Why does this error happen?
If you have seen this message, the cause is usually one of these.
explorer.exe
File Explorer is holding it. Turn off the Preview pane (Alt+P) and move to another folder — that alone usually releases it. If you end it, the taskbar disappears for a moment and comes back.
SearchIndexer.exe
Windows Search is building its index. It releases the file by itself in a moment, so there is no need to end it.
Clears read-only, hidden and system attributes, then deletes (inside folders too)
A folder past 260 characters cannot be opened or deleted in Explorer. It cannot even be renamed.
How do you deal with it?
- Move to Recycle Bin
- Delete
- Close the program and delete
- Unlock and delete
- Delete after restart
Download LetGoFile, drop the file on it, and it tells you which one of these it is.
