try saving the file to a simpler folder ie c:\test

many times it is either the source and/or destination file name that isn't appreciated by the software.

i try to create attribute table for Fdr(flow direction) , but in the usage they said that :

It is not possible to build a raster attribute table for a raster dataset that is a pixel type of 32-bit floating point。

and i went to check it . my dataset seems to a pixel type of 32-bit floating boat , what should i do?

That is indeed the error, you have to convert it to integer format, it seems that you have obtained floating point values for whatever reason.  I would revisit your workflow to ensure that you are using the correct input file.

i download the input file from hec-geohms official website and it is a

example date . the format of DTM(DEM) is (w001001.adf) . i cant add this

data from GIS add data tool . i input the by pool file into GIS .

and how can i convert floating point to integral data?

thank you

if is was an esri grid (appears to be), it should have been contained in a folder, did you remove it?... you simply navigate to the folder, with tthe add data button and select it.  It you ever do get it loaded, use the spatial analyst's Int tool.  It will truncate any decimals, so if this is a problem, you can upscale by a factor of ten prior to taking the integer of it, but you will have to remember that you are working ith a scaled raster.
