There are similar questions like this question, example Rename-item: Cannot rename because item at ... does not exist which gives the same error as the one I have. Mine is specific as the script works for some files, example
NB. I am not advanced in powershell scripting
| Files | Renamed |
|---|---|
| DbBackUpV4.bak | true |
| LongNameUpTo50Chars.bak | true |
| Db[BackUp]V4.bak | false |
| AnyNameWithChars[].bak | false |
the database backup files are named differently, I just noticed that the ones with [] charaters generate the error Rename-Item : Cannot rename because item at '' does not exist.
out of curiosity I tried using just one of the characters [ and I got another type of error Message:"Cannot retrieve the dynamic parameters for the cmdlet. The specified wildcard character pattern is not valid: DbBackUp[be9e-Full.bak"
I also check for windows file naming rules the characters [] are used for file naming, which makes me conclude it has to be something with power shell scripting.
$Now = Get-Date -Format "ddMMyyyyhhmmss"
$NewFileName = $FileNameWithoutExtensionShort + "_DWArchive_" + $Now + $num + $BackupFileExtention;
$num = $num + 1;
if ($NewFileName.Contains("[") -or $NewFileName.Contains("]") -or $NewFileName.Contains("-")) {
#Remove special characters from name before renaming
Log -Message "Remove special characters from name ($NewFileName) before renaming"
$NewFileName = $NewFileName.replace("[", "_").replace("]", "_").replace("-", "_")
}
# if($_.Exists){
# Rename-Item -Path $_.FullName -NewName $NewFileName. #This also fails
# }
Rename-Item -Path $_.FullName -NewName $NewFileName
This is the part of the script, it is inside a loop, and $_.FullName gives me the name of the original file.
What exactly am I missing? Thanks for helping
