FAQ - Frequently asked questions

Almost every common audio format - depending on additional decoder libraries. A 'pure' 1by1 plays only MP3 by using the system ACM decoder which is present in Windows and also in newer Wine versions on Linux. To play many more formats like AAC, MP4, WAV, FLAC, OGG, WMA, you should add the BASS library possibly with Add-ons to 1by1's program folder. The download can be found on the More page. Important: As 1by1 is a 32 bit application, also the 32 bit versions of the DLLs must be used.

For the current track artist and title info from ID3 tags as well as possible cover art are shown in the Big view area which can be placed above or below the track list. The content of the Big view can be adjusted individually in the settings. The ID3 title can also be shown in the window title. For cover art make sure that the option Show track/folder related pictures (Settings / Window style) is set. Tag titles and additional file informations can also be shown in the file and playlist view by choosing an Extra column (Settings / List and tree).

Shuffled play is only possible for the currently shown list. But you can fill the list with all tracks of a path by calling Show subfolder contents from the tree context menu. If this does not work in rare cases, use Find files with no search term. Alternatively you can fill the toggleable playlist view with tracks and then shuffle this list. The playlist view will be kept while a modified file list will be overwritten on directory change.

The installer is a selfextracting ZIP file. It simply copies the files to the selected folder and creates a desktop icon. To copy the files to the default 'Program files' folder, it is usually needed to run the Installer 'As administrator' (right button). No admin rights are needed if you install the program to a folder where you have write access. The files of the distribution can also be extracted with an archive utility (e.g. 7-Zip). Malware alarms? Please see the Contact page.

The program tries to behave portable: If it finds write access to its folder, 1by1 will store its configuration files there. If not, the Roaming folder of the user profile is used for the future. To safely prevent 1by1 from using the user profile, the local/portable storing of the settings files can be forced with the option Force portable settings unter Settings / System. The option works only with write access to the program folder.
