See Age of Empires 3 HEX-code, Cheat-code here!

Note: This procedure involves editing a game file; create a backup copy of the
file before proceeding. Use a text editor to edit the "proto.xml" file in the
"data" directory in the game folder. Note: You may first need to uncheck the
"Read Only" attribute of that file's properties in Windows Explorer. Search for
the text "CrateOf". You will find CrateofFood, CrateofCoin, CrateofWood,
CrateofFoodLarge, CrafteofCoinLarge, and CrateofWoodLarge. For all these
entries, find the tag "InitialResourceCount" and change the count to whatever
desired. For example, the normal crates each have "100.000" of the resources.
You can change the "100" to "99999.000", etc. Make sure you do this for all the
crates; sometimes a map will give you a large crate of something, and smaller
ones of something else, etc. This works best because every map you play in
campaign or skirmish starts you with some "crates" of resources, which your
settlers will gather out. This will edit the crates to have huge amounts of
resources in them. However, it still takes a long time to get the resources out
of the crate for the settlers, because there are so many. If you are impatient,
search for "Settler" in the "proto.xml" file and find the tag for GatherCrate.
Change the value to whatever desired, preferably something very high (for
example, "99999"). They will pull the resources out of the crate instantly.
