On Windows Aseprite will not open .ase and .png files in the existing Aseprite instance. This is a workaround for that. Combined with VsCode and this extension you can open files from VsCode and straight into Aseprite.
In settings.json:
"openInExternalApp.openMapper": [
{
"extensionName": "png",
"apps": [
{
"title": "Open in Aseprite (.png)",
"shellCommand": "path to file/aseprite_opener.ahk ${file}"
}
]
},
{
"extensionName": "ase",
"apps": [
{
"title": "Open in Aseprite (.ase)",
"shellCommand": "path to file/aseprite_opener.ahk ${file}"
}
]
}
],
