clrmame Discussion / How to best deal with progetto-SNAPs?
« on: 28 July 2023, 16:57 »
Hello,
handling progetto-SNAPs DAT files has become increasingly painful over time. I have the zipped files, snap.zip and titles.zip stored in a SMB mount, each in its own rompath. Until now it was slow-ish but manageable, however attempting to scan 0.254 zip with 0.256 DAT file (pS_Snap_NS_20230728_(cm).zip) in preparation for a rebuild has not completed for over an hour. I already have missing check disabled, same for the deeper check. I have now moved the file to a local SSD just to see if the network is the culprit but the scan has been going on for several minutes now. The last sign of life is the query whether I want to delete the incorrectly sized files.
Should the files be stored unzipped or zipped? [1] says that speed is gained by not compressing but [2] says that unpacked sets are slow as the hashes need to be recalculated instead of being picked up from the zipfile itself. Thanks for the input.
