arcpy.da.Walk()-- read KMLs, Personal GDBs, etc.

Question

I'm giving arcpy's Walk a shot, and I've run into a disappointing setback: It doesn't notice several file types I'd like to see.

For example, I'd like to see KMLs (supported by Pro???), Personal GDBs, PDFs, Word Documents, and zip files.

I don't even need to read the contents of things like Personal GDBs right now; I just want to know they're there. (Sidenote: It will read coverages but not recognize if a Personal GDB or KML is there???)

I'm disappointed because arcpy.da.Walk takes about 15 seconds to evaluate on test data, and the functions I'd built with os.path.walk (including filtering out shapefile component files, etc), takes about 70 seconds on the same data, but return things like PDFs.

Does anyone know of a way to get arcpy's Walk to see other files?

Could you possibly multithread the Listing and filtering?  Run the ListFiles, ListTables, ListRasters, ListFeatureClasses in parallel and then combine the results to maybe speed it up until another solution is found?

I'd add for @GhislainPrince  that Walk is returning Rasterbands as Featureclasses. There is another post on here I helped with and when I tested the Walk for Featureclasses, it returned a Rasterband file. This was within the last couple weeks in 3.1.

Hi Alfred,

community ideas are good way to go for that catalog pane "add file type" feature, also getting attached to ENH requests with tech support.

We have arcpy.da.Walk to get data we know about, for the data formats Pro doesn't know about the approach of os.walk seems right to me.   Your approach of a white and/or black list for your org's other data seems right.

Finally we've worked on arcpy.da.Walk in recent releases, there's improvements to the online doc, as well as improved results for KML, .geodatabase, .atbx, parcel fabrics in the Pro 3.x releases.

Cheers
