[FEATURE] Invalid Mod File Detection

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe.

There are many times when zip files land in the directory that aren't actually mods when downloading from 3rd party sites.

Examples are:

• Zip files that contain the mod zips
• RAR files (these usually contain the mod zips also, and are done as RAR so game doesn't pick them up and error)
• Zip files that are just invalid, ie. no modDesc.xml file in them

Describe the solution you'd like

Check for valid mods, and suggest remedies for invalid ones.

Such as:
For RAR and ZIp that contain actual mod Zip files, report them and suggest unzipping then deleting them.
For Zip files that don't contain other Zip files, and aren't valid mods, suggest removing them completely.

Anything else?

Das Issue nennt keine Dateien, Tests oder Einstiegspunkte. Beginne damit, den bestehenden Ablauf für den Mod-Import oder -Scan zu lokalisieren, und ermittle dann, wie Archive und modDesc.xml derzeit behandelt werden; abgeschlossen ist die Aufgabe, wenn ungültige Archive identifiziert und die angeforderten Abhilfemaßnahmen vorgestellt werden, ohne gültige Mods zu beeinträchtigen.
