md5sum hashes of files in ppt/media
Attached is a file containing the md5sum hashes of the files in the /ppt/media sub-directory. It clearly shows that same file is saved many times with different names.
Bug is also present in 4.2.1 (rc1). Those test files seem to have no suffix? Could you please attach the pptx file in question so this can be confirmed. Those text files contain file listings with md5 hashes to show that many of the files are exact duplicates of the same file. I'll try and sanitise the presentation and upload it.

OK let's start again. Please ignore everything before Comment 8. I've uploaded three files: 1.) PowerPoint format file saved in MS Office PowerPoint 2010 which is 1.6MB big: 1.6M Sep 11 15:26 Staff_Update_September_2014_mso.pptx 2.) Open the file from 1.) in LibreOffice Impress 4.2.6 and save it as a pptx results in it more than tripling in size to 5.8MB: 5.8M Sep 11 15:31 Staff_Update_September_2014_lo.pptx 3.) Open the file from 1.) in LibreOffice Impress 4.2.6 and save it as a .odp results in it halving in size to 0.8MB: 883K Sep 11 15:50 Staff_Update_September_2014_lo.odp From what I can determine, when Impress writes out a .pptx file (i.e. file 2 above) then many of the images that are used in the presentation (logos, backgrounds, etc) get saved multiple times as separate copies of the same image. Possibly a problem in the export filter to .pptx? Confirmed under Ubuntu 12.04 x86 with: - LO 4.0.6.2 : size become 3.1 MB - LO 4.1.6.2 : size become 5.9 MB - LO 4.2.6.3 : size become 6.0 MB - LO 4.3.1.2 : can't be saved again as pptx, strange.. After unzipping the pptx, under 'media' folder we can see many duplicate images. In original pptx, 'media' folder only contains 21 image files. But after saving in 4.2.6.3 or 4.1.6.2, it grows to 269 files. In 4.0.6.2: 110 files. Not all image has duplicates, most duplicates is logo in footer (possibly because of master slides). (In reply to comment #12) Sorry..I forgot to tell, only tried with saving as pptx. ** Please read this message in its entirety before responding ** To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

Created attachment 93600 [details] Internal file listing of MSO.pptx, LO.pptx and LO.odp I received a presentation save in .pptx format by MS Office 2010: 1,4M Feb 7 11:28 mo_save_as_pptx.pptx I opened it in Impress and then saved it as a .pptx file without making any changes. The resulting file is more than four times as large: 6,5M Feb 7 12:11 lo_save_as_pptx.pptx Saving the same file as a .odp file without making any changes results in a file that is four times smaller than the original. 368K Feb 7 14:15 lo_save_as_odp.odp So it seems that Libre Office can import the .pptx file correctly but can not write it out correctly as a .pptx i.e. writing to .odp seems fine. Examining the resulting files reveals that when Impress writes out a .pptx file many of the images are copies of the images used in the presentation (logos, backgrounds, etc). Please see the attached archive for the file-listing of each of the three files i.e. MS Office .pptx, LibreOffice .pptx and LibreOffice .odp.
