$input = $CmdLine $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 $name = stringtrimright($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
I like and have been using TeraCopy, a third party program, for many years. Mostly it is a great program, but it does have some issues. On Windows XP for instance, Thumbs.db files could often hold up a copy or move process until the user manually responded to the error prompt. Some other issues I discuss below.
PLEASE NOTE - I am not related to or affiliated in any way with the 3rd party TeraCopy program developers.
ALSO NOTE - I myself have only tested TeraCopy Cure at this point, on Windows 7 (32 bit), and only with the free version of TeraCopy 2.27.
This program, TeraCopy Cure, is related to another one of my TeraCopy assistant programs, TeraCopy Timer, but aims at being simpler and quicker to use ... if lacking its more advanced features.
TeraCopy Cure is a frontend for TeraCopy and sets out to make up for its flaws and limitations.
One of those flaws is queuing order, and the limitation relates to a same destination issue.
You would think that queue order would be the same as add order, but that is not the case, and if you are doing a mix of COPY and MOVE then the COPY process could easily fail. It could fail with some source items, even if the COPY process has already started before the same source MOVE process begins ... especially if the destination folder is on the source drive ... only the currently copying file is locked to that process.
If you drag and drop another source for a same destination as an existing or impending COPY or MOVE process, then usually TeraCopy nicely adds it for you to that existing job. However, you might wish to avoid that, or it might occur during the testing phase of that active process, and then not be properly processed etc. But you are not given a choice and it just gets added.
HOW TO USE
See the right-click menu of the 'Batch List' (lowest field) and the right-click menu of the Tree field, for some useful options.
(1) If desired, enable 'Auto Start'. NOTE - Even if enabled, this can be bypassed.
(2) Set the destination folder, either by browsing on the tree or by dragging a folder to the Destination input field or label. Right-clicking on a folder in Explorer will also work, if enabled. The destination folder path will also show in the Tree if that right-click option is enabled.
(3) Then drag & drop source file or folder onto one of three five areas - Folder (Drive) Tree field, or COPY or MOVE buttons ... this now also includes the source input and label.
NOTE - If the Folder (Drive) Tree field is used, then you will additionally need to click either the COPY or MOVE button, to have that job added to the Batch List ... but this avoids 'Auto Start' if it is enabled. Drag & dropping to the buttons instead, saves on clicking, but starts the first job etc immediately if 'Auto Start' is enabled.
(4) If needed and ready, click the START button to run the first job and those that follow.
More information is included in program and in the NOTES etc sections below.
WARNING - Depending on the amount of content on your destination drive, and folder level depth, and the speed of your PC, display of the full path in the Folder (Drive) Tree can take a while to show ... if you have that (right-click) option enabled ... it isn't by default. I found this feature quite tricky to get right, and I'm still not 100% sure it is now full-proof.

Is there anything that does the same thing as this?
Namely I'm talking about detecting when something has changed on screen.
The FastFind library is crashing without any errors after running:
FFSnapShot($left, $top, $right, $bottom, 0) FFSnapShot($left, $top, $right, $bottom, 1) $diff = FFLocalizeChanges(0, 1) And then trying to overwritite the old snapshot (0 or 1).
If I use always different snapshot numbers its using too much memory and will eventually crash my pc.
I tried downloading older versions but they're not working and the author is inactive.
It takes 2 snapshots and compares them returning the area that has changed very quickly (left, top, right ,bottom).
Can anyone help me do this?
Looping PixelGetColor would require a bunch of extra code to my purpose and its not as efficient...
