Extract text from Thumbnail cache files (SLM)
To convert SLM Cache files to another format, you need Samsung SLM Service or other System software.
To convert other file formats to the "Android Thumbnail Cache" file type, you need software like Samsung SLM Service or a similar tool.
The .SLM file extension most commonly functions as an Android media thumbnail cache, specifically managed by the Samsung SLM Service. These files store pre-rendered, low-resolution versions of images and videos to help the native Android gallery application load faster. The primary disadvantage of this format is severe storage bloat; .SLM files frequently grow to multiple gigabytes as they cache thousands of images, refusing to delete old thumbnails even after the original photos are removed. They are proprietary database files, meaning they cannot be opened by standard image viewers, web browsers, or basic photo editors without an active Android environment.
Beyond Android devices, the .SLM extension is also used for POS (Point of Sale) system menu files managed by the SpeedLine Menu Creator, and as Selective Laser Melting layer files produced by the SLM Build Processor for industrial 3D metal printers from Nikon SLM Solutions. These machine-code files represent sliced 2D layers for 3D printers, locking your geometry into hardware-specific build instructions. Reversing this back into a workable STL or OBJ model is highly challenging.
Because .SLM files encompass proprietary cache databases, closed POS menus, and compiled 3D printer machine code, standard online converters fail to process them. They lack standard headers and structural documentation. If our analysis detects supported underlying image data (like embedded JPG or PNG thumbnails) or valid text strings, viewing or conversion may still be possible.
Convert.Guru analyzes your SLM file, detects the exact format, and lets you read the text inside.
Users also converted SLT, SLV, SLDASM, JPG, SLN, 002, STL, SKM, ZIP, PMD, PDF, PNG and EXE files.
If you want to convert SLM file to CFM, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL or PLY, you can use Samsung SLM Service or similar software from the "Android Media Thumbnail Cache" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to SLM, try Samsung SLM Service or another comparable tool in the "Android Media Thumbnail Cache" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SLM converter.
