This argumentMUST BE first argument if you plan to use it.

When start, type setting file name afterprefetch.exe to load different settings.
If no ini provided, default isprefetch.ini.
All ini should place at same folder withprefetch.exe see details below:

>prefetch.exe iexplore.ininew QSettings(QCoreApplication::applicationDirPath() + "/" + <your value goes here>, QSettings::IniFormat);

Good example:

// Skip statup but do not change ini>prefetch.exe -skipStartup

// Skip statup and change ini>prefetch.exe iexplore.ini -skipStartup

Bad example:

// *.ini is not the first argument>prefetch.exe -skipStartup iexplore.ini

// *.ini is not place at same folder with prefetch.exe// Or called try to use path instead of file name>prefetch.exe C:\OtherFolder\iexplore.ini>prefetch.exe ..\OtherFolder\iexplore.ini

Start prefetch, run startup item, exit.

According tothis research, some use case won't require to keep a background service.

Do not run startup item.

While debug and optimize scan results, it's not necessary to actually read files.When-scanOnly, skip read but run regex only.

Notice that-scanOnly still try to open the file,
so you can know if a file is not accessible.
A simple test showfile.open() without read indeed read less MB from disk than scan and read.
