What is the best way to keep track that a certain file is the same one that has been previously looked/opened at.
I thought MD5 sums would be a good way but it seems that with the files I am working with (excel spreadsheets) this isn't a viable solution. Since once you open an excel spreadsheet (and not making any changes) somehow modifies the MD5 sum. One way to fix this (fix it so I don't change the MD5 when using my parser) is to copy the file then open the copy and delete the copy afterwords. But I am not sure this is the best solution, since I can't stop others from opening the file in turn changing the MD5. My current solution is to use file path, filename, file size/modified/changed to determine if this is the same file I have parsed previously which is saved in a text file (filename.info). This file is then later parsed if the same filename.info exist when running my parser.
