Frequently asked questions
The field “limit to” is set to 1000 duplicates. What is the maximum number?
There is no maximum number. If you delete the number, there will be no limitation. Limiting the number of duplicates is useful if you want
to decide for each duplicate individually whether or not to delete it – in this case, a limitation means you do not have to rifle through an endless list of results.
Why can’t I delete anything from the Windows directory?
For safety reasons. I rather reluctantly remember the e-mail of a mother whose son deleted the entire hard disk including the Windows directory with Anti-Twin 1.0.
Quite a suboptimal result.
Why can’t I delete anything from the program directory?
For the same reasons that apply to the Windows directory.
Anti-Twin has found some duplicate MP3 files, but not all of them. Why not?
This is because the software ignores file names and only compares file contents. This is done by comparing the bytes of the entire file, i.e. Anti-Twin would not be able
to identify two MP3 files with the same song in different data rates (e.g. 128 and 192 kbps) as identical.
Although the human ear can hardly distinguish between the two MP3 files, their technical content varies considerably.
This also applies to images, e.g. JPG files showing the same picture, but with different compression rates (image quality).
The option “also find similar files” only helps finding more MP3 files if the songs are absolutely identical and e.g. only the MP3-headers are different, e.g. with another ID3 tag (internal song title).
Is it possible to run the program more than once simultaneously?
Yes, but running Anti-Twins simultaneously is only useful if each Anti-Twin searches a different hard disk drive. If two Anti-Twins search the same drive simultaneously, they block each other while accessing files.
Will the “low-priority process execution” slow Anti-Twin down?
Anti-Twin will in fact become slightly slower, particularly if other running programs also need much processor time. However, since Anti-Twin will not slow the PC down excessively during low-priority process execution, you can continue to work while Anti-Twin searches the drive. Using this option, you make the most of your time.
How does the pre-selection automatism work? (only V1.7)
The pre-selection considers several criteria as e.g. directory depth, length of the file names and write protection. It is not possible to configure the pre-selection.
I know the pre-selection is not useful for all users, but you cannot find one perfect solution for every individual user.
