No reliable information identifies a vendor, application, platform, or published specification for the .foldershareoverlaydeleted file extension.
The extension may be used for software-specific data, but its purpose cannot be confirmed from the extension alone.
There is no known application that opens a .foldershareoverlaydeleted file as a normal document. Opening it in a text or binary editor may show its contents, but may not produce useful or meaningful information.
Do not rename or delete the file if it is located inside an application's data or synchronization folder, because the owning software may require it for its internal state.
The .foldershareoverlaydeleted file cannot be meaningfully converted without identifying the software that created it and documenting its format.
If the file is software-specific data, the relevant application's own recovery or export features would be required to retrieve any associated data.
