Opening SLM files
Did your computer fail to open a SLM file? We explain what SLM files are and recommend software that we know can open or convert your SLM files.
What is a SLM file?
The .slm file extension can be linked to files being generated when the user utilizes the Gallery Lock. Gallery Lock manages and stores pictures and videos by hiding them to other users. Developed by Morrison Software, Gallery Lockis an app for Android that allows users to hide photos and other pictures on their smartphones.
The .slm file is an encrypted/ encoded file type that represents sthe altered version of the original "hidden" picture which is located in a hidden folder on the SD card in the following location: /mnt/sdcard/.gallery_lock/. Basically, 1024 bytes of data is added to the image to put it into hiding and the extension is renamed from .jpeg (for example) to .slm. It, of course, uses password protection to be able to unhide and open the file.
Software that will open, convert or fix SLM files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
