#Mhw recompress chunk file archive
Or, write a new archive to disk to a temp file, then delete/rename the files. A more robust way to add a file to an archive would be to read it into memory, perform the operation, then write a new archive out to a temp file and then delete/rename the files. Note this is an IN-PLACE operation, so if it fails your archive is probably hosed (its central directory may not be complete) but it should be recoverable using zip -F or -FF. Sprintf(archive_filename, fileNames.at(i) )
#Mhw recompress chunk file how to
zip as described above.ĭo I use the lib wrongly right now? I open the files myself and store the data in the vector because I could not figure out how to make function open the file itself. The problem in this version is that the library creates many files with the same name in the. In the final version, just a chunk shall be read and stored in the program at one time. Please note that the program store the whole file in the std::vector filesdata. The program crash with files larger then 0.9 GB. Or you can specify custom file read/write callbacks. It supports archives located in memory or the heap, on disk (using stdio.h), There are simple API's to retrieve file information, read files fromĮxisting archives, create new archives, append new files to existing archives, or clone archive data from The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to The following text is written in the libary file(the libary contains only one file) so I guess it is not possible but I ask anyway to see if anyone has a solution or another approach so the program does not eat all the memory. Obviously I want the chunks to be merged together instead of being splitted in the zip. Right know, this does not work as I want, for example: if a file named problem.txt is divided into 10 chunks, I get 10 files named problem.txt in my zip folder. The computer that will run this program will also run another (heavy) application and therefore I want this compressing program to load a chunk of each file to prevent it to use a lot of RAM (max size of chunk = 0.5 GB ), compressing that chunk and then proceed the next chunk until all files are compressed.
I'm building a program with help of the library for compressing files with sizes up to 3GB.
