Windows copy dialog stalls on one bad file or keeps asking what to do with duplicates? Ultracopier, a free open-source replacement (formerly Supercopier), takes over copy and move jobs with a queue, pause and resume, and smarter handling of conflicts and errors.
How does Ultracopier manage copy jobs?
Ultracopier places transfers in a copy list, where jobs can be monitored and controlled. It can merge multiple copy windows into a single view, which keeps several active transfers together. The progress display includes speed information and remaining-time estimates; different estimate algorithms are available.
Pause and resume controls let users suspend a job and continue it later. Performance options switch between Ultracopier's own buffered, multi-threaded copying and the native Windows method. The paid Ultimate edition adds a speed limit and checksum verification.
What happens when a file already exists?
When a destination contains a file with the same name, Ultracopier's collision manager presents actions for resolving the conflict. Options include overwriting the existing file, overwriting only when the incoming file is newer, or retrying the operation later. Advanced renaming rules provide another way to deal with name conflicts.
How does it handle copy errors?
An error during a transfer can be managed from the copy workflow instead of forcing the entire job to end immediately. Ultracopier supports resuming after an error and provides error-management controls for deciding how to proceed. This gives users a way to continue with remaining files when an individual item cannot be copied.
Can the interface be customized?
Plugin support extends the program's available features, and multiple skins change its appearance. Ultracopier also supports multiple interface languages.
