Lee Lee This is exactly what I was looking for, and thanks for confirming my hunch that get-content is not great with large files. Helpful tip: You can express numbers like this I'd suggest using a stringbuilder to concatenate individual lines before calling add-content to write content otherwise this approach is very slow.

CVertex you do realize that your script reads the entire file into memory first? So that will never work for a truly huge file multiple GBs. Show 4 more comments.

Using Measure-Object is probably better than stopwatch, but this is good. It took me 37 minutes to split a 10gb file. The solution this was derived from ran for 30 minutes before I cancelled it and hadn't yet succeeded in getting the file into memory, perhaps because I didn't have 10gb of memory available. Split-File supports this functionality with the -rc RepeatCount parameter.

Wildcards are permitted. Unlike Path, the value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences. Typically this is 0 or 1 but it can be any number of lines.

Josh Josh Might want to turn count into a long when you want to have more lines per file. Also, this script runs out of memory if you write huge files.

I waited 10 minutes for the "answer" solution to ultimately accomplish nothing while I implemented this solution and it was finished in a little over 5 seconds.

It is quite fast indeed, I had to split a Mb file, it took 19s to run. The accepted solution ran for 73! This is definitely my choice. This is basically an exact copy of an answer above — reggaeguitar.

Shantanu Gupta I've made a little modification to split files based on size of each part. Size must be expressed in MB. If you need bigger chunks you can increase it by modifying the script.

The delimiter character is by default omitted in all the substrings, to include them it must be enclosed within parenthesis. By default, all the possible substrings are generated. If the substrings are more than the specified number, then the leftover substrings are appended to the final substring.

Non-negative values are allowed, zero returns all the substrings. It is enclosed within the braces and must evaluate either to true or false. The syntax for options is below and it can only be used when the Max-SubStrings parameter is used. Split "-". Split ",". Split ". This example will show how to split and generate substring based on regex and to split MAC addresses. The split path is used to return the mentioned part in a path.

It can be a parent folder, a file name or a sub folder. Thus, the article is covered in detail about the split string method in PowerShell.
