Что такое формат файла TLS?
A .tls file is a logon-screen theme package created by TuneUp Styler, a module bundled with TuneUp Utilities from TuneUp Software. The file packages everything needed to replace the standard Windows welcome screen - typically one or more background images alongside positioning metadata that instructs TuneUp Styler how to apply the theme.
The format targets Windows XP, Vista, and 7, operating systems where the logon-screen UI could be replaced through software hooks. The .tls container is a proprietary binary package with no published magic signature; it is recognised only by TuneUp Styler itself. Some files have an archive-like internal structure and can be partially inspected with 7-Zip, though the internal layout is not officially documented.
TuneUp Software was acquired by AVG in 2011, and the product line eventually became AVG PC TuneUp (now under Avast/Gen Digital). Classic TuneUp Styler logon-screen customisation is no longer possible on modern Windows because Windows 8 and later removed the replaceable logon-screen UI entirely, making .tls files effectively obsolete.
Other TuneUp Styler theme formats include .TVS (visual styles), .TDL (desktop-look packages), and .TSA (TuneUp Styler archives). Note that .tls is also used by Sony / MAGIX Sound Forge for an unrelated audio time-locator sidecar file - if your file originates from an audio project rather than a TuneUp Utilities installation, it belongs to that separate format. The Windows .THEME format handles broader desktop appearance settings by contrast.
Безопасность и защита
РИСК: MEDIUMA TuneUp .tls logon theme modifies Windows system UI, so historically applying one required system-level changes - only apply themes from sources you trust, and avoid them entirely on modern Windows where the mechanism is unsupported and could destabilise the logon screen. The classic TuneUp suite is discontinued, so don't download it from third-party 'free TuneUp' mirrors, which frequently bundle adware/PUPs. If your .tls is actually a harmless Sound Forge markers file, it carries no such risk. Scan any file from an untrusted source.

в двух словах- Sony / MAGIX Sound Forge time-locator (markers) file - Sound Forge audio editor saves a list of time markers/locators as .tls alongside an audio file.
- Generic tool/settings file - A few utilities use .tls for their own list/settings data; identify by the creating program.
