An .icmt is an InfoWorks ICM transportable database — a portable snapshot of a model tree (networks, runs, simulations, events) exported from ICM via File → Export → Transportable. It is a ZIP container, and this app opens it locally: nothing is uploaded anywhere.

FULLObject tree (*.DAT)Model groups, networks, runs, sims — names, users, dates, relationships. Text format, fully decoded.

FULLSWMM networks (IWSWNET*.zip)Version-controlled NDJSON commit logs. Replayed into tables, drawn on a map, exported to CSV or a runnable SWMM5 .inp — verified by an in-browser EPA SWMM 5.2 engine.

FULLResults text (.rpt .prn .log)SWMM reports and InfoWorks logs — searchable text with section navigation.

FULLEvent blobs (RAIN/LEV)zlib-wrapped native event text (RED format) — decompressed and shown.

FULLNetwork previewsEmbedded BMP thumbnails of each network's GeoPlan, rendered inline.

PARTIALWallaby databases (.wdb)ICM's proprietary paged binary store ("numbatdata"). Header, page stats, and readable strings only.

LISTEDBinary results (.iwr .sps .2dr)Simulation result binaries — inventoried with sizes and hex preview, not parsed.
