I download a file.
Then I want to change the filename to filename without dots
ingewll,
Welcome to the forum. 
Without actually getting what the filename really looks like and what it should be in the end I’d say - Yes, it is possible.
But why would you like to do it for one file with PowerShell? And if you really want to do it in PowerShell - what have you tried so far? Are you aware that there are tools available for file rename jobs like PowerToys PowerRename?
Please keep in mind this forum is for scripting questions rather than script requests. We do not write customized and ready to use scripts or solutions on request.
We expect you to make an own attempt to get your task done or to solve your problem. If you have done so already please document here what exactly you have done and show your code. Then we probably might be able to help you step further.
Yes I have tried PowerRename and like it!
This is how far I have gone
$files = Get-ChildItem -Path /Users/curt-ingehenning/Downloads/_KLARA
foreach ($file in $files)
{
$newFileName=$file.Name.Replace(“.”," ")
Rename-Item $file $newFileName
}
OK, I assume it is about more than one file, isn’t it? 
Before we proceed: When you post code, sample data, console output or error messages please format it as code using the preformatted text button ( </> ). Simply place your cursor on an empty line, click the button and paste your code.
Thanks in advance

Regardless of that could you please post a few filenames as they are before and how they should look in the end?
Thank you.
Yes it is a few.
Examples:
Americas.Funniest.Home Videos S32E09 720p HEVC x265-MeGusta.avi = Americas Funniest Home Videos.S32E09.avi
Superman.and.Lois.S02E13.HDTV.x264-TORRENTGALAXY[TGx].mkv = Superman and Lois.S02E13.mkv
Star.Trek.Strange.New.Worlds S01E06 1080p WEB H264-CAKES.mp4 = Star Trek Strange New Worlds.S01E06.mp4
Alone.S09E02 720p WEB-DL AAC2 0 h264-LBR.mkv = Alone.S09E02.mkv
Again … please … when you post code, sample data, console output or error messages please format it as code using the preformatted text button ( </> ). Simply place your cursor on an empty line, click the button and paste your code.
Thanks in advance

And … I assume that are the filenames before, right? How should they look like after the renaming?
Americas.Funniest.Home Videos S32E09 720p HEVC x265-MeGusta.avi = Americas Funniest Home Videos.S32E09.avi
Superman.and.Lois.S02E13.HDTV.x264-TORRENTGALAXY[TGx].mkv = Superman and Lois.S02E13.mkv
Star.Trek.Strange.New.Worlds S01E06 1080p WEB H264-CAKES.mp4 = Star Trek Strange New Worlds.S01E06.mp4
Alone.S09E02 720p WEB-DL AAC2 0 h264-LBR.mkv = Alone.S09E02.mkv
First original and after = how I want it.
For the samples you shared this should work:
$fileList = Get-ChildItem -Path /Users/curt-ingehenning/Downloads/_KLARA
foreach ($file in $fileList) {
$newFileName = ($file.BaseName -replace '\.', ' ' -replace '\s*(S\d{1,2}E\d{1,2}).*', '$1') + $file.Extension
Rename-Item -Path $file.FullName -NewName $newFileName
}
Maybe something like this ?
$files = get-childitem 'b:\PS_test\*'
Foreach ($filename in $files){
$SE = (($filename.name | select-string -pattern 'S(\d{1,2})E(\d{1,2})').Matches[0].Groups[0].value).ToString()
$SeriesName = (($filename.name -split("$SE"))[0]).replace('.',' ').trim()
$NewFileName = $SeriesName +'.' + $SE + $filename.Extension
$SeriesDir = $($filename.Directory.fullName + "\$SeriesName\" + "$($SE.split('E')[0])\")
If(!(Test-Path $SeriesDir)){
New-item -Path $SeriesDir -ItemType Directory
}
Move-Item -Path $filename -Destination "$SeriesDir$NewFileName" -force
}
GOOD!
It didn’t handle the last file right
Superman.and.Lois.S02E13.HDTV.x264-TORRENTGALAXY[TGx].mkv
A new directory and subdirectory was created but the file was untouched original! Maybe the brackets in the filename caused it. Can be strange letters in original filename like ( ) , .
Can I change the destination to an external HD like G:/_TEST ?
So you used DejvDzi’s solution. 
Great … so I can go back to sleep. 
Yes I did. Thanks for your effort
You can change destination to G:/_TEST, if you need support-- write, I’ll be available tonight.
I tried this but no
Move-Item -Path $filename -Destination 'G:\_TEST\*' "$SeriesDir$NewFileName" -force
I tried this but no
$SeriesName = (($filename.name -split("$SE"))[0]).replace('.',' ').replace('[',' ').replace(']',' ').trim()
Hi, try this:
$files = get-childitem 'G:\_test\*'
Foreach ($filename in $files){
$SE = (($filename.name | select-string -pattern 'S(\d{1,2})E(\d{1,2})').Matches[0].Groups[0].value).ToString()
$SeriesName = (($filename.name -split("$SE"))[0]).replace('.',' ').trim()
$NewFileName = $SeriesName +'.' + $SE + $filename.Extension
$SeriesDir = $('G:\_test\' + "$SeriesName\" + "$($SE.split('E')[0])\")
If(!(Test-Path $SeriesDir)){
New-item -Path $SeriesDir -ItemType Directory
}
Move-Item -Path $([WildcardPattern]::Escape($filename.fullname)) -Destination "$SeriesDir$NewFileName" -force
}
Easy fix. Change parameter ‘-Path’ to ‘-LiteralPath’ in:
$files = get-childitem ‘b:\PS_test*’
PERFECT!! 100%
Thank you very much !!

Continues trying to compile this ps1 file to an exe.file and get this error message.
Spelling is correct.
