Got it — thanks for the clarification. Below is a single-line PowerShell command you can paste into the folder. It will:
* Look for files with Snapchat- in the name.
* Try several shell/EXIF properties in this order: System.Photo.DateTaken, Date, Content created, System.DateCreated, System.FileSystem.DateCreated, System.ItemDate, System.DateModified.
* If none of those are present, it falls back to the file system CreationTime.
* Renames Snapchat- → IMG_<YYYYMMDD>_ and keeps the rest of the name.

One-liner (paste as-is):

<syntaxhighlight lang="powershell">Get-ChildItem -File | Where-Object { $_.Name -like '''Snapchat-''' } | ForEach-Object { $dt=$null; try { $sh=New-Object -ComObject Shell.Application; $f=$sh.Namespace($_.DirectoryName); $i=$f.ParseName($_.Name); $props=@("System.Photo.DateTaken","Date","Content created","System.DateCreated","System.FileSystem.DateCreated","System.ItemDate","System.DateModified"); foreach($p in $props){ if(-not $dt){ $v=$null; try{ $v=$i.ExtendedProperty($p) } catch{}; if($v -and $v -ne ''){ if($v -is [datetime]){ $dt=$v } else { try{ $dt=[datetime]::Parse($v) } catch{} } } } } } catch{}; if(-not $dt){ $dt=$_.CreationTime }; $datestr=$dt.ToString('yyyyMMdd'); $newName = $_.Name -replace 'Snapchat-', "IMG_${datestr}_"; Rename-Item -LiteralPath $_.FullName -NewName $newName }

</syntaxhighlight>

Notes
* If you want to process subfolders, add -Recurse to Get-ChildItem.
* CreationTime is used as the final fallback (this is the typical "Content created" filesystem value). If you prefer LastWriteTime instead, I can switch the fallback.
* If any file still doesn't pick up the expected date, paste one example filename (and show dir /T:C "filename.jpg" output if possible) and I’ll diagnose why that file lacked the metadata property.

Want me to return a version that runs recursively and logs original → new names to a CSV?
