Script removing files smaller than 10kb - script development problem.

JohnnyJohansson

Hi.

I have some LAS files that contain nothing, but my sub program dosent like empty files, so I'm trying to write an script that removes all files smaller that ex. 10kb.

But I cant get it to work, and I'm not good at python or any type of programming...

This is the code I have been trying to get to work:

import os, os.path

for root, _, files in os.walk("C:/some/dir"):
for f in files:
fullpath = os.path.join(root, f)
try:
if os.path.getsize(fullpath) < 10 * 1024: #set file size in kb
print fullpath
os.remove(fullpath)
except WindowsError:
print "Error" + fullpath

Thanks!

 

This is the working code with inputes for script tool for Arcgis.

I havent tested the error code function sinse it just worked..

import arcpy, os, os.path

Path = arcpy.GetParameterAsText(0)
Size = arcpy.GetParameterAsText(1)
CalSeize = ( int(Size) * 1024)
arcpy.AddMessage ("Path to search for files: " +(Path))
arcpy.AddMessage ("Min file seize to keep: " + (Size)+"Kb")
arcpy.AddMessage ("Calculatde min size: " + str(CalSeize) + " bytes")
for root, _, files in os.walk((Path)):
    for f in files:
        fullpath = os.path.join(root, f)
        fileSize = os.path.getsize(fullpath)
        if fileSize < CalSeize: # Calculate min file value to keep
            try:
                os.remove(fullpath)
                arcpy.AddMessage ("Removed: " + f + " with the size: " +  str(fileSize) + " bytes" )
                print 'removed: ' + f + ' file size: ' + str(fileSize) + 'bytes'
            except WindowsError as ex:
                print "Error: " + fullpath
        else:
            print fullpath + f + ' is within min. File size: ' + str(fileSize) + 'bytes'
