I need to remove a small right arrow at the end of the data (an ASCII EOF marker) in a text file without removing any other data.

A script would need to look in a specific folder, ie c:\data\ and look at each .txt file and if it sees this end EOF marker then it needs to remove it and resave the file.

Test if this works for one file:
Get-Content "X:\path\file.txt" -Encoding Byte | ? {$_ -ne 0x1A} | Set-Content "X:\path\newfile.txt" -Encoding Byte

If it does, we can use this for the entire folder. It basically reads a file byte by byte and writes only those bytes not equal to 0x1A (or 26 decimal,  which is the code for ASCII EOF)

HTH,
Dan

Is this to be inserted in a batch file?
If yes, I tried and it just blinks fast and nothing happens.

Nope. It's a powershell script.

Ok, it works well!!
How can we modify it to look at all txt files in folders?

$origFolder = "X:\your\path"
$newFolder = "X:\your\new\path"

$files = gci $origFolder -Recurse -filter "*.txt"
foreach ($file in $files) {
    Get-Content $file.FullName -Encoding Byte | ? {$_ -ne 0x1A} | Set-Content "$newFolder\$file" -Encoding Byte
}

Thanks. Will this form new files on it's own and it's own naming convention?

This will create new files in the newFolder folder. Basically it will copy the original files, minus the offending character.

That folder must exist, or the script will throw an error.

If no files exist in the folder, will the script still run, but nothing will be created?
