I’m trying to convert a pdf file to text file using Ghostscript and while converting I was able to convert 11 pages pdf file successfully but when I tried the same for 110 pages file I couldn’t convert it.
I did the same on my Linux server and it is converting absolutely fine irrespective of number of pages I pass.
If someone has encountered this issue before on windows? Or am I missing something while doing the conversion on windows?
Is there a limit of maximum number of pages ghostscript can process on windows

According to Wikipedia:
Thumbnail caching was introduced in Windows 2000; wherein the thumbnails were stored in the image file's alternate data stream if the operating system was installed on a drive with the NTFS file system.
Here, it's clear that Windows used to associate thumbnail information directly with a file using its alternate data stream (on an NTFS file system). However, since Windows Vista:
...thumbnail previews are stored in a centralized location on the system... The cache is stored at %userprofile%\AppData\Local\Microsoft\Windows\Explorer as a number of files with the label thumbcache_xxx.db (numbered by size)
However, I have yet to find anywhere that explains how Windows associates individual thumbnails in the cache with specific files on the file system.
Does Windows associate the thumbnail image with the checksum of the file? It seems unlikely/nonoptimal because Windows would have to compute the checksum of every item in a folder (when accessed) if it wanted to properly display the correct thumbnails.
Does Windows use something lower level like the NTFS file ID of the file? But then how would it work on other file systems like FAT which don't assign fixed file IDs?
I have yet to find any good answers so I would really appreciate any help I could get!
I have two notepad files.
One created in Windows 7 and another in Windows 10.
But both have different size (even same content) and somehow different 'format' that make my other program read both differently.
How do I check the differences? How can I make notepad that same regardless the Windows version?
Both file just have the word DATA
It looks like Encoding.
Windows 7 is saving as ANSI, while 10 is saving as Unicode (UCS-2 LE BOM), probably.

I'm using PDFCreator Free, which uses Ghostscript (gswin32c.exe) behind the scenes to produce PDF files by printing to a virtual printer. I'm using it in batch mode, which generates the PDF, then launches a custom batch file.
Some large files take several minutes to complete, during which time there is no way to determine progress (my batch file doesn't launch until the process is done). I can see the gswin32c.exe file running in Task Manager, and in the %Temp%/PDFCreator directory, the Spool and Temp directories get some content.
Is there a way to determine Ghostscript's progress (or at least the number of pages already generated) so I can report this from somewhere? I can't see or change the command-line arguments sent to Ghostscript, since it's called from the proprietary PDFCreator software. Is there a file somewhere that contains some type of status or metrics on the running GS process?
Basically, no. It depends slightly on the exact command-line arguments (which you haven't given), but I imagine all the feedback is being suppressed.
Note that pdfwrite doesn't create any pages at all until its finished processing the input, and there's no easy way to determine how many pages are in the input PostScript program.
I'm able to use iMacros for Chrome and read from a .csv file perfectly fine on Windows 8.
But the exact same script/setup no longer works when using Windows 10.
Any ideas how I can make it work?
Ok so it turns out windows 10 was not the culprit at all. iMacros works exactly the same on both windows 8 and 10 as far as i can tell.
The issue is that the .CSV file i was reading from somehow had a huge ammount of empty cells (and hence loads of commas), which made the file too big to be read.
I deleted the rogue commas, and now all is well.
In our software we need to be able to convert SPL files which printer drivers write to the C:\Windows\System32\spool\PRINTERS folder to PDF files. For SPL files in PCL format we perform this conversion using pcltool.exe from VeryPDF, which mostly works fine. However we are having trouble with SPL files generated by the printer driver "Canon iR-ADV C5235/5240 PCL6". As an example, the following SPL file results from printing out a single page in notepad with the word "something" on it:
http://files.etvdzs.info/00025.spl
Converting 00025.spl using pcltool.exe results in a 70-page PDF with a row of garbage characters at the top of each page. Attempting to open 00025.spl using other PCL viewers gives similar results. We asked VeryPDF and they told us it is not a valid PCL file.
Can anybody tell me what exactly is invalid about this file? Is there any possibility of converting it to valid PCL or otherwise extracting usable data from it?
Incidentally, we had a similar problem with Postscript files generated by the "Canon iR-ADV C5235/5240 PS3" printer driver. There were binary sequences beginning with $CDCA10 and ending with $FFFF000000000000000001 at various positions in the files. After removing these sequences, we were then able to convert the files as normal. I tried a similar solution for the files generated by "Canon iR-ADV C5235/5240 PCL6", but unfortunately was not successful.
EDIT (13 Sep 2013): It seems that the binary sequences are CPCA codes. I was able to obtain documentation about CPCA by signing up for the Canon Developer Support Program at the following URL:
https://www.developersupport.canon.com/user/register
After reading this documentation, I wrote a program to remove CPCA codes from spool files. This is the result of running the program on the file 00025.spl from above:
http://files.etvdzs.info/00025.cleaned.spl
Unfortunately this still doesn't seem to be a valid PCL file :-( Can anybody tell me what exactly is wrong with this file? Is there any possibility of converting it to valid PCL or otherwise extracting usable data from it?
P.S. The program I wrote does successfully convert spool files generated by the printer drivers "Canon iR-ADV C5235/5240 PCL5c" and "Canon iR-ADV C5235/5240 PS3" to valid PCL and Postscript respectively, so I don't think it is a simple matter of the program not working.
Odds are you have something like an EMF or similar file here. Ensure that the server queue (if you are printing to a network printer) is set to 'Render on client computer'. I would also look to set the Print Processor to Winprint RAW. It could also be that the Canon PCL printer isn't as generic as you'd like. You can always try a different PCL driver and see if your converter and the Canon device support the format. To confirm that the issue isn't the Windows Spooler you can set the port to FILE and/or use a capture utility to write out what the printer would actually receive post all processing. If that works but the SPL doesn't then you have a Windows Spooler and/or processor issue.
