 1] for $i = 1 to $max $in = $name & '_' & $i & 'of' & $max $file = fileopen($in, 16) $data = fileread($file) fileclose($file) filedelete($in) filewrite($name, $data) next ^ file join
file path for any of the "video.mp4_Xof20" segments is input. the "video.mp4_Xof20" segments are read and written to "video.mp4" and then deleted, leaving the newly joined "video.mp4" in the end
i made this today because i had a big file that i couldn't really open. i split it into 1000 chunks to make processing and stuff easier. i've also used it to split files to just under 25MB segments so i can attach and mail big files over gmail which is silly but it worked

Hi, here are few functions for the ListBox.
I have searched the forum, but most of the functions are for listview, so i took one example code from melba23 (clear selection) and
wrote few more functions. (Because my current project needs them).
These functions work only on a Multi-selection ListBox .
Edit: Only 1 function does not work with single selection box.
The functions do: Clear Selection, Delete Selected items, Invert Selection, Move selected items up and down.
The example code has 2 Listboxes. The selected items on the left ListBox can be moved up and down. The right Listbox has buttons for the other functions.
