Hi Don,that code I used was used from another thread on here about comparing two text files. So I'm not sure what that bit is doing, what I thought that was doing was taking the differences in file 2 compared to file 1 and printing them to another file??

I dont have access to the machine at the moment but I should have privileges to read and write files as I do this all the time, after the first error I opened and saved LOGtoolnr.txt so the file actually exists now but it still can't be accessed.

How could i clean up my code to just print the differences to another file?

Thanks

tiffcmp

TIFFCMP(1)						      General Commands Manual							TIFFCMP(1)

NAME

       tiffcmp - compare two TIFF files

SYNOPSIS

       tiffcmp [ options ] file1.tif file2.tif

DESCRIPTION

       Tiffcmp compares the tags and data in two files created according to the Tagged Image File Format, Revision 6.0.  The schemes used for com-
       pressing data in each file are immaterial when data are compared-data are compared on a	scanline-by-scanline  basis  after  decompression.
       Most  directory	tags are checked; notable exceptions are: GrayResponseCurve, ColorResponseCurve, and ColorMap tags.  Data will not be com-
       pared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal.	By default, tiffcmp will terminate if  it  encoun-
       ters any difference.

OPTIONS

       -l     List each byte of image data that differs between the files.

       -z number
	      List specified number of image data bytes that differs between the files.

       -t     Ignore any differences in directory tags.

BUGS

       Tags that are not recognized by the library are not compared; they may also generate spurious diagnostics.

       The image data of tiled files is not compared, since the TIFFReadScanline() function is used.  An error will be reported for tiled files.

       The pixel and/or sample number reported in differences may be off in some exotic cases.
